Save water and make the green leaves evergreen.
The sages said, the use of courtesy, harmony is precious. China people are still harmonious, with peace in their hearts, harmony in their families, harmony in society and peace in the world. Man and nature should also establish the concept of harmonious coexistence. We humans are a part of nature, and we are the most advanced members of spirituality, energy and evolution. People obtain material resources from nature, occupy environmental space, pursue enjoyment, feel happiness and build an ideal kingdom. Facts tell us that resources are limited and the carrying capacity of the environment is limited. It should be clear that the only way to ensure human development is to increase revenue and reduce expenditure, and it should be made clear that the view of saving is the first one. Because only by practicing economy can we not exhaust resources and live in harmony with nature for a long time. Therefore, emphasizing water conservation is also the only way and effective measure to maintain harmony with nature. Saving water should be the basic obligation of citizens, social norms and national laws and regulations. The misconception that water is inexhaustible is harmful. This concept and behavior directly damage the water resources and environment on which human beings depend-the closest material basis in the relationship between man and nature. This positive and negative lesson is gradually realized by people in their own development process. For more than half a century, the experience of groundwater development in North China Plain has made us soberly realize that only by saving water can this green leaf in North China Plain be evergreen.
Water resources are the basic resources for social and economic development. Groundwater and surface water are water resources in different states and can be transformed into each other. Groundwater is an important part of water resources. In North China Plain, groundwater has become an important water supply resource. According to scientific statistics, the utilization of groundwater accounts for more than half of the total water consumption, close to 60% to 70%, and some cities rely entirely on groundwater for maintenance and operation. The life and production in rural areas are almost completely guaranteed by exploiting groundwater resources, and in some places, there have been years of water shortage and food shortage. At present, the groundwater exploitation in North China Plain is increasing year by year. Groundwater is over-exploited in a large area, and the groundwater level continues to decline. The combined descending funnel area of shallow groundwater and deep groundwater has exceeded 70,000 square kilometers. With the rapid development of industrial and agricultural economy, the momentum of industrial and agricultural water use, domestic water use and ecological water use in North China will increase greatly in the future, and the contradiction between supply and demand of water resources will become more prominent and more difficult to solve. There is no panacea for immortals, and the fundamental measure can only be to save water. Even if water is diverted from other river basins to quench thirst with distant water, the water-saving policy should be implemented.
Residents should save domestic water. Everyone should establish the concept of saving water and form the habit of saving water. The habit of saving water is a person's civilized quality. Of course, it can't be simply summed up as "not using water" or "using less water". To put it bluntly, washing hands before meals is hygiene. Can you say there is no water? Drinking enough water every day is a guarantee of good health. Can you say drink less water? In social development, per capita water consumption is one of the standards to measure the quality of life. There is little difference in the amount of drinking water between people, but there is a big difference in the water used for sanitation and bathing. Per capita water consumption reflects the way and quality of healthy living. The family life style of urban water heating and electricity supply is obviously the happiness goal that people pursue. Ensuring people's domestic water use is a major social responsibility. In this way, the improvement of people's quality of life will inevitably increase the per capita water consumption. Saving water in residents' life should be to cherish water, not to waste water, not to care about abusing water because of low water price, not to leak water, not to consume water unnecessarily and not to pollute water. We should choose water-saving appliances as far as possible, reduce water consumption and improve water utilization. In people's daily life, water is widely used and has great potential to save water, which is something that everyone should pay attention to in real life. It is a person's virtue to form a good habit of saving water in life.
Water for agricultural production should be saved. Planting, breeding and processing in rural areas are inseparable from water. Agriculture is a big water user in North China Plain, and it contributes the most to increasing water resources. In North China, the main agricultural water is groundwater, and the increase of grain, vegetables and fruits such as wheat and corn is ensured by pumping groundwater. In rural areas, the way of taking water by artificial earth wells has long been exhausted, and the phenomenon of pumping shallow groundwater and deep groundwater by mechanical wells is common, and the phenomenon of forced over-exploitation of groundwater is also common. Increasing grain production, water resources security and ecological balance have become a pair of contradictions in social sustainable development, and emphasizing agricultural water saving has become the fundamental way out for agricultural development. Agricultural water saving includes: adjusting agricultural planting structure; Select water-saving crop varieties; Adopt water-saving irrigation methods, methods and instruments; Supporting water-saving engineering facilities; Adjust the utilization of fresh water and brackish water resources and actively promote advanced and effective agricultural water-saving technologies. At the same time, we should attach great importance to agricultural pollution, especially water, soil and biological pollution. Special attention should be paid to preventing groundwater pollution, and problems should not be taken lightly when found. This kind of pollution will cause fatal damage to ecology, especially to life and health. Once the groundwater is polluted, it is difficult to eradicate it. Agricultural water saving and rural water resources protection is a major event, which is an important guarantee for the harmonious development of agriculture and rural areas.
Water for industrial production should be saved. Industrial production needs a variety of resources such as venues, equipment and raw materials to support it, but the guarantee condition of industry first is water resources. Industrial production such as thermal power generation, cast steel, petroleum and petrochemical, chemical industry, paper printing, textile printing and dyeing, metal processing, food brewing and other industries all need water. Cooling water, heating water, process water, washing water and other uses are many, and the water consumption is huge. At the same time, it will produce a lot of wastewater, which is the main pollution source of the city. Industrial water is often the main reason for increasing the burden of urban water supply, causing the depletion of groundwater resources and environmental pollution. Water saving in industrial production should be to adjust the layout of planned water industry, so that production can not compete with residents' lives for water and ensure the safety of residents' lives. Develop low-water consumption industrial projects and implement water-saving production processes. Industrial interests cannot harm water resources and the environment. Compared with saving water and protecting the environment, developing production and pursuing benefits cannot attach importance to the former and despise the latter. Don't think that money is something in the bag that can collapse, water can be ignored, and the environment is just something outside. Keep a cool head, ignoring the latter is illegal and criminal! In the production process, it is necessary to carry out sewage purification treatment, reuse of reclaimed water and zero discharge of sewage. Sewage purification and reuse should become an important technical link in industrial production. The matching and operation of these projects will inevitably involve the investment of manpower, material resources and financial resources, which will increase the cost of producing products. In fact, it is the cost composition of the product, which cannot be ignored. However, in some people's previous ideas, the production factors such as water resources and environmental carrying capacity were ignored or even occupied for free. It should be said that people have a cognitive process of industrial water use and water saving, and a process of improvement and improvement of water saving technology. While implementing industrial water-saving laws and regulations, we will vigorously promote advanced water-saving technologies and processes.
Urban management water should be saved. Modern urban municipal construction, environmental sanitation and ecological greening are all inseparable from water, and the water consumption is very large. Streets should be cleaned, toilets should be washed, vegetation should be watered, motor vehicles should be cleaned, pipe networks should be unobstructed, fire water should be guaranteed, landscape water bodies should be maintained, and urban management water is indispensable. If even water cannot be guaranteed, it is not difficult to imagine the function and appearance of a city. Who wants to live in a dirty environment! Urban management uses reclaimed water and rainwater as much as possible. It is necessary to improve and popularize the facilities construction and utilization technology of reclaimed water, and reduce or not use clean water sources as much as possible. Special attention should be paid to protecting groundwater resources in water supply and drainage to prevent sewage from damaging water bodies and the environment. Let the precipitation above the city be effectively used or infiltrated to supplement the underground aquifer, so that the precious water source can circulate in a virtuous circle. In the urban management system, water conservation should be regarded as the fundamental guideline for the coordinated and healthy development of urban modernization and ecological environment.
Save water and ensure water safety. Safety is the main concern of everyone. National defense should be safe, food should be safe, and water resources should also be safe. People need clean water and clean air to ensure their own safety, so water safety must be guaranteed. War may cause damage to water bodies, and wars for water resources are not uncommon in the world. Emerging terrorism is more likely to endanger water security. Plague will destroy the water environment, and human and animal poisoning and food harm caused by water pollution have long been recorded. Sudden water pollution accidents affect people's normal life. Epidemics, natural disasters and earthquakes will destroy the safety of water resources and water supply systems. Groundwater is a relatively safe water source with good water quality and stable reserves, which is not easy to be polluted and has national strategic significance. The safety of water source is related to national security and personal safety. Saving water, especially groundwater resources, is the requirement of water security.
Saving water is an explicit provision of national laws. At the beginning of this century, People's Republic of China (PRC) promulgated the People's Republic of China (PRC) Water Law, which standardized the code of conduct of citizens and governments at all levels in the form of law. In order to rationally develop, utilize, save and protect water resources, prevent and control water disasters, realize the sustainable utilization of water resources, and meet the needs of national economic construction and social development, People's Republic of China (PRC) Water Resources Law is formulated. The State Council and local governments at all levels as well as water affairs, land, health and epidemic prevention departments have also formulated a series of laws and regulations. The core content of many laws and regulations emphasizes water conservation, and "all units and individuals have the obligation to save water", which is clearly stipulated by national laws. Water saving conforms to the national security interests, the requirements of social and economic development, the law of natural ecological balance, and the understanding of the harmony between man and environment.
Article 10 of the Water Law of People's Republic of China (PRC): The State encourages and supports the research, popularization and application of advanced science and technology for the development, utilization, conservation, protection and management of water resources and the prevention and control of water disasters. National laws and regulations have once again clarified the lofty position and leading role of science. The foundation of New China has laid the foundation for national economic construction and social progress, and everything is developing by leaps and bounds. The leading departments, scientific research institutions, professional colleges and production teams of groundwater and environmental management have formed a national system from scratch, from weak to strong, and from top to bottom. The theoretical research and technical practice of water resources, especially groundwater resources, have reached the advanced level in the world. The Institute of Hydrogeology and Environmental Geology, Chinese Academy of Geological Sciences, was the first specialized research institution established by China when New China was founded. A large number of hydrogeologists with academic expertise and rich practical theories have gathered here, serving the main battlefield of the national economy for more than 60 years, and taking groundwater resources and environmental problems in the North China Plain as the focus of research work. As a national scientific research team, it has organized and carried out research work on many topics such as "National Scientific Research Project", "973 Major Scientific Research Project" and "Second Hydrogeological Survey" for many years. Work closely with geological colleagues and local government departments to tackle key problems, constantly push research to depth and breadth, provide theoretical support for government decision-making with research results, and provide technical services for local social and economic development and ecological environment protection. The North China Plain is the region with the highest degree of groundwater development, and it also causes the most problems of resources and environment. The strategic thinking of hydrogeologists is that the sustainable utilization of water resources in North China Plain should respect the natural law of water cycle, make full use of the water storage function of shallow aquifers and make rational use of water resources; Implement inter-basin water transfer project to alleviate the contradiction between supply and demand of water resources in North China Plain and protect and conserve groundwater; Implement the groundwater emergency water supply mechanism to ensure the water supply safety in North China Plain; Make full use of inferior water and rainwater resources to improve water supply capacity; Adjust industrial structure and develop water-saving economy; Strengthen water resources management and strictly plan water use.
Let us work together to create a beautiful plain with beautiful scenery for future generations!
