Nature is the foundation on which all things live, and human life activities can not be separated from it for a moment. They form a contradictory unity, interacting, interacting and developing with each other, thus forming an ever-changing and colorful human society. As Marx said, "society is the complete and essential unity of man and nature." Ecological environment is an organic whole of nature and a basic condition for human survival and development.

Ecological problem is a "global problem". Since the 1960s, the ecological and environmental problems have become increasingly prominent, followed by the pressure of food, population, natural resources and environmental pollution, which directly affects social and economic development and human survival. Ecological destruction is mainly reflected in species extinction, plant destruction, land degradation and other natural destruction. In the early 1990 s, a famous expert said through textual research: Europe destroyed nature first, then protected nature; The United States destroyed half and protected half; China is being destroyed. Therefore, coordinating the contradiction between economic development, resource utilization and environmental protection has become an urgent problem to be solved in contemporary social development. In China, from Daxing Landscaping to the creation of garden city, from the application of ecological laws to the formulation of ecological environment construction planning, to the proposal and action of ecological city and ecological province, the core is to seek a high degree of harmony between city and nature, and between man and nature. Our city defines the concept of eco-city as: biological resources are effectively protected, natural resources are rationally utilized, environmental pollution is effectively controlled, urban planning and construction are scientific and orderly, economic and social development is coordinated, and man and nature are highly harmonious. From the theory and practice of eco-city, in the final analysis, it actually reflects the requirements of sustainable and harmonious development between man and nature.

First, "harmony between man and nature" and "people-oriented" are the philosophical basis of ecological environment construction.

Huangdi Neijing, a classic work of traditional Chinese medicine, puts forward that "man is related to heaven and earth and corresponds to the sun and the moon." It can be said that the idea of "harmony between man and nature" has penetrated into the production and life of China people in all directions. The relationship between man and nature has always been an active topic for theorists. The dialectical unity of man and nature on the basis of practice is also the basic content of Marx's humanized nature view. Marx said: "Society is the essential unity of man and nature". The essence of Marx's humanized view of nature lies in revealing the essence of the continuous humanization of nature through human's practical activities from the practical point of view, and making man and nature form a dialectical unity relationship of mutual connection, mutual influence and mutual restriction on the basis of practice. On the one hand, people are divorced from nature and opposed to nature; On the other hand, man and nature are closely linked. Without nature, people will lose the possibility of obtaining material means of subsistence and exchanging material, energy and information with nature. In this sense, Marx believes that in productive labor, people are committed to shaping a harmonious "humanized nature". However, due to the existence of alienated labor in society, people have actually become natural destroyers, such as the destruction of natural landscapes, the destruction of biological resources and the pollution of the environment. Therefore, the solution of the contradiction between man and nature depends on the coordination of the relationship between man and nature.

Ecological environment is the basic element of nature, and it is also the hub of the highly harmonious development between man and nature. It has become human knowledge to beautify and improve people's living environment and continuously improve energy conservation and ecological benefits. Taking our city as an example, the practice of harnessing Baier River and creating a garden city proves that ecological gardens and ecological environment show a kind of life and an ideal living environment. It is out of the pursuit of a high degree of harmony between man and nature that contemporary people enthusiastically advocate a moral attitude of loving, respecting and protecting nature and repairing the damaged earth environment through active ecological construction. To this end, the United Nations has promulgated the Agenda 2 1 Century, and China has also formulated the Agenda 2 1 Century, which takes the harmony between man and nature as the philosophical orientation facing the 2 1 century, seeks "efficient, harmonious and sustainable development", and takes the optimization model of green city ecological civilization as the eternal goal of cross-century urban planning strategy.

Second, the construction of ecological environment is inevitable for the sustainable development of man and nature.

The history of human development shows that "politics is a short-term human behavior, which can only be a short moment in the long river of history, but the needs of human ecology are the eternal needs of future generations." The reality of global ecological environment shows that the development of China is under the double pressure of poverty and ecological deterioration, which leads to ecological deterioration and aggravates the poverty army. China's national conditions are: large urban population, rapid population growth, per capita urban construction land resources and artificially increased green space level far lower than developed countries in Europe and America, underdeveloped national economy, late start of modern urban gardens, low starting point, limited investment, and lower overall quality, quantity and level than developed countries. It is urgent to establish new discoveries aimed at the all-round development of human beings and the coordinated development of economy, society, resources and environment. At the same time, the development of ecological gardens has become the need of economic opening and sustainable development.

It is becoming common sense that "planting trees and grass will make the country strong." In order to adapt the ecological environment construction to the requirements of the sustainable development of man and nature, some domestic experts have clearly pointed out that China garden city or "landscape city" with landscape resources as the environmental foundation, landscape culture as the national characteristics, holistic thinking mode and landscape as the urban constituent elements is the development direction of urbanization in China and "a model of urban construction in socialist China in 2 1 century"; It is the concrete embodiment of the strategy of "China Agenda 2 1 century" and "sustainable development of human settlements"; It is an organic combination of Chinese and foreign cultures, and also an organic combination of scientific socialism and China's socialist practice.

The future city should fully reflect the harmony between biosphere and science and technology circle, and the harmony between man and environment. In the relationship between man and the environment, the garden scheme integrating ecology, culture, science and art conforms to the criterion of people's comprehensive demand for the environment. Eco-city construction is a simple way to achieve a high degree of harmony between man and nature. The essence of building an eco-city is to regulate the urban ecosystem, so that the transfer and transformation of urban materials, energy and information can continue. Its goal is to follow the law of urban social function integrity-harmonious ecology-balanced development, change natural disorderly spread into rational distribution, change vicious plunder into maximum utilization, and build a resource allocation mechanism and rational layout with synchronous coordination of economy, society, resources and environment. The ultimate development goal is to realize people-oriented natural transformation and optimization.

Third, building an eco-city is an inevitable choice for the harmonious development of man and nature.

City is a space for people to live and develop, and it is an ecological entity strongly influenced by human activities. From the perspective of eco-city, the city is an artificial ecological complex with human behavior as the leading factor, natural environment as the support, logistics as the carrier, science, education and culture as the driving force and social system as the network, and it is also an open "social-economic-natural complex ecosystem". The proposal of eco-city is based on the theory and method of ecology, which introduces the concept of ecosystem into urban research and embodies the idea of sustainable development between man and nature in the process of urban development.

Shiyan is a mountainous city with a long history of ecological environment construction. As early as 500 years ago, during the Yongle period of the Ming Dynasty, when Judy was in Daxing Mountain, it was clearly stipulated that Wudang Mountain was not allowed to touch a stone and a tree. After 1 1 year, Wudang Mountain formed a Taoist temple complex with a length of 140 Li and a total area of10.6 million square meters, but the ecological environment was not damaged. Later, the Ming Dynasty repeatedly ordered the 800-kilometer mountain forest in Fiona Fang of Wudang Mountain to be included in Taoist temple management and become an ecological protection zone. The History of Qing Dynasty contains ten natural landscapes in Shiyan area. Before the Qing dynasty, the architectural style of the urban area and the greening of this area created picturesque places for people. Before and after liberation, the characteristics of rural greening in urban and rural areas were still very prominent. Since the 1960s, with the "third line" construction and urban development, the ecological environment has experienced the process of destruction, restoration and construction. After 30 years of hard work, our city won the honor of "National Garden City" in 1999, which also deepened people's understanding of the ecological environment, that is, we should not only stay at the level of environmental protection, but also pay attention to handling the relationship between construction and protection from the deep level of the ecosystem.

2 1 century, mankind will turn from pursuing an ancient city with complete functions to pursuing a fresh, green and beautiful environment, which is the result of human consciousness and natural laws. Based on the important role of ecological environment, the strategy of "western development" determined by the CPC Central Committee clearly puts forward that strengthening the protection and construction of ecological environment should be taken as the overall starting point, and the municipal party committee and government of our city have also taken active measures to list our city as a "national ecological construction and environmental protection pilot demonstration zone" and put forward the goal of building an ecological city. No matter from scientific theory or concrete practice, it is of great significance to accelerate the construction of eco-city to play the strategic fulcrum role of Shiyan in the "western development"

The prospect of eco-city should be "green mountains and grass, flowers and birds, fresh air, sky blue and blue water, prosperous economy, civilized and disciplined, and harmonious coexistence between man and nature". & lt/font & gt； It comes down to a high degree of harmony between man and nature, which is an eternal theme. Eco-city construction is a long-term and sustainable social system project, which should first follow the principles of system, ecology, nature and economy. On this basis, we should grasp the following key points:

First, adhere to the value orientation of harmony between man and nature. Only from this philosophical point of view can we promote the formation of a benign eco-city construction and operation mechanism around the principle of "people-oriented" and realize the overall coordinated development. Only by framing its strategic attributes with the optimization model of "efficient, harmonious and sustainable development" can it be possible to build an eco-city. & lt/p & gt；

The second is to change strategic thinking. We must change from the traditional urban development strategy to the coordinated development strategy of urban economy, society and ecological environment. According to objective laws, the indicators of protecting natural resources and improving the quality of ecological environment should be included in the index system of economic and social development. In order to meet the objective requirements of coordinated development strategy in eco-city construction planning, we must also scientifically set economic goals, social goals and ecological environment goals and do a good job of implementation. & lt/p & gt；

The third is guided by the blueprint of optimization planning. To build an eco-city, we must strengthen the target management and control of the ecological environment and fundamentally solve the urban ecological environment problems. We must treat urban development with ecological laws. When formulating urban economic and social development issues, we should consider both economic laws and ecological laws. At the same time, the revision of urban master plan must emphasize the importance of environmental protection and ecological balance, embody characteristics, and concretize the goals and measures to improve urban ecological environment, and regard it as a basic task of modern urban construction. & lt/p & gt；

Fourth, we should properly handle the relationship between ecological benefits, social benefits and economic benefits, short-term benefits and long-term benefits, local interests and overall interests, construction and protection, and construction and development. Especially with the establishment and development of market economy system, economic means are playing an increasingly important role in urban development, and it is urgent to formulate eco-environmental economic policies that are coordinated with urban economy. & lt/p & gt；

Fifth, establish and improve an effective legal system for ecological environment and strengthen environmental management. We should learn from the beneficial experience of developed countries that "economy depends on the market and ecological protection depends on the government". It is necessary to strengthen the formulation and implementation of urban environmental management laws and regulations, so as to ensure that there are laws to follow, laws to be obeyed, law enforcement to be strict, and the combination of law enforcement and supervision to provide an important guarantee for the construction of eco-cities. & lt/p & gt；

Sixth, strengthen environmental education and constantly improve the environmental awareness of the whole people. We should establish an environmental and ecological education system with China characteristics, so as to enhance the awareness of ecological and environmental crisis, popularize environmental and ecological knowledge and improve the ecological and cultural foundation of the whole nation. Ecological environmental protection should form a social fashion that everyone is responsible for and pay close attention to the management of * * *, establish a new concept of respecting the laws of nature, cherishing natural resources, caring for the ecological environment and living in harmony with nature, and strive to provide a fundamental guarantee for building an ecological city and protecting the ecological environment.
