Saving resources and protecting the environment are two basic national policies based on China's national conditions. China ranks fourth and third in the world in terms of resource reserves and land area respectively. In terms of the total amount, it can be called "vast territory and abundant resources", but in terms of per capita indicators, it is just the opposite. As far as per capita land is concerned, China's per capita is 0.8 hectares, which is only 29% of the world's per capita value; The per capita arable land is 0. 1 1 hectare/person, which is only 40% of the world average; The per capita freshwater resources are only1/4 of the world's per capita; Based on 45 major mineral resources, the per capita mineral resources are less than half of the world's. Specifically, in terms of oil, natural gas, iron ore, copper ore and bauxite, China's per capita mineral resources are only equivalent to the world average of 1 1%, 4.5%, 42%, 18% and 7.3% respectively. Due to the large population in China, the per capita environmental capacity is far below the world average. At the same time, China's resource occupation, consumption and pollutant emission per unit output calculated by GDP and industrial added value are much higher than those in developed countries. Obviously, the economic growth mode of high input, high consumption and high emission is unsustainable.

In order to achieve sustainable development, it is a natural and inevitable choice to take the road of economic development and clean development. Low per capita resources and high consumption of energy and materials make the dependence on foreign countries of many important minerals needed for China's economic development increase. According to the forecast of relevant departments, by 2020, China's dependence on foreign oil will reach 52%, and the dependence on imports of manganese, steel, lead and zinc will reach 38%, 82%, 52% and 69% respectively. At the same time, we haven't really mastered the right to speak in mineral import negotiations, and the import price has increased year by year (for example, the price of imported iron ore increased by 19% in 2005 compared with the previous year, and continued to increase by about 30% in 2006). The rising industrial cost caused by the rising imported raw materials has reduced the competitiveness of China's industrial products in the international market; Under the background of changing international political situation, a series of important mineral products are heavily dependent on imports, which is more related to national economic security. Therefore, economical development and clean development are not only the main contents and inevitable requirements for the implementation of Scientific Outlook on Development, but also the starting point and starting point for promoting the adjustment of economic structure, the transformation of growth mode, and improving the quality and efficiency of growth. The work of saving resources and protecting the environment needs to be carried out at the same time from three levels: country, city and region, enterprise and community. This city plays an important role in connecting the preceding with the following. In terms of cities, it is necessary to implement the two basic national policies of the country and the tasks and requirements of higher-level governments in saving resources and protecting the environment; At the same time, it is necessary to make plans in combination with market conditions, closely integrate conservation and environmental protection with all relevant aspects of urban social development, integrate them into the daily work of urban development, urban construction and urban management, and organize enterprises, administrative institutions and all citizens in the city to implement them.
