Abstract: Ecology, planning, science

Guided by the principles of ecology and urban-rural planning, it is a plan to identify, simulate and design various ecological relationships in the artificial composite ecosystem, determine the ecological suitability of resource development, utilization and protection, explore ecological construction countermeasures to improve the structure and function of the system, and promote the sustainable and coordinated development of the relationship between man and environment.

Edit the main points of this part of the plan.

According to the principles of ecological economics, combined with the national economic development plan, a long-term plan to realize and protect ecological balance is formulated. Its purpose is to make rational and effective use of various natural resources through planning to meet the growing social production and consumption needs; At the same time, ensure that the survival activities of human society do not hinder and are conducive to giving full play to the functions of nature, so as to maintain and enhance the regenerative capacity of natural resources and natural environment. Ecological planning is a comprehensive planning that balances human production, non-production activities and natural ecology. Generally, it includes: ① plans and measures to ensure the sustainable recovery, steady growth, quality improvement and sustainable utilization of renewable resources. (2) Plans and measures to protect the biological integrity of natural systems, such as prohibiting overfishing of wild animals, collecting wild plants rationally, establishing nature reserves, protecting rare wild animals and saving endangered species. ③ Plans and measures for rational and effective utilization of non-renewable resources such as land, minerals, energy and water, so as to increase the economic value of natural systems. ④ Plans and measures for pollution control and prevention. ⑤ Plans and measures to improve human environmental quality, so as to enhance human physical and mental health and protect the aesthetic value of human living environment. Ecological planning is divided into national, regional and local ecological planning according to different levels; According to different types, it can be divided into urban ecological planning and rural ecological planning. When making ecological planning, we should study and determine the local ecological construction indicators according to the natural, economic, social conditions and pollution conditions of the country, region or local area, ensure that the development and utilization of resources do not exceed the resource potential of the region, do not reduce its use efficiency, ensure that economic development and human survival activities adapt to the ecological balance, and make the natural environment not undergo drastic destructive changes. The indicators of ecological construction include: dividing the reasonable proportion of urban and rural land resources; Divide the proportion of factories, roads and residential land in the city; Divide the proportion of farmland, gardens, roads and houses in rural areas; Determine the quantitative indicators of population capacity, resource utilization, economic development scale and living facilities.
