City planning implemented ecological security post-evaluation method

Abstract

The invention discloses a city planning implemented ecological security post-evaluation method. The method comprises the following steps of: S1, establishing a comprehensive evaluation index system comprising each index factor which represents a socio-economic factor, a natural ecological factor and an ecological human response factor respectively; S2, performing standardization processing on the index factors according to different sources and characters of index data; S3, generating a spatial data-index standardization layer according to the index factors subjected to the standardization processing; and S4, determining the weight of each index factor and calculating a composite index to obtain a comprehensive evaluation result. The city planning implemented ecological security post-evaluation method has the advantages of improving the city ecological security evaluation and planning system, enhancing the continuity and systematicness, performing visualized processing on the evaluation result by combining relative software and realizing the combination of city ecological planning system regulation and spatial regulation.

Description

technical field [0001] The invention relates to the fields of environmental science and urban ecological planning, in particular to a post-evaluation method for ecological security in the implementation of urban planning. Background technique [0002] Western developed countries have experienced various environmental problems in the process of urbanization earlier. In order to get rid of the vicious circle of disorderly urbanization and ecological decline, European and American countries have successively carried out ecological regulation attempts for the purpose of promoting the integration of cities and nature. Putting it into urban planning practice, such as the early conception of "Garden City", the construction of the green belt around London, the idea of ​​"Green City", the green corridor movement, and green infrastructure, all of which have had a profound impact on the world's urban development model . In the practice of promoting the optimal use of land and reducing...

Problems solved by technology

However, the above two inventions only involve traffic and road systems, and fail to fully consider social, economic, and environmental factors. Moreover, these two inventions have high investment costs and are difficult to implement, and cannot effectively solve the existing serious problems of urban ecological security.
