Urban and rural integrated ecological security pattern construction method

Abstract

The invention relates to the technical field of ecological safety pattern construction, in particular to an urban and rural integrated ecological safety pattern construction method. The construction method comprises the following steps: determining a research target and collecting data, classifying urban and rural landscape types, establishing a model and constructing a spatial distribution diagram, evaluating an ecological safety risk, constructing an ecological safety pattern, applying an ecological safety pattern resistance model and optimizing a comprehensive ecological safety pattern. According to the method, a unified systematic pattern construction method is adopted, use of workers is facilitated, the constructed framework is clear, a relation model between the environment variables and the ecological safety pattern is directly established, the problem that a large amount of transition data is generated in an existing method is avoided. Compared with the prior art, the method has the advantages that the ecological safety pattern of each region can be constructed more objectively and scientifically, and the method has better reference value in practical use.

Description

technical field [0001] The invention relates to the technical field of ecological security pattern construction, in particular to a method for constructing an urban-rural integrated ecological security pattern. Background technique [0002] Although through long-term and unremitting efforts, great achievements have been made in the construction and protection of my country's ecological environment, the situation is still very grim. The problem of structural damage to the ecosystem is becoming more and more prominent, and the ecological function is showing a trend of continuous degradation, the degree of ecological degradation is intensifying, and the ecological service function is declining. At the same time, a series of ecological and environmental problems caused by land degradation, industrialization, urbanization and mining development have become increasingly prominent, biodiversity has been continuously reduced, water resources have become increasingly scarce, and the ...

AI Technical Summary

Problems solved by technology

[0004] In the construction of the ecological security pattern, people do not have a good understanding of urban and rural ecological security and its ecological security pattern. At present, the ecological security pattern predicted by the constructed ecological security pattern model is relatively low in scientificity. In practical applications, refer to value is limited
