Ecological network construction method based on ecological service logic coding

Abstract

The invention provides an ecological network construction method based on ecological service logic coding, and the method comprises the steps: S1, building a factor evaluation mechanism, and selectingfactors which comprise ecological service factors and human interference factors; S2, grading the selected ecological service factors; S3, introducing logic codes to establish an ecological service logic coding model, and making an ecological service logic map according to a model calculation result; S4, introducing a human interference factor improved resistance surface model, and establishing ahuman interference factor model; s5, identifying the ecological corridor by using the minimum cumulative resistance model in combination with the ecological source land and the resistance surface; and S6, establishing an ecological service coupling gravity model for evaluating the identified ecological corridor and constructing an ecological network. The ecological network construction method based on ecological service logic coding not only provides a new research framework for researching the ecological network, but also provides scientific guidance for ecological protection and planning.

Description

Technical field [0001] The invention belongs to the technical field of ecological environment research, and particularly relates to an ecological network construction method based on ecological service logic coding. Background technique [0002] In recent years, the construction of ecological network has become one of the hot issues in landscape ecology research. The basis of ecological network construction is to determine the ecological source. The ecological source is the origin of species diffusion and maintenance, and is a landscape component that promotes the development of ecological processes. However, the existing research on the relationship between the ecological source and the spatial pattern of ecological services is lacking when identifying ecological sources, the study of the map relationship between the types of ecological services corresponding to the ecological source, and the importance of the ecological source according to ecological services. Research on the r...

Problems solved by technology

However, when identifying ecological source areas, there is still a lack of research on the relationship between ecological source areas and their ecological service spatial patterns, research on the map relationship between ecological source areas corresponding to ecological service types, and identification of the importance of ecological source areas based on ecological services. At present, in the research of map relationship, too few factors are considered in the process of ecological network construction, and the framework of ecological network construction is relatively simple
