Abstract

The invention provides a method and a medium for extracting land ecological value index of spatial expansion of urban agglomeration. The method includes: acquiring the spatial data of land use / land cover in Coverage format from the database of urban agglomeration by using GIS technology, and preprocessing the spatial data; Loading a calculation model from a calculation model base, and calculatingan ecological value index of different land types of the urban agglomeration region in the study period by using the loaded calculation model and the spatial data; Chart exporting ecological value indices. The invention solves the problem that an effective solution is not provided for the study of the influence mechanism between the spatial expansion of the urban agglomeration and the ecological environment in the related technology, and not only provides a method capable of effectively studying the influence mechanism between the spatial expansion of the urban agglomeration and the ecologicalenvironment, but also improves the research efficiency.

Description

technical field [0001] The present invention relates to the field of data processing, in particular to a method and medium for extracting land use ecological value index for spatial expansion of urban agglomeration regions. Background technique [0002] The spatial expansion of urban agglomerations and other regions includes two aspects: the spatial expansion of urban land and the interactive replacement of ecological land. The spatial expansion of urban land use will inevitably lead to changes in ecological land use, and the interactive replacement of ecological land use will inevitably have an impact on the ecological environment of urban agglomerations. How to regulate the reasonable degree and extent of this impact requires an analysis of the impact mechanism between the spatial expansion of urban agglomerations and the ecological environment. [0003] In related technologies, no effective solution has been proposed for the research on the mechanism of influence between...
