An ecological protection red line delineation method, device, terminal equipment and storage medium

Abstract

The invention discloses a method, device, terminal equipment and storage medium for delimiting ecological protection red lines. The method includes: obtaining land use change results, ecological service value evolution results and landscape based on historical land use data of the area to be delineated Spatio-temporal evolution results of the pattern index; according to the above obtained results, firstly select the ecological sources of the area to be demarcated, then generate the ecological source resistance surface of the ecological sources, and obtain the initial demarcation results of the ecological protection red line; according to the land use history Data, use the first prediction model to obtain the future demand of the land use type of the area to be delineated; according to the future demand, use the second prediction model to obtain the future land use data of the land use type of the area to be delineated; according to the initial delineation The results and future land use data are used to obtain the final delineation results of the ecological protection red line. The invention can obtain the ecological protection red line with high precision and fine boundary.

Description

technical field [0001] The present invention relates to the technical field of geographic information, in particular to a method, device, terminal equipment and computer-readable storage medium for delimiting ecological protection red lines. Background technique [0002] As the rigid constraint area of ​​ecological space, the ecological protection red line is an important part of the "three districts and three lines" (town, agriculture, ecological space, as well as the ecological protection red line, permanent basic farmland, and urban development boundary). System service functions and an important measure to build an ecological security pattern. [0003] The current common method of delineating ecological protection red lines is usually guided by the "Guidelines for the Delineation of Ecological Protection Red Lines", which is only divided at the provincial or county level, and the quantitative indicators considered in the process of delineating ecological protection red l...

AI Technical Summary

Problems solved by technology

[0004] The present invention provides a method, device, terminal equipment and storage medium for delineating the red line of ecological protection, in order to solve the technical problems of low accuracy and rough boundaries of the red line of ecological protection delimited by the existing method, and by treating the delineated area Analyze the historical land use data, set quantitative indicators according to the analysis results, and use the Markov model and PLUS model to predict the future land use data of the area to be demarcated, and can obtain high-precision and fine-boundary ecology based on the predicted results protect the red line
