Ecological protection red line delimiting method and device, terminal equipment and storage medium

Abstract

The invention discloses an ecological protection red line delimiting method and device, terminal equipment and a storage medium, and the method comprises the steps: obtaining a land utilization change result, an ecological service value evolution result and a space-time evolution result of a landscape pattern index based on the land utilization historical data of a to-be-delimited region; according to the obtained result, firstly selecting an ecological source land of the to-be-delimited area, then generating an ecological source resistance surface of the ecological source land, and obtaining an initial delimiting result of the ecological protection red line; according to the land utilization historical data, using a first prediction model to obtain the future demand of the land utilization type of the to-be-delimited region; according to the future demand quantity, by utilizing a second prediction model, obtaining future land utilization data of the land utilization type of the to-be-delimited region; and obtaining a final delineation result of the ecological protection red line according to the initial delineation result and future land utilization data. According to the invention, the ecological protection red line with high precision and fine boundary can be obtained.

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
