Ecological resource bearing model method for urban and rural ecological planning

Abstract

The invention discloses a method for quantitative partitioning by an ecological resource bearing model, which comprises the following steps: carrying out investigation and survey in a target area, and carrying out GIS (geographical information sciences) vectorization on results, establishing a unified coordinate system, and drawing the coordinate system into thematic maps; respectively grading by using preset classification standards; respectively calculating weight values by using an analytic hierarchy process; carrying out mutual superposition and merging on the thematic maps by using the GIS; and carrying out weighted averaging on single factors of water resources, single factors of land resources, single factors of forestry resources and single factors of mineral resources so as to obtain analysis results of an ecological resource bearing model, thereby completing the quantitative partitioning on the target area. According to the invention, the information in each aspect of ecological resources is integrally superposed through the GIS, and through optimizing the analytic hierarchy process and establishing a quantitative evaluation system, the inherent conditions of ecological resource bearing are expected to be studied simply and comprehensively, and implemented to the spatial publishing of urban planning.

Description

technical field [0001] The invention relates to a method for quantitative partitioning by using an ecological resource bearing model. Background technique [0002] The ecological resource carrying model method is a spatial ecological analysis method specifically aimed at the capacity of various ecological resource systems in the ecosystem in urban and rural ecological planning, and is used to judge the status quo of resource utilization in urban and rural ecological planning. The resource carrying index measures the level of resource capacity that the supply of various natural resources in the ecosystem can provide for human development on a sustainable and balanced basis. The size of the carrying capacity of resources depends directly on the way and means of resource utilization. Different utilization methods will have different consequences. Resource carrying capacity selects water environment, land resources, forestry resources, mineral resources, and tourism resources a...

Problems solved by technology

[0005] The advantages and disadvantages of objective weighting methods (principal component analysis, factor analysis, gray relational method and entropy value method), and think that the use of subjective weighting method is mixed with the subjective arbitrariness of decision makers, while the use of objective weighting method Lack of willingness of decision makers

[0006] Defects of existing technical solutions: for urban planning and construction, it is necessary to comprehensively reflect the status of regional ecological resources, not only to evaluate its ecological resources, but also to evaluate the operability of urban planning practitioners and how to implement them into urban planning.
