Karst region territorial space development suitability evaluation method and system

Abstract

The invention discloses a karst region territorial space development suitability evaluation method and system, and the method comprises the steps: building a territorial space development suitabilityevaluation index system of a karst region, wherein first-level indexes comprise resources, environments, disasters and ecology, each first-level index comprises a plurality of second-level indexes, and the resources comprise agricultural production conditions, urban construction conditions and water resources, the environment comprises agricultural production environment conditions and urban construction environment conditions, the disasters comprise agricultural meteorological disasters and geological disasters, and the ecology comprises ecosystem service and ecological sensitivity; decomposing each second-level index into a plurality of third-level indexes; determining the weight of each three-level evaluation index by using an expert scoring method, and performing weighted average by using a comprehensive index method to obtain an evaluation result of each two-level index; and calculating an agricultural production suitability evaluation result, an urban construction suitability evaluation result and an ecological protection importance evaluation result according to each secondary index evaluation result.

Description

technical field [0001] The invention relates to the field of land space planning, in particular to a method and system for evaluating the suitability of land space development in karst areas. Background technique [0002] Land space planning is an important starting point for implementing the strategy of main functional areas and drawing a blueprint for a beautiful future land. The suitability evaluation of national land space development is the premise and foundation of national land space planning. The concept of land space development and construction suitability originated from the idea of ​​land suitability. The evaluation index system was mainly based on engineering geological conditions in the early stage, and then involved elements became more and more diversified, covering geological landforms, ecology, economy, and society. Scholars at home and abroad have used methods such as multi-element spatial overlay analysis, landscape pattern analysis, ecological niche mod...
