广西土地综合承载力评价研究

土地综合承载力是资源环境承载力的重要组成部分,对区域协调发展具有重要意义.该研究根据土地综合承栽力内涵,选取水土、经济、社会、生态等方面指标,运用层次分析法、多指标综合评价法和聚类分析法,构建评价指标体系,计算广西各地市土地综合承栽力评价值,并根据此评价值将广西划分为5种类型区,即高承载区、较高承载区、中等承载区、较低承栽区、低承栽区.在对评价结果进行分析的基础上,提出合理性建议,为广西国土规划利用和管理提供参考.

Study on Land Comprehensive Carrying Capacity Evaluation of Guangxi Zhuang Autonomous Region

Land comprehensive carrying capacity is an important part of resource and environment carrying capacity,has significance on regional coordinated development.Based on the concept of land comprehensive carrying capacity,selecting indicators of water and soil,economy,society and ecology,an evaluation index system was constructed by using AHP,cluster analysis and the multi-objective comprehensive evaluation methods.The land comprehensive carrying capacity of Guangxi was evaluated.Then,based on the evaluation value,land comprehensive carrying capacity of Guangxi can be divided into five types,namely the high carrying capacity subregion,the higher-level carrying capacity subregion,the mid-level carrying capacity subregion,the lower-level carrying capacity subregion,the low carrying capacity subregion;and on the basis of comprehensive analysis of the evaluation results,several suggestions were put forward,which can provide reference for land planning and management of Guangxi.
