Research on Land Use Change and sustainable use in Karst areas——with special reference to Guiyang city in Guizhou province

以贵阳市为研究区域,在分析土地利用变化的基础上,从资源保护性、生态合理性、经济可行性、社会接受性等方面构建土地可持续利用指标体系。通过土地可持续利用综合评价模型和土地可持续利用障碍因素诊断模型,评价贵阳市土地可持续利用水平,分析其土地可持续利用的障碍因素,并提出相应的对策。

Using Guiyang city as research area, the index system was constructed from some aspects of the resources protection of sustainable use, the ecological rationality of sustainable use, the economical feasibility of sustainable use, the social acceptability of sustainable use on the basis of analysing land use change. The level of sustainable land use was assessed by the overal evaluation model of sustainable land use and the impedient factors of sustainable land use was analyzed by the diagnostic model of the impedient factors of sustainable land use. The countermeasures for sustainable land use in Guiyang city are proposed in the paper.
