摘要
通过GIS的空间分析以及主成份分析,对泸西县农业用地适宜性进行评价与分析。确定了该县农用地适宜性评价的参评因子及其影响度(隶属度),建立了适宜性评价指标与分类体系,划分农业用地适宜性等级,编绘农业适宜性等级图,为科学规划、合理利用、有效保护土地资源,促进可持续发展提供依据。
In this paper,a study on evaluation and analysis for agricultural land suitability in Luxi county of Yunnan province has been done by using GIS spatial analysis and principal component analysis.The evaluation factors and their impact degree(membership degree)for the suitability of agricultural land in the county have been determined,and suitability evaluation indicators and classification systems have been established.The suitability level of agricultural land has been divided,and an agricultural suitability level map has been compiled to provide a basis for scientific planning,rational utilization,effective protection of land resources,and promotion of sustainable development.
