摘要
为合理高效利用低丘缓坡土地资源,优化土地配置、解决人地矛盾,以四川省内江市为研究区,构建低丘缓坡土地适宜性评价层次模型,分别采用层次分析法(AHP)和变异系数法(CV)确定评价因子主客观权重,借助GIS空间分析功能和叠加分析法,对研究区进行适宜性评价,将内江市低丘缓坡土地分为高度适宜、一般适宜、勉强适宜和不适宜4个等级,其分别占低丘缓坡土地比例的30.92%,42.40%,22.66%和4.02%.结果表明,全市低丘缓坡土地适宜性处于偏上水平,具有较高发展潜力,适宜开发建设.
In order to use the land resources of low hills and gentle slopes reasonably and efficiently,the scientific basis is provided for optimizing the land allocation and solving the contradiction between men and lands.Taking Neijiang city of Sichuan Province as the research area,a hierarchical model for evaluating the suitability of land in low hills and gentle slopes was constructed,and AHP and CV were used to determine the subjective and objective weight of the evaluation factors.The results show that the suitability of the low hills and gentle slopes of the city is at the upper level,with high development potential and suitable for development and construction.
