    A New Method for Determining Evaluation Units and Obtaining EvaluationData in GIS-Based Land Resource Evaluation

      摘要
    • 摘要: 该文提出了在基于地理信息系统（ＧＩＳ）的土地资源评价中，以土地资源类型作为评价单元，将土地资源类型图与各个评价因子的单要素图层分别进行了叠置分析，通过对各生成图层的ＰＡＴ文件进行操作来获取评价数据的新思路。并在基于ＧＩＳ的浙江省坡地土壤资源质量评价中作了初步应用。对传统的及基于ＧＩＳ的土地资源评价中确定评价单元的各种基本方法进行了分析和比较。

       

      Abstract: A new methed in GIS-based land resource evaluation of overlaying the coverage of land re-source type map separately with single-factor-coverages of each evaluation factor and obtaining basic datafor evaluation by operating the polygon attribute table (PAT) of each resulted coverage was advanced,and its advantages compared with traditional methods was pointed out.
