摘要
在GIS技术系统的支持下 ,以土壤肥力因子为基础 ,运用相关分析、层次分析和模糊评价等数学方法和数学模型 ,对苏州地区的水田质量进行了定量化和科学性的评价。评价中充分利用了GIS软件处理空间数据和属性数据的强大功能 ,评价结果基本符合当地的实际情况 。
The evaluation of land quality plays an important role in land use plannin g. In this paper, a quantitative and scientific evaluation of land quality based on GIS was made. Mathematical models, such as correlation analysis, hierarchica l analysis, fuzzy evaluation, were applied in this study. The evaluation results accorded with the actual state of Suzhou, which indicated that this technique w as feasible and scientific in land evaluation.;
