| 摘 要： | 以广东省东莞赤红壤农业现代化实验区为例，在地理信息系统（GIS）技术和数学模型的支持下，应用AcrInfo进行空间数据采取、处理与分析，采用叠置分析的方法，以评价因素的组合确定评价单元；采用层次分析法确定评价因素的权重，在对评价标准进行模糊化处理后，建立变权评价模型进行土壤质量评价，应用ArcView GIS绘制了评价结果图，并对变权评价结果与常权评价结果进行了比较与分析，结果证明，采用变权模型进行土壤质量评价，比常权评价更能反映土壤质量的实际情况。 |
| 关 键 词： | 地理信息系统 土壤质量 评价 变权模型 模糊变权评价 |

| Abstract: | Based on the technique of Geographic Information System and mathematical models, Dongguan Agricultural Modernization Experimental Field for Red Soil Areas was taken as the research site for soil quality evaluation.ArcInfo was adopted to data processing, and overlay analysis to spatial data analysis.Evaluation units were determined by combination of evaluation factors.AHP was applied to judge the weight of each evaluation factor.After evaluation criteria was fuzzified, variable weight evaluation was carried out.The results were calculated and mapped by using ArcView GIS software.Dif ference between results from evaluation with variable and constant weight was compared and analyzed.Results show that soil quality evaluation with variable weight is better than with constant weight. |
| Keywords: | Geographic Information System (GIS) Soil quality Evaluation Vari-able weight |
