摘要
[目的]运用地理信息系统监测与评价农业土壤环境状况。[方法]以余干县为例，将数据空间统计方法与模糊综合评价法融入农业地质环境监测方法中，运用ArcGIS 10．2软件分析了土壤养分分布情况。[结果]余干县表层95．32％的面积土壤为一类土壤（未被污染土壤），4．68％的面积为二类土壤（轻度污染土壤），土壤整体上缺乏速效钾。[结论]地理信息技术为农业地质环境监测与评价提供了新方法。
Abstract
Objective] To monitor and evaluate the agricultural soil environment status by Geographic Information System.[Method] With Yugan County as a case, spatial statistic method and fuzzy comprehensive evaluation method were integrated into the agricultural geological en-vironment monitoring method.ArcGIS10.2 software was used to analyze the nutrient distribution in soil.[Result] 95.32%surface area of soil in Yugan County belonged to first-grade soil ( not polluted);4 .68% area was second-grade soil( slightly polluted) .Soil was lack of rapidly a-vailable potassium in Yugan County.[Conclusion] Geographic Information System provides new method for the monitoring and evaluation of agricultural geological environment.
