| 摘 要： | 利用地理统计学方法对南通市727个无公害农产品生产基地的土壤样点重金属铅含量进行空间分析,拟合半方差函数进行克吕格插值得到铅的空间分布图。发现海门市、启东市、如东县土壤含铅量普遍超过国家土壤含铅量的一级标准,其中海门市土壤含铅量聚集较为显著。其他地区土壤铅含量在国家土壤环境质量标准一级以内。

| Abstract: | 727 soil samples from no-pollution agro- product bases of Nantong city were analysed by spatial techniques,based on the geographical statistics and the ArcGis. We simulated empirical semivariogram and made the current spatial map of soil’s Pb by Kriging interpretation.The results indicated that in considerable area of Haimen city, Qidong city and Rudong county, Pb content in soil exceeded the Pb’s first level of National Standard(35mg/kg), especially the aggregation of Pb in soil in Haimen city was much notable. The Pb content in soil in the other area was within the Pb’s first level of National Standard. |
