| 摘 要： | 基于ArcGIS地统计分析模块,以三峡库区消落区为研究区域,对忠县环城区消落带、忠县石宝镇干支流消落带、万州长江干支流消落带、万州新田干流消落带等土壤中重金属Cu含量水平和空间分布特征进行了研究,研究表明：典型消落区重金属Cu含量范围为16.33～74.81 mg/kg,最高值为最低值的4.58倍,其算术平均值为33.14 mg/kg,标准差为12.676.利用GIS技术研究了重金属Cu方向分布趋势和空间分布格局. |

| Abstract: | Based on the statistical analysis module of ArcGIS,heavy metal contents Cu and their characteristics of spatial distribution are studied in water level fluctuating zone of Three Gorges reservoir,such as the zone along Zhong County,the zone of branch river of Shibao town,Zhong County etc.The hotspots of Cu pollution which indicate higher risk than other areas are identified to be mainly distributed in the water-level-fluctuating zone of soils near populated areas along the Xiao River.The mean content of Cu i... |
