| 摘 要： | 采用网格分区法在巢湖周边地区设置了60个采样单元,采取表层土样分析了总氮(TN)、有机质(OM)的空间分布特征。结果表明:(1)表层土壤w(TN)平均值为1 027 mg/kg,变化范围253 mg/kg~2 273 mg/kg,变异系数为46.3%;w(OM)平均值为1.95%,变化范围0.291%~5.48%,变异系数为49.3%。(2)表层土壤w(TN)、w(OM)高浓度地区主要集中在东部的柘皋河、兆河区域,低浓度地区主要集中在西部的派河、南淝河—店埠河区域。(3)巢湖周边地区土壤总氮、有机质空间分布与区域内入湖河流、巢湖水质、巢湖沉积物污染空间分布不一致。

| Abstract: | The concentration of total nitrogen(TN) and organic material(OM) at 60grid divisions in Lake Chaohu basin were studied to investigate their spatial distribution characteristics.Results showed that average concentrations of TN and OM were 1,027 mg/kg,1.95% and their concentrations ranged from 253 mg/kg to 2,273 mg/kg and 0.291% to 5.48% respectively.High concentration areas were located at the basin of Tuogao River and Zhao River in east part while low concentration areas were located at basins of Pai River,... |
