Evaluation of Surface Environment Quality in Chenzhou Prefecture

利用郴州地区１：２０００００区域地球化学水系沉积物测量资料，选择Ｐｂ、Ａｓ、Ｃｒ，Ｈｇ、Ｆ、Ｃｕ、Ｚｎ元素作为污染评价因子，对区内地表环境质量进行分析评价，划分出５类不同级别的污染分区及含量标准，为该区制定防污措施、控制环境污染、保护生态环境提供了资料依据。

According to the 1:200000 regional stream sediment geochemical survey data in Chenzhou pre-fecture,take pb.As,Cr,Hg,F,Cu.Zn as contamination-estimating factors to evaluate the surface environ-ment quality of the area。 Five classes of contarnination sub-area and their standards of element contents are de-termined. which provided data basis for working out pollution-preventing measures,controlling environrnental pollution and protecting the ecological environment.
