地球化学资料在区域生态环境评价中的应用

Geochemical data were applied in the assessment of regional ecological environment

研究以水系沉积物样品为研究对象,应用指数法对研究区进行了生态环境评估,结果表明,研究区总体上是一个清洁的尚未污染的地区,为农、牧、林业的规划提供了基础的地球化学资料。

In this paper, we assessed ecological environment in the study area by the index method, tacking stream sediment samples as the research subjects. The results show that： We deemed the study area was a clean areas generally, that provided the basis geochemical data to local government for programming the agriculture, herding and forestry.
