1996～2005年来玛纳斯河水质评价及趋势分析

Evaluation and Trend Analysis of Water Quality in Manasi River in Recent Ten Years

通过对玛纳斯河10年来的水质监测资料的研究分析,从中寻找出该流域的地表及地下水质变化规律与发展趋势。结果表明:玛河径流形成区及山前倾斜平原区水质一直保持在1级未受污染级别;山前倾斜平原区地下水中挥发酚以及氮素含量逐年上升,但总体水质仍然保持在1级未受污染级别的范围。

Economic construction level of oasis in arid area was determined by water quality. By analyzing recent ten years＇ data of water quality, the varying tendency of surface water and groundwater in Manasi river valley was found out. The result showed： ①surface water quality in runoff formation area and piedmont clinoplain kept in the range of first-level.②Phenol and nitrogen content in groundwater of piedmont clinoplain were rising yearly, but totally kept in the range of first level.
