孔雀河中下游河水化学性质变化规律及其影响分析

Chemistry Property and Variety Regulation and the Affects of the Peacock River

在干旱地区，节水与防止水资源污染同等重要，我们于2001年6月-2003年12月对孔雀河水质进行监测，每月15日取样观测一次。经过分析数据得出：河水符合生活用水标准和农田灌溉水标准占52．8％。通过对河水水质的年变化规律分析得出：引起孔雀河水盐分含量增高的主要因素为上游的排水、排盐，其次为河水源头“博斯腾湖”水盐分含量比较高。与其它内陆干旱河流相比，排水、排盐是引起河水盐分增加的共同点，而河水浓缩致使盐分含量增加在孔雀河中游表现不明显，河水源头盐分含量比较高为其特征，望在塔里木河治理中引起重视。

It is equally important that saving water and preventing water being polluted in arid region. We carried on the monitoring to the Kongque River water quality in 15th of each month from June, 2001 to December, 2003. The results showed that the river water accounts for 52.8% which conforms to the domestic water standard and the farmland irrigation water standard. The analysis of annual river quality variation showed that the primary factor which caused Kongque River water salinity to increase main for upstream draining saltwater. Compared with other rivers of arid region,draining water and salt are the common characteristics which causes the river water salinity increases. However, salinity increase in the middle reaches of Kongque River is not obvious. The high salinity in river water source should be pay atention in Tarim River harness.
