摘要
博斯腾湖水质恶化和湿地生态系统退化严重影响博斯腾湖流域的地区发展。研究通过系统聚类法和综合污染指数法,对博斯腾湖2005-2007年入湖水质指标进行综合分析与评价。结果表明,2005-2007年综合污染指数有所下降,水环境质量略有改善;近三年影响博斯腾湖水质的主要影响因子是溶解性总固体、硫酸盐和氯化物,对水体污染的贡献最大,应继续加大农田排水和入湖河流的质量管理。
The development of the Bosten Lake basin will be adversely affected by its water quality deterioration and wetland ecosystem degenerated. Based on the water quality data of the rivers flowing the Bosten Lake from 2005 to 2007, combining methods of system analye and comprehensive pollution index were used to analysis and evaluate the water quality of the Bosten lake. The results indicated that, the synthesis pollution index had decreased from 2005 to 2007, and the water quality had improved slightly. Solubility total solids, sulfate and chloride were major factors affecting the water quality in the latest 3 years. The measures were put forward to control water quality of agricultural drainage and rivers which flow into the lake.
