新疆地表水资源质量及变化趋势分析

Analysis of Quality and Trend of Surface Water Resources in Xinjiang

根据实测资料对新疆主要河流和湖泊、水库的天然水化学特征及水资源质量现状进行了分析。在多年监测资料的基础上选择能反映新疆主要河流水质特点的水质参数 ,采用剔除了水质浓度受流量季节性影响的肯达尔非参数检验方法 ,对新疆主要河流 1993～ 2 0 0 0年间的水质变化趋势进行了定性、定量分析 ,对污染产生的原因进行了分析 ,提出了防止水污染的对策与建议。

This article assesses the quality of surface water resources in Xinjing through in terms of the current quality, trends of the changes. The study on water quality at 65 major river sections of 40 main rivers in Xinjiang shows that, 91.7% of the monitored river section totaling 6 079.5km in length is up to the Class 3 level of surface water quality standard and thus can meet quality requirements for industrial, agricultural, fishery, domestic water uses, etc., while 8.3% of the monitored river section is polluted. Due to pollution by the area sources, water quality of some of the rivers indicates the degradation tendency. Analyses of the 39 river sections of 28 major rivers and of 2 reservoirs using Kenduer Non parameter Test Method .show that, in the period from 1993 to 2000, water quality of 57% of the rivers was degrading, and salt pollution of Tarim River was increasing.
