喀喇昆仑山地区地表水资源特征及饮用条件

Surface Water Characteristics and Drinking Conditions in the Karakoram Mountains region

通过资料汇总、现场调查、取样试验、类比分析等手段,对区域内冰川雪水、河流水、湖泊水等地表水资源分布特征、水质条件进行研究。该区域地表水资源主要以降雪或融雪补给为主,冰川雪水水质状况较好,河水水质状况相对较差,湖泊水水质状况最差。因生活需要,采用冰川雪水、河流水、湖泊水为饮用水源时,对冰川雪水可经简单净化处理后即可符合饮用水源条件,河流水与湖泊水则需根据实际情况加大净水措施。

By means of data collection,field investigation,sampling test and analogy analysis,the distribution character-istics and water quality conditions of glacier snow water,river water and lake water in the region were studied.It is found that the surface water resources in this region are mainly supplied by snowfall or snowmelt,and the water quality of glacier snow water is good,river water quality is relatively poor,and lake water quality is the worst.If glacier snow water,river water and lake water are required to be used as drinking water sources due to living needs,the glacier snow water shall meet drinking water sources conditions after simple purification treatment.For river water and lake water,wa-ter purification measures shall be strengthened according to the actual situation.
