塔里木盆地南缘和田地区生活用水地下水质分析

干旱区水资源短缺，生产用水、生态用水与人民群众的生活用水矛盾突出。针对和田地区农村改水的地下饮用水状况的分析和评价，结果表明，地下饮用水的色度、浑浊度以及砷、泵、镉、铬、铅、硝酸盐等超标率均为零。总硬度、Cl^-、SO4^2-及F^-等指标的超标率较高，而这些物质的存在对于水质的理化性状影响较大，并因此而引发人体健康教育改变。和田地区总体饮用I级水的人口数量多，但局部的超标水依然存在。应通过对区域自然地理状况和人文因素的系统研究和科学论证，加强水源保护，改进卫生条件和卫生观念，建立农村饮水监测网，加强系统监测、监督和管理，以保障人民群众安全的生活用水。

Quality Analysis for Life Water Demand of Groundwater in Hotan Area

It is lack of water resource in arid zone.The contradiction among production water demand?ecological water demand and life water demand are very seriously.Based on the groundwater analysis and assessment during the drinkable life water improvement in Hotan area,the results are as follows,some composition have no over standard rates,such as,chroma,muddy degree and arsenic?mercury?cadmium?chromium?lead and nitric acid salts,etc.In contrast,hardness of water,Cl -?SO 4 2- and F - have high contents over the standard,which have important influence on physical and chemical features of water quality. Moreover,it is probably caused humans healthy effects.in generally,most of people drink the first-degree water quality in Hotan.But water quality that is over standard in part of areas is also in existence.in order to build up monitoring net of drinking water in the villages,it should depend on the systematic research and scientific proof of regional physical geography condition and artificial factors.Meanwhile,strengthening water protection and improving healthy conditions and views also should be taken.In a word,it is necessary to emphasis on systematic supervisor and management so as to ensure people safe life water.
