青海省平安县供水现状评价

平安县位于青海省东部，是青海省的重要城市之一．通过对青海省平安县平安镇供水现状调查后发现，白沈家沟水源地用于灌溉的机井很多，再加上当地企业自备井长期超量开采，加之气候变化引起降水量的减少，使区域地下水位普遍下降，达不到供水要求，并且管理不善，造成该水源地报废．平安县于2001年起从西宁市自来水公司调水235×10^4m^3／a．根据规划对平安镇的近远期发展用水进行了预测，平安镇近期用水量为2．01×10^4m^3／d，远期用水量为5．30×10^4m^3／d，需要加大从西宁市的调水量以保证平安镇的近期需水要求，远期规划从平安县文祖口水库调水．根据水样检验结果，该水质符合国家饮用水水质标准，适宜人畜饮用．

Ping＇ an County has taken 235 × 10^4 m^3/d water from water supply Company in Xining water demand of Ping＇ an County, which is 2.01 × 10^4 m^3/d city since 2 001. The paper forecasts the future in the near future and 5.30 × 10^4 m^3/d at a specitied future date. Therefore, more water will be taken from Xining city in the short run; while in the long run, the diversion of water from the reservoir of Wen Zu Kou will be implemented.
