主要城市饮用水水源地水质状况评价与对策建议

１９８９年对全国４９个环境保护重点城市的８１个饮用水地表面水源和３０个饮用水地下水源保护情况调查表明，４８％的地表水源、２０％的地下水源达到相应标准；１９９６年调查结果表明，２０４个地级以上城市的３２９个饮用水地表水源和２４２个饮用水地下水源中，这一数字已分别上升到８３．３％和２７．７％。其可比的２０个重点城市的３９个水源地水质监测结果表明：１９８９－１９９６年间，饮用水源地水质呈恶化趋势，在评价

Drinking Water Resource Quality Evaluation and Countermeasures of Main Cities

Based on the investigation of 49 cities in 1989 and 204 cities in 1996, the assessment of drinking water resource quality was carried out. It is shown that only 48% of 81 surface water resources and 20% of 30 ground water resources can not meet with the restactively in 1989. However, 83.3% of 329 surface water resources and 27.7% of 242 ground water resources can not meet with the standard in 1996. By comparing and analyzing the data of 39 water resources in 20 environmental key protection cities in 1989 and 1996, there has been a decreasing trend of drinking water quality. Finally the countermeasures and suggestions on protecting the environment of drinking water resource is put forward.
