[目的 ]探讨山区水库的预防性审查与环境处理 ,为今后工作提供指导。 [方法 ]对 3个水库蓄水前后的疾病和水质变化情况进行比较研究。 [结果 ]水库蓄水后对周围人群健康未造成影响 ,水库未出现富营养化的问题 ,库水与蓄水前溪水水质有所不同。 [结论 ]通过实施传染病预防 ,开展蓄水前环境处理以及水源保护等措施 ,基本上能够解决大坝蓄水后对周围人群健康造成影响与水库出现富营养化的问题 [Objective] The research aimed to discuss the preventive review and environmental treatment of mountainous reservoirs and provide guidance for future work. [Method] The changes of disease and water quality before and after storage in 3 reservoirs were compared. [Result] The reservoir did not affect the health of the surrounding people after the impoundment, but the reservoir did not have the problem of eutrophication. The water quality of the reservoir water was different from that before the impoundment. [Conclusion] The prevention of infectious diseases, the pre-storage environmental treatment and the protection of water sources can basically solve the problem of health impacts on the surrounding population and the eutrophication of reservoirs after water storage in the dam
