摘　　要：对九曲湾水库污染源进行调查和水质现状监测,得出其主要污染物为氮磷,其次是农药和有机氯化物。果业种植中不合理的坡地开发,措施不到位导致土壤侵蚀—营养盐的流失;同时果业种植科学管理不到位,滥用化肥、农药造成面源污染。点污染源是农村生活污水和生活废弃物以及畜禽养殖所产生的部分污染物。同时水库为峡谷形的河道型水库,不利于污染物的迁移转化。Based on the investigation of pollution sources and monitoring of water quality status quo,we find that nitrogen and phosphorus are the main pollutants,followed by pesticides and organic chlorides. Unreasonable use of slope in the fruit planting and taking unscientific measures lead to soil erosion-nutrient loss. Meanwhile,abuse of chemical fertilizers and pesticides because of improper management during fruit planting further leads to non-point source pollution. The pollution sources include the rural sewage and waste,and pollutants produced by livestock and poultry breeding. The reservoir is a canyon-shaped river reservoir,which is not conducive to the migration and transformation of pollutants.
