【摘要】 广州市的重要饮用水源流溪河水质良好,但近年有富营养化的趋势。调查表明,影响水质的污染源主要有库区周围农田、果园施用化肥、农药等随地表径流形成的面源污染,畜禽养殖的污水排放,库区乡镇及农村生活污水和生活垃圾形成的点污染源,库区周围餐饮业和旅游业形成的污染等。水库集水区的水质保护的关键是走生态优先与农业清洁生产的生态农业之路,控制面源污染,为此本文从农业生态学与生态经济管理的角度,提出减少面源污染的几种生态农业模式与生态农业技术体系,并从政府管理角度提出了具体的策略措施。更多还原

【Abstract】 Liuxihe River is the main source of drinking water of Guangzhou city. Though the water quality of Liuxihe Reservoir has not exceeded the limitation set by the national standard of surface water quality (GB 3838—2002), but it shows the tendency of eutrophication. The investigation showed that the non-point source (NPS) pollutant from agriculture was a very important reason. The NPS pollutants from agriculture, including chemical fertilizers, waste released from livestock and poultry, polluted water from aqua farms, domestic sewage, domestic wastes and soil erosion were analysis. Based on the research results obtained so far, discussion is made to work out the strategies and methodology for integrated controlling of agricultural non-point source pollution. Some ecological agricultural system model and its technological systems that are adaptive to the watershed of Liuxihe Reservoir are porposed.更多还原
