农业现代化的发展和农业生产活动越来越频繁,导致农村面源污染进一步加剧.污染源主要有化肥、农药、农具的过度使用,禽畜粪便、生活垃圾的排放及自然灾害等因素.通过数据调查、列举试验结果等方法分析了污染源对环境的影响;在治理农业面源污染方面,提出了几种新的环境生物防治措施.实践证明,环境生物防治技术比传统治理技术效率高、速度快,更有利于农村环境的可持续发展.%The development of agriculture modernization and frequent agricultural production activities result in the rural non-point source pollution further intensified. The pollution sources are chemical fertilizer, pesticide, excessive use of the tools, livestock waste and solid waste emissions, natural disasters and other factors. The influence of pollution sources to environment was analyzed through data survey and citing the results of experiment methods. Several biological control measures in the governance of agricultural non-point source pollution were proposed. Practice shows that biological control of the environment technologies have higher efficiency, speed and more conducive to the sustainable development of rural environment than the traditional technologies.
