绵阳市农业面源污染现状及防治对策

介绍了绵阳市农业面源污染现状,包括农用化学品投入量大,利用率低;畜禽养殖量大、粪污有效处理率低;农田废弃物产生量大,资源化利用还有差距。从综合配套治理技术尚不成熟,防治管理制度缺乏,农业生产与资源环境保护矛盾突出,农业面源污染治理未形成良性循环几方面,分析了农业面源污染成因。最后提出了农业面源污染治理对策,包括加强法规建设,强化综合防治措施;实施农药减控工程,治理农药残留污染;实施化肥减量工程,加快土壤改良修复;推进秸秆综合利用工程,实现废弃物资源化;实施畜禽养殖提升工程,建立畜牧生态产业体系;实施清洁生产工程,保护农业生态环境;积极推进重点流域面源污染综合治理;强化监测评估和预警体系建设。

Current Situation and Its Control Measures of Agricultural Non-point Source Pollution in Mianyang City

The current situation of agricultural non-point source pollution in Mianyang City was introduced,including massive agricultural chemical inputs,low utilization rate and large amount of livestock and poultry;manure treatment effective rate was low;a great deal of farmland waste,as well as the gap between resource utilization.The causes of agricultural non-point source pollution were analyzed,from the comprehensive treatment technology immaturely,lack of institutional prevention management,agricultural production and environmental protection contradiction,circulation system of agricultural non-point source pollution unestablished.Finally,the countermeasures of agricultural non-point source pollution were put forward,including strengthening the construction of laws and regulations,strengthening the comprehensive prevention and control measures;the implementation of pesticide reduction and control engineering,control of pesticide residues;the implementation of the reduction of chemical fertilizer project,accelerating the improvement of soil remediation project;promoting the comprehensive utilization of straw,waste material resource;the implementation of livestock and poultry breeding project to enhance the establishment of animal husbandry,ecological industry system;the implementation of cleaner production projects to protect agricultural ecological environment;actively promoting the comprehensive management of non-point source pollution in key watersheds;strengthening the monitoring and evaluation system construction.
