云南省农业面源污染及绿色发展途径

Agricultural Non-point Source Pollution and Green Development Approach in Yunnan Province

通过分析云南省发展现代农业带来的农田废水、畜禽粪便、农田固废的面源污染及其使得农业发展不可持续的问题,提出云南要实现生态文明,必须走有机农业道路,通过建立动物养殖-有机肥生产-沼气池处理污水-有机肥/沼液沼渣回用于有机种植的一体化循环产业模式可协同削减农田废水、畜禽粪便、农田固废的面源污染,并发挥其绿色发展效用。

A series of environmental pollution problems caused by long-term and massive application of pesticides and chemical fertilizers in modern agriculture have attracted more and more attention.This paper analyzed the non-point source pollution from farmland wastewater,livestock manure,farmland solid waste and the unsustainable agricultural development brought by the development of modern agriculture in Yunnan Province.In order to achieve the goal of ecological civilization,Yunnan must follow the path of organic agriculture,through the establishment of the integrated recycling industry mode of animal breeding-organic fertilizer production-biogas pool treatment of sewage-organic fertilizer/biogas slurry biogas residue back to organic planting,which could also synergistically re-duce the non-point source pollution of farmland wastewater,livestock manure,farmland solid waste and demon-strate its green development utility.
