发展坡地农用林业治理农业面源污染

当前由于水土流失导致的农业面源污染问题越来越严重。针对水源地土壤过度营养、坡地绿化率低、森林质量不高等问题,围绕控制农业面源污染,改善农村环境质量这个中心,提出从改善农业生产条件、加强坡岸植被缓冲带建设等方面入手,注重因地制宜,大力发展坡地林业,培育森林资源,最终控制农业面源污染。可见,发展坡地林业对于减缓农业面源污染具有非常重要的意义。

Developing Agroforestry in Slope Land to Control Non-point Source Pollution in Agriculture

At present,non—point source pollution in agriculture is becoming more and more serious in the country,and the loss of soil and water had caused the such problems in the course.In view of the environmental problems such as soil eutrophication and low forest coverage in the headwaters region,lower quality of stands,some measures are presented in the paper such as improving agricultural conditions,enhancing plant buffer zone construction,developing agro-forestry to increasing forest resources and largely developing forests in the slope land and etc.,finally to control non-point source pollution in this area.Thereby the benefits of pushing up agro-forestry in sloping field to refrain soil eutrophication and non-point source pollution from worsening are significant.
