1988年秋季,对黑龙江省西部地区受到严重冲刷的一条典型农田侵蚀沟进行了以生物措施为主的综合治理。采取的主要措施是:在沟头上方营造截流林带,修筑沟头坝;在沟坡两侧营造防蚀林带,削坡插柳,修筑封沟埂;在沟内密插防冲林带,设置土谷坊和柳编谷坊。经过5年的治理,收到了良好的效果。治理后的1993年与治理前的1988年相比:该侵蚀沟每年向源侵蚀速度由2.50m 减少到0.05m;沟帮崩塌速度由每年0.60m 减少到0.03m;每年侵蚀农田数量由1000m~2减少到19.94m~2;平均沟深由2.18m 变为1.66m;泥沙进出量由侵蚀2500m~3变化到淤积358.3m~3,5年内共淤积泥沙720 55m~3
In the autumn of 1988, a comprehensive farmland erosion ditch undergoing serious erosion in western Heilongjiang Province was comprehensively managed with biological measures. The main measures to be taken are as follows: to create a truncated forest belt at the top of the ditch head and to build a gully dam; to create an anti-corrosion forest belt on both sides of the ditch slope; And Willow Valley. After 5 years of governance, it received good results. Compared with that before 1988, the erosion rate of erosion gully reduced from 2.50m to 0.05m per year; the collapse speed of gully was reduced from 0.60m to 0.03m per year; the number of erosion fields from 1000m ~ 2 to 19.94m ~ 2; the average depth of the furrows changed from 2.18m to 1.66m; the sediment inflow and outflow changed from 2500m ~ 3 to 358.3m ~ 3, and a total sediment deposition of 720 ~ 55m ~ 3
