黑龙江省拜泉县治理侵蚀沟采取草垡式跌水,取得较好地效果。 草垡跌水优点:一是由于工程都是用活草垡镶护的,草垡成活率高,可形成草封沟,草皮的根可固土防冲,所以能充分发挥工程措施与生物措施相结合的作用,达到稳定沟头、固定沟底,防止侵蚀沟的发展。如新生乡兴安村1981年春在村的东北一条侵蚀沟里,修建了 Baiquan County, Heilongjiang Province, to control the erosion ditch to take draconic grass, achieved good results. Grass 垡 fall advantage: First, as the project is live grass 垡 inlaid, 草 survival rate is high, the formation of grass seal ditch, turf root can soil anti-impact, it can give full play to engineering measures and biological measures A combination of the role to achieve a stable ditch, fixed ditch, to prevent the development of erosion ditch. For example, Xing’an Village, Xinsheng Township, was constructed in an eroded ditch northeast of the village in the spring of 1981
