辽宁省柳河上游水土流失面积1034.78km~2,部分地区年土壤侵蚀模数高达10000t/km~2以上。严重的水土流失,导致上游群众生活贫困,下游河道泥沙淤积,使柳河变成地上悬河,洪水灾害发生频繁。柳河上游自1983年被列入全国水土流失重点治理区后,10年共完成水土保持综合治理措施保存面积579.87km~2,其中水平梯田4210.5hm~2,坡式梯田12535.3hm~2,保土耕作措施1886.1hm~2,造林21678.2hm~2,种草5827.9hm~2,牧场改良9427.9hm~2,种植果树1116.4hm~2,封山育林1175hm~2,闸沟造地2.67hm~2,
The area of soil erosion in the upper reaches of Liu River in Liaoning Province is 1034.78km ~ 2, and the annual soil erosion modulus in some areas is as high as 10000t / km ~ 2. Serious soil and water loss, leading to poor living in the upper reaches of the downstream river sediment deposition, so Liu River into a hanging river, frequent flood disasters. Since the upper reaches of Liuhe River was included in the key areas for soil and water loss management in 1983, a total area of 579.87km ~ 2 has been established for the comprehensive management of soil and water conservation in 10 years, of which 4210.5hm ~ 2 for terraced fields, 12535.3hm ~ 2 for terraced terraces, The cultivation measures were 1886.1 hm ~ 2, 21678.2 hm ~ 2 for afforestation, 5827.9 hm ~ 2 for grasses, 9427.9 hm ~ 2 for pasture, 1116.4 hm ~ 2 for fruit trees, 1175 hm ~
