水库、塘坝工程在克东县农业抗旱灌溉中一直都发挥着重要作用,水库和塘坝产生库区淤积是所控制流域上多种自然因素和人为因素综合作用引起水土流失的结果。近几年,克东县加大了库区水土保持综合整治力度,取得了一些成效。一、库区淤积成因的分析(一)入库沟道泥沙的影响入库沟岸边坡植被覆盖率低,保土固沙能力弱,表土层流失进入沟道。沟底比降较大,下切严重,沟道内没 Reservoirs and dam projects have always played an important role in drought control irrigation in Kedong County. Sedimentation in reservoirs caused by reservoirs and pond dams is the result of soil and water loss caused by a combination of natural and man-made factors in the controlled watershed. In recent years, Kedong County has stepped up efforts to comprehensively rectify soil and water conservation in the reservoir area and made some achievements. First, the reservoir siltation causes (A) the impact of sediment into the channel Trench into the ditch slope vegetation cover is low, soil-fixing ability is weak, surface soil loss into the channel. Ditch lower than the larger cut, severely undercut, the channel did not
