岗沟流域位于甘肃省临夏县东北部,属黄土高原丘陵沟壑区第四副区,总面积46.52km~2,其中:山区面积13.67km~2,原区面积32.85km~2。1984年,根据国家计委下达的“编制西北黄土高原水土保持专项治理规划”任务,水保部门提出了该流域1986～2000年综合治理规划。1987年该流域又被列为省重点治理流域。近几年来,在流域内开展了以改造基本农田、种草种树和封坡育草为中心的综合治理,共完成初步治理水土流失面秒40.16km~2。目前,流域内的农业结构已得到较为合理的调整,群众收入逐年增加,显示出明显的水土保持效益和社会效益。
Gangou Drainage Basin is located in the northeastern part of Linxia County, Gansu Province. It belongs to the fourth sub-district in the hilly and gully area of the Loess Plateau with a total area of 46.52km ~ 2, of which: the mountainous area is 13.67km ~ 2 and the original area is 32.85km ~ 2. In 1984, The State Planning Commission issued the “preparation of Northwest Loess Plateau Soil and Water Conservation Special Governance Plan” task, the water conservation department put forward the basin from 1986 to 2000 comprehensive management plan. In 1987 the basin has been listed as the provincial key management basin. In recent years, comprehensive management has been carried out in the catchment areas with the focus on transforming basic farmland, planting trees and grazing grass, and completing 40.06km 2 of surface water control. At present, the agricultural structure in the basin has been more reasonably adjusted, and the mass income has been increasing year by year, showing obvious benefits of soil and water conservation and social benefits.
