张家口地区永定河流域面积14792km~2,1983年列入全国八片水土保持重点治理区时尚有水土流失面积9272km~2。经过9年的连续治理,该区共完成综合治理面积2977km~2。已验收的40条小流域,林草植被率由原来的16.2%增加到46%,有的削洪效率达到63.5%,大大减轻了洪水灾害;人均占有粮食由治理前的317kg增加到540kg,人均经济收入由179元增加到418元。加强领导,建立健全水土保持机构,以经济效益调动群众治理积极性,坚持以小流域为单元、以村为单位进行治理,实施适应干旱特点的治理措施,是搞好重点治理的关键。1993~1997年,第二期工程仍以4%的年治理速度继续投入治理,计划完成治理面积2000km~2,使区内水土流失治理程度达到50%以上。
Zhangjiakou area Yongding River basin area of 14792km ~ 2, 1983 included in the national eight key areas of soil and water conservation and management of soil erosion area of 9272km ~ 2. After nine years of continuous management, the district has completed a comprehensive management area of 2977km ~ 2. In the 40 small watersheds that have been accepted, the vegetation coverage rate of forest and grassland has increased from 16.2% to 46% and some of the flood-cutting efficiency has reached 63.5%, greatly reducing flood disasters; the per capita food grain has increased from 317kg before treatment to 540kg per capita Economic income increased from 179 yuan to 418 yuan. To strengthen leadership, establish and improve water and soil conservation agencies, and mobilize the enthusiasm of the masses for economic benefits, adhere to the principle of using small watersheds as a unit and village as a unit and implementing measures to control drought are the keys to doing a good job of key governance. From 1993 to 1997, the second phase of the project will continue to be put into operation at an annual treatment rate of 4%. It plans to complete the control area of 2000km ~ 2 so that the degree of soil and water loss control in the area will reach over 50%.
