一、刘家沟小流域的代表性 汾河水库上游水土保持规划包括四县5268平方公里,地类多样,工业影响,政区要求多不相同,需要采取的治理对策和生产建设的方向各异,必须按不同类型地区的特点,选有代表性的小流域,进行典型调查和模式规划。然后按照小流域规划成果,结合面上情况研究制定本类型区技术经济指标的概算定额,为编制上游同类型地区大面积规划提供主要依据和科学论证。因此选择有代表性的典型小流域进行同类型地区的小流域
First, the representative of Liujiagou small watershed Fenhe reservoir upstream water and soil conservation planning, including four counties 5268 square kilometers, land diversification, industrial impact, political requirements are not the same, the need to take control measures and production and construction of different directions , We must select the representative small watershed according to the characteristics of different types of regions and carry out typical surveys and model planning. Then according to the results of small watershed planning, combined with the situation on the surface to study and formulate the technical and economic indicators for this type of area, estimate the quota for the preparation of the same type of area upstream planning provides the main basis and scientific evidence. Therefore, we choose a typical small watershed to carry out the same type of small watershed
