准格尔旗皇甫川的五不进沟小流域,1980年开始进行试点治理,到1983年底流域内发生了显著变化,一是流域的自然景观变好了,二是流域的经济效益提高了。下面将流域治理和成效调查分析如下。 一、流域基本概况 五不进沟小流域是皇甫川流域内长川右岸的一条小支沟。流域面积3.2平方公里,海拔高度1170米～1331米,相对高差161米,流域纵坡为4.3%。流域地形地貌属黄土丘陵沟壑区,表层为第四纪风积黄土,薄厚不均,一般2～20米,下层为白垩纪砂岩,中
Zhunge’er Banner Huangfuchuan five non-small into the valley, piloted in 1980 began to pilot by the end of 1983, significant changes have taken place, first, the basin’s natural landscape become better, and second, the economic benefits of the basin increased. The following basin management and effectiveness survey is as follows. First, the basic profile of the basin Five non-into the small watershed is the Huangfuchuan watershed on the right bank of a small tributary. The basin area of 3.2 square kilometers, altitude 1170 meters ~ 1331 meters, the relative elevation of 161 meters, basin longitudinal slope of 4.3%. Watershed topography is a loess hilly and ravine, the surface of the Quaternary windy loess, uneven thickness, usually 2 to 20 meters, the lower Cretaceous sandstone, medium
