根据本区的地形、水文,地质及水文地质特点,按河网化的需要,概可划分为以下几区: 工 区 本区范围位于调查区之南部,标高一般在200—800米之间。地形崎岖,割切强烈,冲沟甚为发育,割切深度一般为10一30M,冲沟长度为500—1000米,长者可达3000—5000M。坡角为20—70°。这些沟谷相互啣接,构成间歇河流。因岩性分布不均,风化强度不一,故在河流间常形成一些袋状地形,如管帅,后泥牛等皆是。这些冲沟与河流构成北部各大河
According to the topography, hydrology, geology and hydrogeology in this area, according to the needs of river network, it can be divided into the following areas: The work area The area is located in the southern part of the survey area. The elevation is generally between 200-800 meters. Craggy terrain, cutting strong, very developed gully, cutting depth is generally 10 a 30M, gutter length of 500-1000 meters, the elderly up to 3000-5000M. Slope angle of 20-70 °. These valleys connect with each other to form an intermittent river. Due to the uneven distribution of lithology, weathered strength varies, so often form some bag-shaped terrain between the rivers, such as tube handsome, mud and so after all are. These gulches and rivers form the northern major rivers
