宁阳县蒋集镇彩山小流域水土保持技术研究

Study on Water and Soil Conservation in Caishan Stream in Jiangji Town of Ningyang County

该文分析研究了彩山小流域的区域坡度和土壤特性，并根据区内土壤性质划分出4个小区域，即：自然坡度在20°～25°内为V1区，15°～20°内为V2区，10°～15°内为V3区，5°～10°内为V4区，分别反映了不同的土壤等级及土壤抗冲能力。同时，也研究出了一个系统化、理论化的科学依据i=V（10/3）/5B，并对所有砂石山区水土保持治理工作具有借鉴性和实用性。

Regional stope and soil characteristics in Caishan region are introduced in this paper. According to soil property, this area is classified into four little regions, that is. region with the natural stope in 20°-250° is classified into V1 ,in 15°-200° is classified into V2 ,in 10°-150° is classified into V3 and in 5°-100° is classified into V4. It reflectes different soil degree and soil shock-resisting ablity. A systematic and scientific basis of i=V（10/3）/5B is set up to provide basis for water and soil conservation.
