The area is located in the southern subtropics with abundant rainfall, high temperature, lush vegetation and over 500 meters of high mountain area. There is basically no accelerated erosion in modern times. However, due to the convenient traffic, dense population, serious vegetation destruction and bare rock , Weathered, is a serious water and soil loss areas. Soil erosion has become a major obstacle to the development of local production. Two Different Types of Soil Erosion 1. The types of surface and small ditches that are represented by Luoding (a) There are mainly four distributions: (1) Luoding tablets, including prime dragons in Luoding County, Huashi, Shuangdong, Fucheng, Li Shao, Shengjiang and other communes and Yuenan’s Grand Bay, estuary, thousands of officers and other communes; (2) Huaiji films, including Huaiji County Fucheng, happiness, gate , Wenlang, cold pit, horse
