Abstract: Different using Fllodes of precipitation’s surface flow，the caused soil erosion，dynamic change of soil moisture and soil nutrient’s and their space-time distribution have announced the technological principle to keep water and soil resources standing and high-efficient in the hillside fields，giving a corresponding value of water and soil of red soil developing from the fourth century laterite texture，The result also indicates that so long as the management and development can be combined organically，the hillside fields of mound can be cultivated by a large scale and will not cause soil erosion．
