| Abstract: | By using the system SD design method, microcomputer soil and water conservation information system was designed and established on tool software of PC-ARC/INFO or Spaceman. By using developed analystic models in the system, factors influencing soil and water loss was analysed and it was known that the factors are slope, rate of land cover, soil content of sand and gravel, soil erosion resistance index and soil depth. Then by using overlay model, AHP model and comprehensive evaluation model, soil and water loss in Nanfeng county was evaluated and regionalized into 5 regions comprehensively regarding as the scientific basis for soil and water conservation. |
