Application of Fuzzy Variable Evaluation Model in Soil and Water Conservation
LIAO Chongyuan
Abstract：Soil erosion control is one of the most important ecosystem services provided by soil conservation technologies,widely used to alter hydrological and soil processes and improve ecosystem services.However,evaluating the actual state of a sustainable soil and water conservation quality assessment system has become a challenge.The fuzzy variable evaluation model can scientifically and reasonably determine the relative membership degree and function of various indicators related to soil erosion in engineering projects,expressed as interval values.By utilizing the variable evaluation model and its parameters,it can accurately define the evaluation grades related to soil erosion,thereby enhancing the credibility of the evaluation results for the study area.Additionally,this model was applied to evaluate the soil and water conservation of the flood control project in Shiqian County,Guizhou Province,and compared with other evaluation methods.The results showed that the model's calculations were reliable and could be applied to soil and water conservation grade evaluations in various practical engineering fields.
