摘　　要：水土保持模糊专家系统是把模糊技术引入专家系统领域,以处理水土保持专家知识中存在的大量的模糊性和不确定性.该文对水土保持模糊专家系统的原理进行了探讨,从其结构组成、模糊知识的表示和模糊推理技术3个方面进行了论述.最后指出这些也是水土保持模糊专家系统与普通专家系统的重要区别,它可以使专家系统能更客观地描述现实世界的模糊性和不确定性,对水土保持学科领域的问题进行专家级的解答.Soil and Water Conservation Fuzzy Expert System is that the fuzzy technology is introduced into expert system to deal with fuzzy and indeterminate knowledge of expert in soil and water conservation. This article makes an inquiry into the principle of Soil and Water Conservation Fuzzy Expert System from the three aspects:the structural composition, the expression of the fuzzy knowledge and the fuzzy inference technique. The new system is different in these aspects from the Fuzzy Expert System and the ordinary Expert System. At last it is indicated that Soil and Water Fuzzy Expert System can describe the fuzzy and indeterminate knowledge in the realistic life more objectively, and can answer the problem of soil and water conservation at the expert level.
