摘要

土壤侵蚀等级的确定是水土保持工作中的重要问题。参照土壤侵蚀强度分级拟定标准进行等级划分时

由于其标准是界限明显的量化标准

指标的选择

权重及侵蚀程度、范围等都具有模糊性。在物元分析方法中引入模糊数学中的隶属度概念

建立模糊物元模型来确定土壤侵蚀强度等级更具合理性。通过实例分析

并与模糊综合评判方法和实际调查结果进行对比

表明此模型是合理、可行的。

Abstract

Classification of soil erosion is an important topic in soil and water conservation.Since the classification standards

such as obvious demarcation lines

choice of factors

determination of weights

and the degree and range of soil erosion

are fuzzy

classification of soil erosion evaluation model is made by matter element analysis based on the subject function of fuzzy.Moreover

the specific application of the model is introduced in contrasting with fuzzy comprehensive evaluation model and actual examples.Results show that the model is rational and feasible.
