Abstract

Soil and water losses have become a serious ecological and environmental problems, and how to scientifically carry out soil and water losses risk assessment on soil erosion prevention and treatment of macroeconomic decisionmaking are very important. Based on the concept of cloud matter element, the associated function and cloud model were used to calculate the association value, then an improved matter-element model of extension cloud combination was established, at last, the evaluation model was introduced into soil and water losses risk assessment. Through the project case in a coal mine shows that the improved evaluation model can get a reasonable risk evaluation result. In practical application, the evaluation result of the extension cloud combination model constructed by classical extension correlation function is closer to the visual statistical value.

Keywords

Fextenics, cloud model, cloud matter element, a coal mine, soil and water losses evaluation.
