| 摘 要： | 基于土壤可蚀性因子、地形因子、植被覆盖因子等的模糊性、不精确性,运用模糊理论将这些影响因子定义为三角模糊数。在此基础上,通过将确定性USLE模型参数模糊化,建立了流域土壤侵蚀量计算的模糊USLE模型。实例研究表明,以模糊理论计算流域土壤侵蚀量,理论上是可行的,计算结果是可信的。

| Abstract: | Based on the characteristics of fuzziness and impreciseness of soil, topography, rainfall and vegetation, the parameters were defined as triangular fuzzy numbers. A fuzzy universal soil loss equation (USLE) mode was established for calculation of regional soil erosion load. Results showed that it was feasible and reliable by using fuzzy sets theory to calculate basin soil erosion load. |
