| 摘 要： | 根据降雨及其引发土壤侵蚀是一个连续变化过程的特点,基于次降雨雨量(P)和最大30 min雨强(I30)建立了侵蚀性降雨识别的模糊隶属度模型.模型分为3个部分:①推求次降雨各物理参数的模糊隶属度；②将各物理参数的模糊隶属度有机结合起来,获得次降雨的模糊隶属度；③依据次降雨模糊隶属度对自然降雨事件进行判别,筛选出其中的侵蚀...

| Abstract: | Soil erosion caused by rains is a continuous process of changes.Such a soil erosion character is used in the development of a fuzzy membership model for identifying erosive rainfall events.The precipitation amount(P) and the maximum 30 min rainfall intensity(I30) of a rainfall event are used as two physical parameters in the model.The model involves three parts.The first part calculates the membership values of P and I30,and constructs the fuzzy membership functions.Secondly,the membership values of P and I... |
