森林小区河流的污染已成为公众极度关心的问题 ,而污染本身与人类活动所引起的超量淤积有关。因此需一种能预估淤积量的计算方法 ,准确地提供丘陵地形条件下河流的淤积量 ,而现有的多数预估方法受对水文过程认识不足的限制难以满足这种要求。美国农业部开发的ＷＥＰＰ软件适用
River pollution in forest communities has become a matter of extreme concern to the public, and the pollution itself is related to the excess sedimentation caused by human activities. Therefore, a method of predicting the amount of sediment is needed to accurately provide the amount of sedimentation of the river under the condition of hilly terrain. However, most of the existing estimation methods are unable to meet this requirement due to the lack of understanding of the hydrological process. WEPP software developed by the U.S. Department of Agriculture applies
