【摘要】 鉴于磷为水体富营养化的主要因素之一,文章把密云水库水体分为表层(0～10m)、中层(10～20m)、底层(>20m)三层,用有限元法对密云水库水体总磷进行了分层的数值模拟,比较了三层水体总磷的分布状况,并分析了产生分布差异的原因。更多还原

【Abstract】 Owing to that TP is one of the most important influence factors of water eutrophication, the Miyun reservoir’s TP distribution is divided into three layers-the surface layer (0～10m), medium layer (10～20m) and bottom layer (>20m). Making the imitative test individually to the Miyun reservoir’s TP distribution of three layers by using the finite-element method. The TP distribution is compared with three layers, and the reason of the distributive difference is analyzed in this paper.更多还原
