Moreover LID is easy for implementation and cost effective and operation and management can also be done easily.LID has attracted more and more attention from governmental authorities at different levels and the majority of practitioners. Therefore LID has bright prospects for wide applications in China.展开更多
随着城市化进程加快、气候多变,城市雨雪冰冻灾害日趋严重。针对冬季融雪带来的地表积水问题,利用Storm Water Management Model(SWMM)研究了机械、化学、人工3种清雪措施对冬季寒区城市融雪径流规律和低影响开发(LID)效果的影响机理。...随着城市化进程加快、气候多变,城市雨雪冰冻灾害日趋严重。针对冬季融雪带来的地表积水问题,利用Storm Water Management Model(SWMM)研究了机械、化学、人工3种清雪措施对冬季寒区城市融雪径流规律和低影响开发(LID)效果的影响机理。研究结果发现,3种清雪措施对于冬季寒区城市地表径流调控起到了显著作用,地表径流控制率增幅为5.9%~21.8%。3种清雪措施与LID组合使用后,均可将地表径流控制率提高至85%以上,相较于未清雪情景相比,地表径流控制率提高了40.0%~44.2%;与单独采取清雪措施相比,提高了22.4%~34.1%;与单独采取LID措施相比,提高了1.5%~5.7%。因此,清雪措施与LID的结合使用可提高冬季城市地表径流调控效果,不同清雪方式与LID的组合方式,对城市融雪径流的调控效果差异显著。展开更多
