摘　　要：随着中国经济的迅速发展,城市河流的改善成为受关注的热点,新时期城市道治理工程,除了要满足防洪排涝要求,保护河道的自然风貌,美化环境,也要符合生态的科学性原则,通过室内水槽模型试验,对河道修建挡水建筑物后在3种不同坡度下水流特性变化进行实验研究。通过分析作者认为坡度对坝前雍水及流速的影响比流量要大,希望能为兼顾生态的城市河道治理方式提供依据。With the rapid development of Chinese economy ,urban river improvement has been concerned hot .In the new period,urban river treatment project not only should satisfy the flood and draining waterlogging requirements, protect the fiver natural style, beautify the environment, but also vaea to accord with ecological principle of scientific.The article through indoor cistern model test to investigate the building block water uildings flow sharacteristics in three different kinds of the bottom slope .Finally through the analysis that Slope of dam before harmony water and lnfluence than flow velocity,, The hope for both ecological city river governance mode provides the basis
