摘　　要：通过现场勘查、跟踪,分析了荆江河段河漫滩植物群落及植物种类分布,结合实际调查情况选取试验模型植物,开展不同植被对水流结构的影响水槽试验研究。结果表明,植被的存在对岸坡附近水流流速影响明显,增加了水流的阻力,对减轻水流冲刷有较好的防护作用,不同植被高度、不同种植密度对植被根部冲刷具有不同的影响。最后选取周天河段张家榨护岸工程段进行了不同植被生态护坡现场试验,生态效果明显。The plant community and plant species distribution of the Jingjiang reach river floodplain were analyzed through the exploration,tracking,etc.The experimental model plants were selected in combined with the actual investigation,then we carried out the experimental study on the influence of different vegetation on the flow structure.The results showed that the presence of vegetation had a significant influence on the flow velocity near the bank slope,which increased the resistance of the water flow,and had better protection effect to reduce the erosion of the water.The different vegetation height and different planting density had different effects on the root erosion of vegetation.At last,field test of ecological slope protection of different vegetation was carried out in the bank protection engineering section of Zhangjiazha revetment in Zhoutianhe section with obvious ecological effect.
