摘　　要：护坡植物选择是生态河道建设的一项重要内容。在初夏季节5月份选取10种杭嘉湖区域常见的河道护坡植物,测定其生物量及其叶片的蒸腾作用速率,计算这些护坡植物的降温和增湿效应。结果表明:辣蓼和云南黄馨的总根数较高,10种护坡植物的日蒸腾释水量和日蒸腾吸热量差异明显,香蒲草、爬根草和云南黄馨在河道中具有较好的护坡性能。It is important thing to choose suitable slope protecting plants in construction of ecological river. 10 species slope protec- ting plants in Hangjiahu regions in May was choosed for detecting their biomass and transpiration rate and calculating their temperature lowering and humidity increasing effects. The results showed that the biomass of Jasminum mesnyi and Polygonum pubescens Blume are the greatest among these slope protecting plants. There are great difference of transpiring water volume and absorbing heat quantity a- mong 10 species slope protecting plants. The plants of T. angustifolia L,Cynodondactylon L and Jasminum mesnyi feature high efficien- cy of slope protection.
