浙江省仙居永安溪支流河道护坡植物的水分生态效应研究

The Water Ecological Effects of Slope Protecting Plants on Yong＇an Stream of Xianju, Zhejiang Province

于2011年7月份测定了浙江省山区河道坡面上生长的草本植物的生物量及其叶片的蒸腾作用速率，据此计算出植物的降温和增湿效能。结果表明：五节芒在山区河道中的护坡效果最好，其它植物依次为水芹、辣蓼、羊蹄。

Four species of slope protecting plants in mountain stream were studied in July in 2011 for detecting their hiomass and transpiration rate, calculating their temperature lowering and humidity increasing effects. The results showed that the Miscanthus floridulus （Lab.） Warb. ex Schum. et Laut had good effects of temperature lowering and humidity increasing, which showed good slope protecting effect in mountain stream of Zhejiang province. Next to Oenanthe javanica （B1.） DC, Polygonum tinctorium Ait and Rumex iaponicus Houtt.
