雨水边坡植被绿化节水技术及效果研究

Study on the Water Saving Technology and Its Effect for the Vegetation Greening of Rain Slope

为加快岩质边坡绿化速度、节约水资源,结合雨水花园原理,首次提出"雨水边坡"概念,并制定3种雨水边坡技术方案,在校园内搭建实验池,进行了以土壤含水率为代表的节水实验。实验结果表明,3种雨水边坡技术方案均具有节水性,节水能力受干旱时间长短的影响而不同,但30d均可维持土壤含水率10%左右,为北方干旱、半干旱地区矿山岩质边坡植被绿化技术提供了新方法、新思路。

In order to promote the greening of rock slope and save water resources, the concept of ＂rain slope＂ was put forward for the first time through combining with the principle of rain garden. And three technical schemes on rain slope were provided. Three experiment pools were set up in the campus, and the water saving experiment represented by soil moisture content was carried out. The experimental results showed that three schemes all had the characteristic of water saving. And the water saving ability was different due to the influence of different drought time, but the soil moisture content in 30 days could keep about 10%. As a result, the study provided a new method and a creative idea for the vegetation greening technology of mine rock slope in the arid and semi-arid areas in the north of China.
