| 摘 要： | 立体绿化是一种投资少、见效快,特别对立交桥能起到很好的绿化效果的绿化形式。但是立交桥区绿化养护困难,尤其是水分补充。通过对比实验证明使用覆盖技术可以明显的增强基质的保水能力,从而起到节水作用,同时减少人工补水工作量。从节水效率讲覆膜的高于覆盖树皮,覆盖树皮高于覆盖石子。

| Abstract: | As a form of virescence,stereo virescence needs less investment but takes effect quicker,and its effect is marvelous especially in cloverleaf junction projects.But it's difficult to maintain cloverleaf junctions,especially in adding soil water content.It is proved by contrast experiments that using mantles can greatly improve the matrix's water maintaining ability,in this way water content can be added,and the workload is reduced.In terms of water economizing effect,mantles of velamen have better effect than cortex,then stones come the third. |
