裸露岩质边坡覆绿的生态地质学指标分析

Analysis on Ecological Geological Index of Bare Rocky Slope Greening

裸露岩质边坡覆绿成败的关键在于植物和岩体的有机结合,植被地境再造技术效果突出.通过以河南省宜阳县锦屏山高陡岩质边坡覆绿工程为研究对象,从生态地质学角度研究地境再造技术指标,为了解决岩质边坡的覆绿这一问题,必须要满足以下条件:岩体体裂隙率达到3%以上、岩壁覆绿植物种植孔深度在40~60 cm之间、种植孔施工角度与裂隙的发育产状相关且以切穿更多的裂隙为原则.

The key to success or failure of bare rocky slope is the organic combination of plants and rock mass, and the remarkable effect of vegetation below-ground habitat recreation technology.The Technical Index of geotecbnical reconstruction was studied from the perspective of ecological geology in the high steep rock slope greening project of Jinpingshan in Yiyang County, Henan Province. In order to solve the problem of greening the slope of rock slope, the following conditions must be met ： volume fissure rate more than 3%, the depth of planting holes between 40 - 60 cm, and the angle of planting hole being related to fracture occurrence as well as taking cutting through more fissures as the principle.6figs., 6refs.
