高陡岩质边坡植被修复的立地条件研究——以洛阳市宜阳锦屏山为例

Study on Site Conditions for Vegetation Restoration on the High and Steep Rock Slope——A Case Study in Jinping Mountain of Yiyang City

以洛阳市宜阳锦屏山采石场高陡岩质边坡为例,通过对锦屏山高陡岩质边坡岩壁裂隙发育情况、裂隙的温湿度和裂隙内土壤肥力等植物立地条件的调查与分析,认为岩壁发育的裂隙可为植物提供充足的水分和根系发育空间,裂隙内留存的土壤肥力高可为植物生长提供养分,裂隙内的温湿度条件适宜植物的正常生长,因此若能对这些岩壁条件合理利用,并加以适当的人工改造,可实现高陡岩质边坡的快速覆绿,对废弃采石场陡壁小生境生态恢复重建具有重要的意义。

With the development of society and economy, people pay more and more attention to the vegetation restora- tion of rock slopes in abandoned quarries. This paper surveys the site conditions for vegetation restoration on the high and steep rock slopes of quarries in Jinping Mountain,and finds out that fractures can supply enough water and root development space for plants,the soil in fractures can provide nutrients for plant growth, and the temperature and hu- midity conditions in fractures are suitable for the normal growth of plants. The paper proves that, after some artificial modification, these conditions will be suitable for vegetation restoration and the rapid revegetation of the rock slope can be realized,which is significant to the ecological restoration on the rock slopes of abandoned quarries.
