摘要
石材的开发不可避免地要破坏矿区原有的生态环境,同时形成大量高陡岩质边坡(白茬山)。高陡岩质边坡由于其坡度陡,高差大,坡面长,坡面温差变化幅度快且大等,其植物生境条件极其恶劣,致使其难以实现长期的复绿效果,所以历来都是矿山生态环境修复工作中的难点。对植被地境重塑技术、坡面复绿技术、植被特征组合及后期管护进行了综述,进而总结了相关技术特点及其优缺点。指出在露天高陡岩质边坡修复工程中,需在调查矿区土壤、植被、地质、构造、水文、气候、气象等条件的基础上,充分考虑岩性、坡度、坡向、坡长、基岩裂隙发育特征、本土植被的特征组合对修复方案选取的影响。对地境重塑技术、植被特征组合和低成本管护技术的研发等方面进行了展望。
The high-speed development of national economy can not be separated from the development of stone,which will inevitably destroy the original ecological environment of the mining area and form a large number of high and steep rock slopes(white stubble mountain).Due to its steep slope,large height difference,long slope surface and large temperature difference,the plant habitat condition of high and steep rock slope is extremely bad,which makes it difficult to realize the long-term greening effect,therefore,it is always a difficult point in the mine ecological environment restoration work.In this paper,the technology of vegetation reconstruction,the technology of slope greening,the combination of vegetation characteristics and the later management and protection were summarized.It is pointed out that in the restoration project of high and steep rock slope in the open air,it is necessary to investigate the soil,vegetation,geology,structure,hydrology,climatic and meteorological conditions in the mining area,the influences of lithology,slope,aspect,slope length,bedrock fissure development and native vegetation on the selection of restoration scheme are fully considered.The prospect of the research and development of the techniques of landscape reconstruction,vegetation feature combination and low-cost management and protection is also discussed.
