西北高原生态脆弱区因采矿造成裸露基岩边坡的恢复治理浅谈——以甘南地区为例

Restoration and Treatment of Bare Bedrock Slope Caused by Mining in Ecologically Vulnerable Area of Northwest Plateau--Taking Gannan Area as an Example

甘南地区地处青藏高原东北边缘,矿产资源丰富,矿业开发活动活跃。本文针对目前西北高原区(甘南地区)因采矿造成裸露基岩边坡治理进行研究,根据甘南地区的地质环境实际和甘南地区在矿山恢复治理工作遇到的技术难点,提出治理措施和建议。根据边坡高陡、质地等微环境的不同,本着因地制宜、分区设计、科学经济、景观相似、快速见效的原则,采用现代喷播和传统覆土种植技术相结合,以最小的经济代价,最大限度和最快速度地恢复受损的山体基岩边坡,取得良好的景观、生态和水土保持效果。

Gannan region is located in the northeastern edge of the Qinghai-Tibet Plateau,rich in mineral resources and active mining activities.In this paper,the treatment of bare bedrock slope caused by mining in the Northwest Plateau(Gannan region)is studied.According to the actual geological environment in Gannan region and the technical difficulties encountered in mine restoration and treatment in Gannan region,the control measures and suggestions are put forward.According to the difference of micro-environment such as high and steep slope and texture,in line with the principles of local conditions,zoning design,science and economy,similar landscape and quick effect,modern spraying and traditional covering soil planting technology are combined to restore damaged mountain bedrock slope with minimum economic cost and maximum and fastest speed,thus achieving good landscape,ecological and soil and water conservation effects.
