湾山废弃石矿生态复绿试验示范初报

Preliminary study on ecological revegetation of abandoned quarry in Wanshan town

对废弃石矿进行生态和景观修复等综合治理一直是一道难题。2003年浙江省湖州市湾山废弃石矿的治理和生态复绿工程,采用工程绿化的方法:前期通过削坡和在坡面钉网等措施来增加客土层厚度,营造植物生长基质层,然后喷播植物种子等材料到坡面,后期进行一定时间的养护来促进新建植被的生长。经过对该项目2年多时间的全程跟踪调查,结果表明:采用的这套生态治理技术不但能较好地控制水土流失,而且能减轻地质灾害的发生,并在较短时间内实现矿区植被的恢复,改善原有被破坏的环境,具有推广价值。

Exploiting the quarries without any planning has broken the landscape of the city surroundings and resulted in serious soil erosion, and caused geological disaster as well. How to deal with these quarries comprehensively is still a serious problem for the local govenment. In 2003, a program of ecological revegetation on an abandoned quarry in Wanshan town, Huzhou city, Zhejiang Province has been put into practice, which adopted both engineering and vegetation methods. In this program, paring the steep slope and nailing net on the slope were done firstly to increase the thickness of artificial soil, and then the plant growth based layer was constructed and the plant seeds were sprayed by hydroseeder, and at last the protecting and managing were done to help the plant recovering. The progress of this program was investigated for the past two years , which showed that this ecological technology could prevent soil erosion and eliminate geological disasters better than simple engineering methods, and revegetate the mining area in short time and improve the original landscape. In some cases, the ecological technology is a good example for other quarries.
