废弃采石场岩质边坡绿化技术及废弃地开发利用探讨

Application of Bio-engineering on abandoned rock-quarry slopes and ultilization of abadoned land

随着我国经济实力的增强和土地资源的利用,人们对废弃采石场岩质边坡绿化及其废弃土地开发整理越来越重视。在本土飘台法、鱼鳞穴法、燕巢法、阶梯台阶法及钢筋混凝土框格悬梁等绿化技术应用的基础上,作者引进了客土喷播法、液压喷播法、三维网喷混植生法、喷混植生法等国外边坡防护绿化新方法,并重视废弃地的开发利用,不仅挖掘出废弃地的土地资源和旅游资源等潜力,而且产生巨大的社会、经济和生态环境效益。文章从废弃采石场环境治理需要解决的岩质边坡绿化及废弃地利用两方面,探讨了绿化技术的适宜性及废弃地开发利用的最佳方式。

Because of the shortage of land resources, the demand for planting and re-utilization of abandoned quarry sites is very urgent in China. Based on the current bio-engineering techniques, such as float stage filled with local earth method, scale pit method, swallow nest method, ladder method and hanging cement lattice method, the author introduces the methods of gush seeding in exotic earth, gush seeding using hydraulic pressure, gush mixture in 3-d netting, gush mixture from abroad. The abandoned land can be re-utilized and has great value. In this paper, the author discusses how to select the fight planting method and the land re-utilization method.
