招远市黄金尾矿库生态工程技术研究与实践

招远市现有黄金尾矿库不仅占用大量土地资源,对周围的空气、土壤、水体造成污染,破坏周围的生态环境,而且存在安全隐患,严重制约了当地经济社会的可持续发展.针对不同类型黄金尾矿库的特点,建立了漫溢型生态景观园、高台型生态休闲园、坝坡型风景防护林地、沟夼型生产园地等4种黄金尾矿库生态工程模式.通过生态工程示范区建设,将尾矿库改造成城镇景观绿地、生产园地,解决了黄金尾矿库的生态环境问题.

Technological Study and Practice on Ecological Engineering of Gold Tailing Ponds in Zhaoyuan City

Gold tailing ponds in Zhaoyuan City not only took up a lot of land resources, but also polluted air, soil and water. They also destroyed surrounding ecological environment and existed security hidden trouble. The local sustainable development was seriously restricted. According to the characteristics of different gold tailing ponds, four ecological engineering patterns were founded, such as the spillover ecological landscape park, the high-- profile ecological leisure park, the dam--slope scenery protection forest land and the ditch production field, in which the ditch production field pattern can be divided into three kinds of patterns, such as garden nurseries, timber and economic forest. The eco--environmental problems were solved though rebuilding gold tailing ponds into urban landscape green lands and garden plots.
