城市垃圾填埋场植被恢复研究进展

Review on Municipal Refuse Landfills Virescence

城市垃圾填埋场占用了大量的城市用地,并使得许多可利用资源如适量的碳、氢、钾、钙、镁、磷和微量的铁、锰、铜等元素被浪费,而且污染并破坏了周围的生态环境,有时候还引起爆炸。如何对封场后的城市垃圾填埋场进行合理高效的开发利用,成为国内外学者研究的热点。通过回顾国内外城市垃圾填埋场土地利用方式、绿化潜力、树种选择研究进展,对垃圾填埋场存在的诸如填埋气体、渗漏问题、植物的养护、土壤贫瘠等对垃圾填埋场绿化产生限制的因子进行探讨,提出找到垃圾填埋场绿化的综合配套技术如绿化美化规划方法、适宜的草种和树种、配套的绿化方法等将成为今后研究的重点与热点。

Municipal refuse landfills not only impropriately occupy abundant city land ,but also make much useful resource for instance carbon , hydrogen , kalium , calcium , magnesium , phosphor , iron , manganese , copper wasted, even more have environment damaged ,sometimes bring exploders. Many researchers of many countries are studyingits efficient use. By looking back the virescence potential , the methods of land use , the choice of compatible plant on municipal refuse landfills in China and other nations , and studying on the harm in municipal refuse landfills , the limits to virescence that are LFG , the leakage , the faultiness maintainability, the lean soil and so on, at last,the focus is put forward in the series technology, the programming ways , the feasible plants for the future.
