垃圾填埋场生态修复研究与实践——以镇江市城东垃圾填埋场为例

Research and Practice of Ecological Restoration of Landfill——with Chengdong Landfill of Zhenjiang Municipality as an Example

在对镇江市城东垃圾填埋场的填埋土、渗滤液和生态环境现状进行调查的基础上,对其进行了生态修复研究与实践。根据城东垃圾填埋场的具体情况,对其定位为进行绿化修复,目标为使其尽量恢复成填埋前的生态环境。从强耐性、较强耐性、中等耐性和敏感树种中选择了7种树种进行了人工种植。结果表明,垃圾填埋场的填埋气是影响树木生长的主要因素,对大多数植物都存在不利影响,垃圾渗滤液对部分树种生长抑制作用较为明显。

Based on the investigation of Zhenjiang Chengdong Landfill＇s soil, leach liquid and the current situation of ecologi- cal environment, some research and praetice of ecological restoration were carried out. According to the specific situation of the Chengdong landfill, it was positioned to be repaired by greening and the target was to make largest effort to restore the ecological environment of the landfill as before. Seven species of trees were selected from the trees with strong tolerance, relatively strong tolerance, middle tolerance and sensitive species and they were planted. The result indicates that the landfill gas was the main factors that influence the growth of the trees and the majority of the plants were effected adversely. The inhibitory effect of leach liquid on part of the trees＇ growth was obvious.
