宕口资源生态恢复与开发利用模式研究——以苏州高新区为例

The Ecological Restoration and Exploitation of the Pit Resources——Taking Suzhou New District as an Example

以苏州市高新区的宕口资源为例，对其植被恢复状况进行了调查，结果表明，自2002年底全面停止开山采石以后，关闭的矿山废弃地环境恢复整治示范工程已初见成效，各个宕151的绿色植被在逐渐恢复。道渣型宕口立地条件好，植被生长良好，植被覆盖率较高；花岗岩型宕口立地条件差，植被恢复难度大，宕171植被覆盖率相对较低。借鉴我国宕口修复的成功范例，提出了建设生态公同、生态住宅、循环经济、生态墓葬及科学复绿等宕口资源开发利用模式。

Based on Suzhou, Jiangsu Province in High-Tech Zones unconstrained Resources example, the pits in the ecological recovery of the investigation, The results showed that since the end of 2002 the complete cessation of the quarry, Close to the disused mining environmental restoration training demonstration projects have yielded initial resuits, and the various pits in the green vegetation gradually restored. Road type of slag pits in good soil conditions, soil moisture, nutrient appropriate, good vegetation, vegetation coverage rate higher. The granite-type soil pits in poor conditions, and the restoration of vegetation difficult, the coverage of plants is lower in pits. Drawing on the research results, raised construction of ecological park, recycling economy, et al. pit resources developmental and uti- lization models.
