鞍山市周边铁矿废弃地几种复垦模式的比较

Comparison of Several Reclamation Modes for Land Discarded by Iron Mines around Anshan

以鞍山市周边经复垦的铁矿废弃地为研究对象,在样地调查的基础上,对几种复垦模式的复垦效果进行了比对分析,总结出几种可行的铁矿废弃地复垦方式,即:在满足灌溉的条件下直接在尾矿沙上种植杨树,采用覆土植被法种植杨树,采用柳框固土法复垦排岩场边坡。

Based on the investigation of the sample land plots, the effects of several reclamation modes used for the land discarded by the iron mines around Anshan City are compared. Several feasible reclamation modes for the iron mine waste land are summarized, such as direct planting of poplars in the tailing sands on the condition that the irrigation can be satisfied, poplar planting in earth-covered waste land, and dump slope reclamation by earth-fixing with willow frames.
