摘要
矿区废渣地植被破坏转换成荒漠化的过程符合生态阈值特征。植被稳态和荒漠稳态之间的转换存在稳态阈值、稳态恢复力和稳态极限,形成了影响稳态恢复因子和稳态转换的动力。通过对植被稳态和荒漠稳态的生境条件的分析,提出了影响这两种稳态恢复力的因素,同时对稳态转换的驱动力进行了分析;并阐述了植被稳态向荒漠稳态的变化过程。
The conversion process of mining waste land in which vegetation was destroyed to barren desert accorded with the characteristics of the ecological threshold.There are steady state threshold,steady state resilience and steady state limit when shifting between vegetation and barren desert steady state.The factors influenced the restoring forces of vegetation and barren desert steady state were proposed,the driving forces of steady states transformation were discussed,and the change process of vegetation steady state to barren desert steady state was expounded.
