黑岱沟大型露天煤矿生态系统稳定性研究

The ecosystem stability study of large open-pit coal mine of Hei-Dai-Gou

黑岱沟露天煤矿已经开采20多年,该矿区的排土场进行了生态修复,使得该地区景观生态发生了显著地变化。通过生态修复工程的实施,排土场生态修复已见成效,对于是否能使该地区生态系统在修复后保持长期稳定,进行了如下研究。本文运用Miami模型,通过计算该地区植被净第一性生产力,对生态系统稳定性研究,得出如下结论:黑带沟露天煤矿所在地区的自然系统本底的生产力处于最低--较低水平,稳定性较差;复垦后稳定性大幅度提升,即生态系统更稳定。

Hei-Dai-Gou open-pit coal mine has been mined for more than 20 years, there has carried out ecological restoration , this make landscape ecology of Hei -Dai-Gou has changed significantly .Through the implementation of ecological restoration engineering , mine ecological restoration has been paid off .But whether can make the region ecosystem keep long -term stability after repair , start the re-search as follows .In this paper , using the Miami model , calculate the area of vegetation net primary productivity researching the ecological system stability.The following conclusions:The productivity of natural systems background lowest -low, stability is poorer.After reclama-tion the stability enhance significantly .the ecological system is more stable .
