研究结果表明:(1)2001-2010年间,研究区的景观生态质量变化明显,稳定和较稳定的地区由2001年80.66%增加到2010年的90.61%,不稳定地区减少了9.54%,总体呈变好的趋势;(2)研究区景观生态质量变化差异显著,变好和略微变好的地区占总面积的29%,主要分布在破坏较少的山区和土地复垦后的采煤塌陷区,表明土地复垦项目对矿区生态环境起到了一定的改善作用。

The research study showed that: (1) During 2001 to 2010, the landscape ecological quality changed a lot in experiment area. The stable and relatively stable area increased from 80.66% in 2001 to 90.61% in 2010 while unstable area decreased by 9.54% so the entire situation was in better trend. (2) The differences of changes among landscape ecological quality in experiment area were obvious. The better and slightly better area took up 29% of total area, which were focused on less-destruction mountain area and mining collapse area after land reclamation so it showed that land reclamation had certain improvement in mining ecological environment.
