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. |
