The landuse change and landscape heterogeneity in the Dongda coal mine are studied in comparison with no coal-mining subsidence.The changes of patch number and its avreage in various landuses
as well as fragmentation index
diversity index
evenness index
dominance index
and so on are analyzed.Results in- dicate that the development tencJency of ecological environment is unreasonable in the Dongda coal-mining subsidence area because coal-mining subsidence causes distortion of land surface
such as cracks
subsidence hole
and landslide.Consequently
it breaks the cultivated land into small pieces
brings an increase in patch number and a decrease in patch average area
