| 摘 要： | 以山西省东大煤矿为例，对采煤沉陷区沉陷前后土地利用状况的变化以及景观异质性进行了初步研究。主要分析了不同土地利用类型斑块数量、面积的变化，以及景观破碎度、多样性、均匀度、优势度等指标。研究结果表明，采煤沉陷造成地表移动变形产生的裂隙、陷坑、塌方或滑坡等，致使土地被分割破碎，斑块数量增加而面积减小，植被毁坏，生态环境向着不合理的方向发展。

| Abstract: | 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 indicate that the development tendency 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, and severely destroys vegetation in the region. |
