摘要
利用GIS和景观生态学方法研究武汉市1995～2000年土地利用景观格局变化的特点。结果表明,1995～2000年,武汉市耕地、林地和其他用地的面积在减少,而水体、居民及工业用地的面积在增加;居民及工业用地的斑块密度最大,破碎化程度最高;研究区景观的复杂性在增加,斑块分布均匀程度在降低。研究还发现,景观变化在空间分布上具有一定的规律性。
With GIS and landscape ecology methods,the characteristics of the change of the landscape patterns of land-use in Wuhan were studied.The results showed that the area of the cropland,woodland and other lands were decreased while the area of the water body,cultural residences and industry land were increased form 1995 to 2000.The mean patch size and heterogeneity of cultural residences and industry land were the highest.The complexity of the landscape was increased while the evenness was decreased.Finally,the spatial distribution of the changed patch in landscape was regular.
