摘　　要：分析不同时期城市的生境质量变化,研究城市土地利用方式对生境质量的影响,对于区域可持续发展具有重要作用。以兰州地区为例,采用InVEST模型测评其生境质量和生境稀缺性。结果表明:2000—2015年,研究区域边界生境存在退化迹象,生境质量分布呈现与土地利用类型格局相似的集聚特征,区域总体生境质量稳定,变化频繁且生境类型稀缺的区块主要表现在草地。Analyzing the changes in urban habitat quality under different periods of administrative planning,and studying the impact of urban land use on the habitat quality,play an important role in regional sustainable development.Taking Lanzhou area as the research area,the InVEST model is used to evaluate its habitat quality and habitat scarcity.The results show that from 2000 to 2015,there were signs of degradation in the boundary habitats of the study area.The distribution of habitat quality showed agglomeration characteristics similar to the pattern of land use types.The overall habitat quality of the area was stable,and the areas with frequent changes and scarce habitat types are mainly manifested in grassland.
