摘要
运用景观生态学的原理与方法,基于GIS技术对芜湖市绿地空间格局特征进行了分析。结果表明,芜湖市绿地景观多样性指数为1.1556、优势度为3.4775、均匀度为0.4977、破碎度为0.4046;城市绿地系统内部景观多样性偏低,优势度明显,类型分布不均,城市绿地生态功能较弱,易受人类活动影响,总体绿地空间布局有待改善。
Utilized the theories of landscape ecology, researched on the spatial structure of urban green land in Wuhu based on GIS technology. The results indicated that the landscape indexes diversity, dominance, evenness ,fragmentation were 1.1556,3.4775,0.4977,0.4046 in Wuhu City. The landscape diversity of urban green land was on the low; the dominance was prominent. Both the spatial arrangement of green land and the kinds of green land were unreasonable. The ecological function of green land was weak, easily influenced by human activity.
