摘要
With the help of 1∶20 000 satellite image of Kunming City and its satellite remote sensing image with resolution ratio 10 m, based on statistic data from Greening Department of Wuhua District and data collected through field study, by making use of landscape ecological theory and methods, the paper had selected three indexes reflecting landscape spatial characteristic including average patch area, landscape fragmentation and landscape connectivity, to analyze landscape spatial characteristic of urban green land. And then it obtained that urban green land of Wuhua District was dominated by small patches, and patches' average area was small; urban green patches were small and fragmented, and landscape fragmentation was high; landscape connectivity was weak and ecological corridor was narrow, failing to bring ecological effect of landscape corridor into full display. Finally, in view of these problems, it had proposed suggestions for optimization, so as to provide reference and theoretical guidance for optimizing and creating excellent landscape spatial characteristic of urban green land in Wuhua District and constructing landscape pattern of ecological security.
