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.展开更多
