| Abstract: | Based on the land use data of Fuzhou five districts in 1988,2000 and 2008,supported by the function of GIS spatial analysis,and with the indexes of fragmentation,isolation and dominance,and of vulnerability of landscape types,it was introduced the indexes of ecological security to analyze that temporal characteristic of ecological security.The result shows: the change in landscape structure can strongly influence the indexes of ecological security in the region,which might result in the creasing of the degr... |
