Analysis on Landscape Fragmentation of Coastal Wetlands Along South Coast of the Laizhou Bay

In this paper,the landscape characteristics and landscape fragmentation of coastal wetlands along south coast of the Laizhou Bay are analyzed using remote sensing and GIS techniques.It is shown from the analysis results that the coastal wetlands in the area have undergone severe fragmentation with a patch density of 6.7 ind./km~2 and a corridor density of 0.01 km/hm~2,the fragmentation degree of artificial landscape is higher than that of natural landscape,and the human activities are the main cause for the landscape fragmentation of coastal wetlands in the area.Finally,the quantitative evaluation of degradation level of coastal wetlands along south coast of the Laizhou Bay is made.
