In this paper,three Landsat TM images(obtained in 1989,1993 and 1997) and SPOT5 image(in 2004)were interpreted as basic information sources.With the support of remote sensing and GIS techniques,the classification system of landscape of the region was established; this study area was divided into 3 primary landscape types and 10 secondary landscape types.Spatial information database of landscape was created,and the basic data including properties and graph were analyzed.Selective indexes reflecting the spatial pattern were chosen based on the theory of landscape ecology,by calculation and analysis of these indexes,the dynamic change characteristics of landscape spatial pattern over the past 16 years were studied.The results show that the spatial pattern of landscape in Xiang'an District has been obviously changed.From 1989 to 2004,cultivated land seriously decreased,and the landscape pattern,which was dominated by agriculture and forest in 1989,gradually transformed to artificial landscape,such as residential area and construction land.The patch area of artificial landscape such as land for towns and villages has been increasing,and their patches have been congregating.Aquaculture industry was rapidly expanding,a great of silt beach and shallow sea shore were reclaimed.The regional landscape was becoming more fragmental,diversity index and fragmentation index increased continuously,it was due to the increase of human disturbance.The regional landscape develops towards artificialization,at present the study area has been changed to mixed landscape.Meanwhile,the change of regional landscape pattern has caused a series of landscape ecological effects,such as environmental quality degradation,landscape patch fragmentation,etc.
