The main study areas are as follows: 1 The landscape classification system of the urban-rural ecotone is set up based on the studying on land-use type of urban area and rural area, and then it is used to establish a regional landscape data warehouse for deposition, modification and management; 2 A group of landscape structure and pattern indices and patch area spectrum analysis methods are used to describe the structural and heterogeneous characters of all the landscape elements from different aspects; 3 The temporal and spatial difference of the landscape pattern of main road belts of the research area are also analyzed with the same method. Their basic process and regularity of urban axial expanding of the southwestward of Shanghai City are initially knewn well; 4 According to the traits of the ecotone, the principles and basis of vegetation classification, the ecotone vegetation classification system is set up, its species constitute, community patch characters, the relationship between vegetation types and landscape categories are analyzed, meanwhile, the vegetation sample maps are made; 5 Based on above studies, some landscape ecological stratedies within the research area were discussed. The following are the results of this study
