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

城乡交错带地区的景观分类，在对城市地区和农村地区的土地利用类型研究的基础上建立了城乡交错带的分类体系，并在此基础上用ARC＼INFO软件分时段、分区、分要素建立研究区的景观图形数据库，对数据进行存储、修改和管理；2）利用多种景观结构、格局指数和斑块面积谱分析方法，从不同的侧面对各种景观组分的结构以及区域的景观格局特征进行了分析，并对其成因进行了探讨；3）利用相同的分析方法，分析了城乡交错带中的城市干道两侧的景观格局特征的空间和时间分异情况，初步掌握上海城市西南轴向扩张的基本过程和规律；4）对城乡交错带中非独立的景观要素-植被，研究其遥感图象信息的基本特征，建立适合区域特点的植被分类体系，并在样区中建立了植被图形数据库和计算机制图，分析了植被景观种类组成、斑块等级等特征以及与不同景观的相互关系；5）在上述研究的基础上，对研究区内的景观生态对策进行了研究。
