文摘By the means of 3S technology,the landscape of Beijing was divided into 6 primary landscape types and 18 landscape patch types in the study,and a series of indexes were calculated by models to analyze the special structure of Beijing landscape.The results show: that the forest land is the maximal and basal landscape patch type(area proportion is 42.534%),farmland(28.888%)and construction area(16.639%) are also the main landscape types in Beijing.From landscape patch types and landscape patch categories levels,the landscape patch distributon is centralized,and patch shape is simple,the main landscape patch fractal dimension indexes are under 1.1,so urban landscape pattern is highly influenced by human disturbance.
