Beijing is provided with typical urban landscape, forest land is the maximal and basal landscape patch type (area proportion 42.534%), glebe field (28.754%),spinney land and urban (26.912%) and town residential landuse (10.344%) are main landscape patch categories in Beijing. From landscape, landscape patch types and landscape patch categories levels, landscape patch distributing centralize, and patch shape is simple, main landscape patch fractal dimension indexes are under 1.1, so urban landscape pattern is high influenced by human disturbance.2. From 1985 to 2007, Beijing landscape pattern variational characteristics are as follows:(1) During 1985-2007, patch types and categories change is little, but area and patch number of patch types and categories change distinctly. Town residential landuse area increased 7.66% of Beijing total area, farmland and forest land area decrease in the mass. The total patch number increased at first then decreased. taking one with another, the total number is decreasing, and patch number of farmland and forest land are most distinct.

The results showed that the spatial characteristic of spectra on the opencast coal mine varied with land type area distribution, and landscape pattern. The first and second principal components of the TM images had obvious spatial characteristic, i.e., the first principal component highlighted the characters of excavation and transportation area, slope area, and cumuli and stripping area, while the second principal component highlighted the information of higher and lower vegetation-cover area.
