Quantify the Landscape Effect of Rural Region Planning Near Metropolis Using High Spatial Resolution Remote Sensing-Case Study in Gaoliying Town in Beijing

The urban fringe which can be seen as a special form of regional ecosystems with a spatial structure gradually from urban to rural areas of transition, has strong heterogeneity and is typical of ecologically sensitive areas. The expansion of city caused wide attention to the landscape effect of the changes. With the help of GIS, we got landscape pattern changes before and after town planning of Gaoliying town in Beijing by using high resolution image and large-scale map. The results showed that landscape shape index, contagion index and Simpson evenness index increased while landscape diversity index reduced. The pattern of reasonable land use would improve and landscape pattern come to perfect. The intensity index of human disturbance increased. Comparing three increase modes of town development, the landscape pattern change of Gaoliying town is peripheral increase mode.
