Description :
Supported by the technologies of remote sensing (RS) and geographical information system (GIS), the AA. chose northwest of Beijing as a study area and gave priority to understanding of the spatial-temporal characteristics of landscape pattern change through visually interpreted Landsat TM images of 1989, 1996 and 2005. It is believed that there were a series of landscape ecological problems caused by city expansion. For this reason, this study adopted accumulative cost distance model, combined with ecosystem services and spatial interactions of landscape types, analyzed the spatial difference of the ecological function and the compactness of landscape structure in the study area, and further discussed the landscape pattern optimization proposal. Results are presented in the context of landscape ecological planning in Beijing region : to establish urban ecological corridors and pattern in the course of city expansion.
