Abstract

Based on remote sensing data, we extracted the dynamic land use/cover change, reconstructed the basic landscape process in Beijing during 1975 to 2001, and predicted the layout of Beijing in the next 20 years using CLUS-S model. After analyzing, we found that: (1) While the sprawl rate of the city was accelerating gradually and the urban area increased sharply between 1975 and 2001, the area of plantation was decreased and the problem of land degradation and fragmentation of the ecological environment was more and more serious; (2) Based on all six simulation scenarios, the area of plantation was going to be reduced gradually, and the integrity of landscape of plantation area was going to be further collapsed with the grads of urban-rural ecotone.
