[Effects of urbanization on landscape pattern of Beijing].
Landscape pattern of Beijing urban areas within the six-ringed road was classified based on 1997 and 2002 remote sensing data. The indices from landscape level were computed using Fragstats 3.3 to study the landscape pattern change of Beijing urban areas from 1997 to 2002. The results showed that the number of patches increased by 106.6%, the mean patch area decreased by 51.6%, the splitting index increased by 94.3%, and the landscape diversity index increased by 17.8%. The landscape pattern tended to be fragmentized and diversified in those five years. The reason of this change was the increased need for construction land due to the growing population and the improvement of living standard. Landscape pattern change of Beijing might influence the changes of substance flow and energy flow. It also provided some fundamental landscape scale data and some suggestions for development and planning of Beijing city.
