摘要
利用1997年与2002年北京地区遥感资料,对北京六环以内的景观进行分类.用Fragstats3.3计算的景观水平上的各种指数对5年来北京市区的景观格局变化进行分析.结果表明,1997～2002年间北京市区斑块数量增加106.6%,斑块平均大小下降51.6%,分离度指数增加94.3%,景观多样性指数增加17.8%.景观呈破碎化趋势并且景观类型变得多样化.北京市区景观格局变化的驱动力为人口的快速增加和生活水平的提高所带来的房地产用地和城市基础设施用地的快速建设.本文进一步讨论了北京市区景观格局变化对城市生态系统物质流和能量流变化的影响,并结合北京城市规划,为北京市城市发展规划提供一些景观尺度建议.
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 Fragstats3.3 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.
