摘要：以北京市市域为研究对象,基于1985、1995、2000、2007年北京市Landsat—TM遥感影像,利用景观格局指数分析了研究期间北京市景观格局的变化及特征。结果表明:在1985—2007年时段内,北京市景观格局中景观斑块种类变化不大,景观组分的面积和斑块数变化明显,其中最为显著的是北京市城镇建设用地面积呈单纯的增加趋势,增加幅度为北京市总面积的7.66%,农业用地与林地的面积呈现波动变化但总体呈减少趋势;景观斑块数量先增后降,总体呈现下降趋势,其中耕地与林地斑块数的变化最为明显;自然、半自然斑块受到人工斑块的影响严重,人为干扰的影响使北京市各景观斑块种类分布趋向集中;景观斑块形状更加简单、有规律,表现最为明显的是北京市景观格局中主要的景观斑块种类和斑块类型,从而导致在景观水平上北京市景观指数变化明显,城市化过程对北京市景观结构产生了显著的影响。
A study was conducted to investigate the dynamic changes of landscape patterns in Beijing City in terms of landscape pattern indexes based on the Landsat-TM images in 1985, 1995, 2000, and 2007. Results showed that the patch types changed little, and component area and patch numbers changed significantly. Among all the land use patterns, urban built-up area increased by 7.66% of the total area, and farmland and forest land decreased gradually. The total patch number increased first and then decreased, indicating a decreasing tendency in total. The patch number of arable land and forest land increased obviously. Natural and semi-natural patches were highly influenced by human disturbance. The distributions of landscape patch types tended to aggregate due to human disturbance. Patch shapes are more simple and regular especially for the main landscape patch patterns, which result in an obvious change in landscape pattern indexes. Urbanization process has a significant impact on landscape patterns in Beijing.
