摘　　要： 基于3S技术,运用景观生态学原理与方法,在对城区公园绿地景观进行分类的基础上,选取了景观破碎度、景观多样性、景观优势度、景观均匀度等指数对北京市城区公园绿地的景观格局进行了分析。结果表明:北京市区内共有公园绿地斑块105个,绿地面积5 565.74 hm^2,占城区总面积的4.07%。绿地面积以面积大于50 hm^2的大型斑块为主,占总绿地面积的77.66%,缺少社区公园等小型斑块绿地。公园绿地斑块密度为1.89个·km^(-2),景观多样性指数为0.78,优势度指数为0.83,均匀度指数为0.49。绿地斑块景观分布不均衡,分布不合理,景观多样性指数较低。 Based on the ＂3S＂ technique, according to the principles and methods of landscape ecology, were classified. Patterns of green landscapes in the parks in the city proper of Beijing were analyzed by applying the indices such as fragmentation, landscape diversity, landscape dominance, and landscape evenness. It was concluded that there were 105 patches of urban park green lands in Beijing with an area of 5 565.74 hm^2 , accounting for almost 4.07 %of the whole urban area. Large patches with an area of more than 50 hm^2 accounted for 77. 66% of the total area, and there was a lack of small patches such as community parks. The patch density was 1.89 path · km^-2. The landscape diversity, dominance, and evenness indices were 0.78, 0.83, and 0.49 respectively. The distribution of the landscape was uneven, the structure was not reasonable, and the landscape diversity index was low.
