So,the massive data acquired in the period from January to December in 2006 and authorized by CAIDA Skitter project were used to analyze the searched topological data at CAIDA(cooperative association for Internet data analysis) router level,thus describing the characteristics of the distribution of the degree s of nodes at router level.
针对目前对路由层面的Internet拓扑研究较少的问题,基于2006年1月至2006年12月采集的CAIDA Skitter项目授权的海量数据,对CAIDA路由层面拓扑探测数据进行了分析,描述了路由级节点度分布的幂率性。在此基础上计算出了更能体现网络拓扑层次性的各节点的核数,描述了节点核的幂率分布性质,进一步分析了节点核数与度之间的关系。研究表明,对低核节点,其度分布存在着幂率性质

Beijing is provided with typical urban landscape, forest land is the maximal and basal landscape patch type (area proportion 42.534%), glebe field (28.754%),spinney land and urban (26.912%) and town residential landuse (10.344%) are main landscape patch categories in Beijing. From landscape, landscape patch types and landscape patch categories levels, landscape patch distributing centralize, and patch shape is simple, main landscape patch fractal dimension indexes are under 1.1, so urban landscape pattern is high influenced by human disturbance.2. From 1985 to 2007, Beijing landscape pattern variational characteristics are as follows:(1) During 1985-2007, patch types and categories change is little, but area and patch number of patch types and categories change distinctly. Town residential landuse area increased 7.66% of Beijing total area, farmland and forest land area decrease in the mass. The total patch number increased at first then decreased. taking one with another, the total number is decreasing, and patch number of farmland and forest land are most distinct.
本研究的主要研究结果如下:1、北京市具有典型的城市景观特征,林地用地的面积占市域面积的42.534%,为基质景观斑块类型,旱田(28.754%)、灌木林(26.912%)、城镇用地(10.344%)是北京市主要景观斑块种类;从景观、景观斑块类型以及景观斑块三个层次的研究均表现出北京市各景观斑块类型及景观斑块集中分布的现象十分突出,斑块形状简单,主要景观斑块种类的景观分维度指数值均不足1.1,表明城市景观格局受到了较大的人为影响。2、北京市1985-2007年间城市景观格局的主要变化特征表现为以下几个方面:(1)在研究时段内,北京市景观斑块种类变化不大,景观组分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虽呈波动变化但总体呈减少趋势;景观斑块数量先增后降,总体呈下降趋势,其中耕地与林地斑块数的变化最为明显。
