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。

Firstly, we collected and sorted out the GPS data, established the uniform velocity field for the Chinese mainland and the surrounding regions, and the horizontal deformation field relative to the Eurasia plate; Secondly, we established a motion model for the entire rotation and homogeneous strain of the first and second level blocks in Chinese mainland, analyzed the motion pattern and strain behavior of active blocks in Chinese mainland, as well as the motion pattern of principal fault zones in Chinese mainland; Thirdly, considering the heterogeneity of strain distribution inside a block and supposing that the strain tensor inside the block is the linear function of location, we derived and established an equation for the entire rotation and linear strain of block and a motion model for the entire rotation and linear strain of principal blocks in Chinese mainland; We also calculated the principal strain field and the maximum shear strain field in Chinese mainland and the surrounding regions, analyzed the basic characteristics of strain field in Chinese mainland, as well as the relationship between the spatial distribution of strain field and large tectonic zones; Finally, we established the 2-D geotectonic model and digital model for Chinese mainland and the surrounding regions, calculated the stress field in Chinese mainland and the surrounding regions, and analyzed the basic features of stress field in Chinese mainland and the principal driving force for the motion and deformation in Chinese mainland.

Possible impacts of the tripolar SST anomalies on the decadal scale variability of the North Atlantic climate are also discussed. The dominant mod e of the North Atlantic wintertime SST variability exhibits a meridional tri-polar pattern, with a colder subpolar region, a warmer midlatitudes, and a colder region between the equator and 30°N. Validations on the model performance show that the BCM reproduces the observed NAO pattern and the tri-polar like SST vari ability mode successfully.
