中文摘要	利用遥感和GIS并结合分形理论研究区域城乡空间形态演变,揭示其变化规律,还是一项较为前沿的研究领域.本文集成GIS和分形研究等方法对天山北坡进行了区域和流域两个层面的城乡空间演变研究,初步探究了天山北坡城乡用地扩展方式的时空演变规律,对区域城乡发展的空间研究方法具有一定的指导意义.结果表明该区域城乡空间形态具有较好的分形特征,城市形态分维数由1.238减小为1.234;城镇聚落具有较乡村聚落更为明显的分形特征,分维数依次为市县(1.549)、乡镇(1.236)、村(1.213);城镇用地较农村居民点用地扩展迅速,城镇用地变化指数(0.47)大于农村居民点用地(0.16),城镇用地扩展以外延型为主,城镇化发展较快;城乡用地变化和分形特征均具有明显的空间差异和干旱区绿洲型特征;区域研究和流域研究结果基本一致.
英文摘要	RS、GIS and fractal theory were adopted to study the urban-rural spatial evolution and the rules of change,which was an advanced research field.The urban-rural spatial evolvement in the northern slope of the Tian Mountain was studied from the angle of region and watershed by the GIS and fractal theory.The spatio-temporal evolution patterns of urban-rural land expansion were researched,which had certain instruction meaning for the method of urban-rural spatial study.The main space analytical methods offered by GIS software such as Arc/info, ARCVIEW,MapInfo 6.0 were adopted to analysis data and draw the space shape in urban and rural areas of the remote sensing image;EXCEL was used to count and calculate the fractal dimensions of the space shape in urban and rural areas;Change intensity index was also used to analysis land change.The urban land and the rural settlements were main indexes used in the paper.The studies had positive directive significance for the developing direction of the region.The main results as follows: 1)Urban-rural spatial morphology had a better fractal characteristic,which the eastern section was better than the west section.The urban shape was relatively rule;the urban shape fractal dimension was relatively small,ranging from 1.238 to 1.234.The expansion in urban and rural areas demonstrated oasis type characteristic aridly;2) The fractal characteristic of the city was more prominence than that of the rural,the fractal dimension of cities、towns and villages were 1.549、1.236 and 1.213,respectively;The shape characteristic of the northern slope region in Tian Mountain with simple urban outline,the scale of the cities in the northern slope economy of Tian Mountain was the medium or small-scale at a primary stage;3)The expansion of the urban land use was more quickly than that of rural,the land use change index(0.47) of the cities was larger than that of the rural settlements(0.16),and the land use expansion patterns of cities and towns were mainly outward.The development of the regional urbanization was very fast.;4)The results form the angle of region and watershed were much similarly.The urban-rural land use transformation and fractal characteristic had noticeable spatial discrepancy.The change of the urban land use was mainly take place in Urumqi city,Kuitun city,Shi Hezi city and Changji city,etc.;the land use change of rural settlements happened in the cities such as Miquan,Fukang;the land use expansion and change mainly happened in the key area of the economic belt.
