使用民国34年(1945年)1∶1×104地形图、1968年CORONA影像及近期Landsat5和2015年GE影像数据,使用遥感技术以多元多时相遥感数据融合和GIS挖掘技术为支撑,采用等扇分析法和重心转移矩阵分析了喀什市70 a城市空间形态整体扩展特征,各方向上的扩展速度、强度以及空间重心转移的方向、强度.结果表明:1945-2015年间喀什市空间形态经历了带状扩展向团状扩展的转变,城市整体空间扩展强度不断加剧,空间扩展速度呈先上升后下降再上升的趋势,空间重心向东南方向绿洲腹地转移1 009 m,侵占甚多绿洲耕地,城市空间扩展模式粗放,亟待调整.
Using 34 years (1945) 1: 1 × 104 topographic maps of Republic of China, 1968 CORONA images and recent Landsat 5 and 2015 GE image data, using remote sensing technology based on multivariate multi-temporal remote sensing data fusion and GIS mining technology, Analytic method and center of gravity transfer matrix, the paper analyzes the characteristics of spatial expansion, intensity of expansion and direction and intensity of spatial center of gravity in 70 a cities in Kashgar.The results show that the spatial morphology of Kashgar experienced a The expansion of the spatial expansion of the city first increased and then decreased and then rose again. The center of gravity of the space shifted 1 009 m to the hinterland of southeastern oasis, occupying a large amount of oasis cultivated land and urban space Expanded model extensive, urgent adjustments.
