摘　　要：对哈大走廊城市规模—紧凑度—土地集约度的耦合协调度进行了计算,并运用GIS工具中的空间自相关、冷热点分析及变差函数分析法,深入研究了耦合协调度的空间分布特征与演变趋势。研究发现,哈大走廊城市规模—紧凑度—土地集约度的耦合协调性在研究期内整体呈上升态势,三者之间的作用强度与协同效应逐步加强。空间分布具有明显的空间聚集特征,并且自相关性不强,高值区主要集中在东北部和西南部,中部为低值集聚。耦合协调度的空间变异随机性增强,空间差异在不断降低,但结构化分异有增加趋势,东北—西南方向的空间差异最大,南—北向的空间差异最小。The study is calculated the coupling coordination degree among the urban scale, compactness and land intensive utilization degree in Harbin-Dalian urban corridor. Then make a study of the spatial distribution characteristics and evolution trend of coupling coordination degree with the help of method of spatial autocorrelation, hot spot analysis and variogram. The study found that the coupling coordination degree has a tendency to rise in Harbin-Dalian urban corridor. And the strength and synergistic effect among the urban scale, compactness and land intensive utilization degree are gradually strengthened. The spatial distribution has obvious spatial clustering characteristics. And the self-correlation is not strong. High value area is mainly concentrated in the northeast and southwest, and the middle is low concentration. Spatial variability of coupling coordination degree is continually growing and space differences is falling down. But the structural differentiation has increased. The spatial difference of the northeast-southwest direction is the maximum, and the south and the north is the minimum.
