摘要:
[目的]以土地利用经济效益、社会效益、生态效益3个维度为支点,从多角度对天山北坡城市群土地利用效益时空分异特征进行探究。[方法]选取2000年、2005年、2010年和2015年4个年份作为研究时点,运用改进熵值法对天山北坡城市群土地利用效益综合水平进行定量测度; 借助耦合协调模型及ArcGIS空间分析软件对其耦合协调水平进行空间显化; 通过GeoDA分析软件对其耦合协调状况进行空间相关性分析。[结果]结果表明:(1)天山北坡城市群土地利用效益综合水平呈逐渐上升趋势且表现出明显的三级阶梯差异特征。(2)天山北坡城市群土地利用效益耦合协调水平整体较低但呈上升态势; 同一研究时点各城市间耦合协调水平差异较大; 耦合协调水平在时空分异中明显较高且相对稳定的是乌鲁木齐市、石河子市、克拉玛依市。(3)天山北坡城市群土地利用效益呈现出负的空间自相关特征且空间布局向节点城市聚类特征明显; 研究时段内出现显著聚集类型的城市只有乌鲁木齐市、昌吉市、石河子市和克拉玛依市。[结论]天山北坡城市群土地利用效益受经济、社会、环境等复杂作用机理影响具有不同时空分异特征。

Abstract:
Based on the three dimensions of land use economic benefit,social benefit and ecological benefit,the spatial and temporal differentiation characteristics of land use efficiency of urban agglomeration on northern slope of Tianshan Mountains were explored from multiple anglesThe years of 2000, 2005, 2010 and 2015 were selected as the research points,and the comprehensive entropy method was used to quantitatively measure the comprehensive utilization level of land use efficiency on the northern slope of Tianshan MountainsThe coupling coordination level is simulated by the coupling coordination model and ArcGIS spatial analysis softwareSpatial correlation analysis was carried out by GeoDA analysis softwareResults showed that:(1)The comprehensive utilization level of land use efficiency of the urban agglomeration on the north slope of Tianshan Mountains is gradually increasing and showed a clear three step difference characteristics.(2)The level of land use benefit coupling in the urban agglomeration of the northern slope of Tianshan Mountains is low,but showed an upward trendAt the same time,the level of coupling coordination between cities was differentCoupled coordination level in the spatial and temporal differentiation was significantly higher and the city of Urumqi city,Shihezi city,Karamay city was relatively stable.(3)The land use efficiency of the urban agglomeration on the northern slope of Tianshan Mountains shows a negative spatial autocorrelation characteristic and the spatial distribution was obvious to the node cityDuring the study period,cities with significant aggregation types were Urumqi city,Changji city,Shihezi city and Karamay cityThe land use efficiency of the urban agglomeration on the northern slope of Tianshan Mountains was affected by the complex mechanism of economy,society and environment,and had different temporal and spatial characteristics.
Key words:  land use efficiency  improved entropy method  coupling coordination  spatial analysis  urban agglomeration on the northern slope of Tianshan Mountains
