摘要:依据2003—2017年全国31个省份面板数据,在测度城市土地和水资源利用效率的基础上,利用耦合协调模型分析两资源利用效率的协同性矛盾性及其时空分异特征,并进一步利用莫兰指数模型分析耦合协调度的空间相关性和空间集聚特征,结论如下:(1)我国城市土地和水资源综合利用效率大体呈现出缓慢上升趋势,但效率值均不高,土地资源综合利用效率呈东部高于东北高于西部高于中部的空间格局,水资源综合利用效率呈东部高于西部,西部高于中部,中部高于东北的空间格局。(2)我国城市土地和水资源利用效率耦合协调整体处于一般耦合协调阶段,以土地资源效率滞后类型为主,耦合协调度时空格局差异显著,呈东部高于西部,西部高于东北,东北高于中部的空间分布格局,东部地区处于良好耦合协调阶段,东北、中部和西部区域均为一般耦合协调阶段。(3)我国城市土地和水资源利用效率耦合协调度呈显著正向空间自相关,主要集聚在"高-高"和"低-低"两个区,具有两极分化趋势。
Based on the panel data of 31 provinces in China from 2003 to 2017,on the basis of measuring the utilization efficiency of urban land and water resources,this paper uses the Coupling Coordination Model to analyze the coordination,contradiction and the spatial-temporal differentiation characteristics of the two resources utilization efficiency.And the Moran index model is also used to analyze the spatial correlation and spatial agglomeration characteristics of coupling coordination degree.There are following findings:(1)The comprehensive utilization efficiency of urban land and water resources in China generally shows a slow upward trend,but the efficiency values are not high.The comprehensive utilization efficiency of land resources shows the spatial pattern of Eastern>Northeast>Western>Central.And the comprehensive utilization efficiency of water resources shows the spatial pattern of Eastern>Western>Central>Northeast.(2)The coupling coordination of urban land and water resources utilization efficiency is in the general coupling coordination stage,and the land resource efficiency lag is the main type.The spatial-temporal patterns are significantly different,showing the spatial distribution pattern of"East>West>Northeast>Central".The eastern region is in a good coupling coordination stage,and the northeast,central and western regions are all in the average coupling coordination stage.(3)The coupling coordination degree of urban land and water resources utilization efficiency in China shows a significant positive spatial auto-correlation,which is mainly concentrated in"high-high"and"low-low"areas,with a trend of polarization.
