摘要
[目的]分析长三角地区城市水资源供给对土地利用结构的影响,为制定长三角地区城市水土协调利用政策提供依据,也可为"十三五规划"中节水型社会建设任务的实现提供决策支持。[方法]基于"结构—功能"理论,从城市生产、生活和公共服务三项基本功能出发,分析水资源供给结构对城市土地利用结构变化的影响,并以2001—2014年长三角地区地级及以上城市为样本,构建计量模型。[结果]区域整体范围内,城市生活用水供给量与生活用地规模呈显著的正相关关系,生产用水供给量与生产用地规模也呈正相关关系,而服务用水供给量与公共服务用地规模不显著;就影响程度来看,生活用水与生活用地的回归系数为0.339 3,生产用水与生产用地的回归系数为0.086 7;水资源供给对土地利用结构的影响在不同城市间存在较大差异,城市规模越大,等级越高,其影响也越明显。[结论]研究期内长三角地区水资源供给对生活、生产用地的影响已经显现,并且对生活用地规模的影响远远大于对生产用地规模的影响,而对公共服务用地的影响尚未显现;一旦出现水资源危机,大城市土地资源的开发利用将受到直接影响。
[Objective]This paper mainly analyzed the effect of water resource supply on land use structure.It might provide the bases for the policies with respect to coordinated utilization of urban land resource and water resource in the Yangtze River delta,and for decision support of water-saving society construction of the 13 th Five-Year Plan,as well.[Methods]Based on the theory of structural-functionalism,having the basic functions of urban production,life and public service as core,a mathematical model was built between several pairwise factors,as productive water and productive land,living water and living land,service water and service land in the Yangtze River Delta during 2001—2014.[Results]（1） There was a significant positive correlation between the supply of living water and the scale of living land.And a significant positive correlation between the supply of productive water and the scale of production land was also detected.However,the service water had no significant effect on the service land.（2） The regression coefficient was 0.339 3 between living water and living land,and was 0.086 7 between productive water and productive land.（3） From the regression coefficient,the influence of water supply on living land was much greater than that on productive land.The effect of water resource supply on land use structure was positively correlated with GDP andurban scale rank.In general,a city with more GDP and larger scale might easily undergone severe feedback from water resource supply.[Conclusion]The influences of water supply on the life land and production land both existed.The influence on the public service land had not yet appeared in the Yangtze River Delta.If water resources are becoming scare,the development and utilization of urban land resources will be directly affected in large city.
