摘要:

水资源短缺已成为制约滇中城市群发展的主要因素之一,客观认识水资源生态承载力及其平衡性是解决滇中城市群缺水问题和实现区域社会-经济-生态协调发展的前提。运用水资源生态足迹模型、基尼系数以及重心模型对滇中城市群水资源生态承载力的供需平衡、时空平衡以及平衡性的偏离程度进行分析。结果表明:①2006-2014年滇中城市群水资源生态承载力为(0.216~1.370)hm2/人,区域内部差异和年际变化较大;②水资源生态承载力在供需上呈现不平衡状态,在时间变化上呈现不稳定状态;③水资源生态承载力的综合基尼系数为0.372~0.626,总体上处于“集聚程度较大”的区间范围,空间变异系数为0.358~0.804,水资源生态承载力在空间分布上不平衡;④滇中城市群水资源生态承载力重心与其几何中心偏离,偏向南部地区,年均偏移距离为40.6km,区域间水资源生态承载力与人口、经济分布以及资源环境极不对应。

Abstract:

One of the major constraints restricting expansion of central Yunnan urban agglomeration is that of water shortage. Determining the ecological carrying capacity of water resources for central Yunnan urban agglomeration is needed to solve water shortages and achieve coordinated development of the regional society,economy and ecology. This study used the water resource ecological footprint model,Gini coefficient and gravity model to analyze equilibrium state,time and space,and the degree of deviation of the balance of water resources and ecological carrying capacity for central Yunnan urban agglomeration. We found that the ecological carrying capacity of water resources varied from 0.216 to 1.370 ha per person between 2006 and 2014,with great regional differences and inter annual variation. The ecological carrying capacity of water resources is unbalanced for supply and demand,showing temporal variation in an unstable state. The Gini coefficient of the ecological carrying capacity of water resources varied from 0.372 to 0.626 between 2006 and 2014,within the range of a great distance;the coefficient of spatial variation of the ecological carrying capacity of water resources varied 0.358 to 0.804 between 2006 and 2014,showing the imbalance of regional space as a whole. The center of gravity of water resources and ecological carrying capacity in the central Yunnan urban agglomeration deviates from its geometrical center,which is the southern region,tending to average annual offset distance of 40.6 km,and the ecological carrying capacity of water resources in the region does not correspond to population,economy or resource environment.

Key words: water ecological footprint, ecological carrying capacity of water resources, Gini coefficient, center-of-gravity mode, balance, the central Yunnan urban agglomeration
