摘要
将水资源作为生产要素之一,利用生产函数模型对辽宁省14个城市1998—2008年11年间的用水边际效益进行了估算。采用fuzzy isodata方法根据用水边际效益对14个城市进行聚类,通过聚类中心分析了辽宁省用水边际效益的时间差异,结果表明,辽宁省各城市用水边际效益是在不断的增长,显示出随着经济的发展,水资源的稀缺性在加大,其资源价值在不断提高;借助锡尔指数和基尼系数对辽宁省1998—2008年11年间东中西三大地带用水边际效益的空间差异进行分解,结果表明,区域内差异是造成总差异主要原因,区域间及区域内的差异都呈缩小态势,并逐渐收敛趋同。该结果对辽宁省的水资源可持续利用具有一定的指导作用。
Water resources is the fundamental base for the sustainable development of national economy, which is also an important product factor, the production function was applied to calculate the water utilization margin benefit of 14 cities in Liaoning Province from 1998 to 2008 in this paper. The fuzzy ISODATA method was adopted to cluster the 14 cities into three categories according to the water utilization margin benefit, and the temporal difference was analyzed by the cluster center, the result showed that the water utilization margin benefit was continuously increasing, which reveals the fact that with the development of economy, the scarcity of water resources was enhanced, and the resource value of water resources was increased. The Theil index and Gini coefficient were adopted to decompose the difference of water utilization margin benefit among the west, middle and east regions of Liaoning Province. The result showed that the total difference fits the inversed U shape curve （Kuznets Curve）, and the difference in region was the main cause of total difference, both the difference in region and the difference among regions were decreased. The results have some significance for water resources sustainable development and utilization in Liaoning Province.
