水资源与社会经济发展要素时空匹配特征——以张家口为例

水资源短缺已成为制约区域经济社会发展的重要因素,协调水资源与社会经济关系是水资源可持续利用的关键。以张家口为例,采用洛伦兹基尼系数和不均衡指数模型对水资源与社会经济发展要素的时空匹配特征进行研究,结果表明：2004—2015年张家口水资源与人口、耕地面积分布处于“匹配比较合理”和“相对匹配”状态,水资源与经济布局匹配呈现出由“完全不匹配”状态逐渐转变为“相对不匹配”状态。在空间匹配演化方面,水资源与人口、耕地面积的匹配度变化不大。水资源与经济匹配结果表明在水资源禀赋越差的地区,经济增速越快,水资源与经济的空间匹配状况越差。张家口水资源与社会经济发展要素时空匹配特征研究,对于指导区域水资源合理开发利用具有重要的现实意义。

Spatiotemporal matching between water resources and social economy: A case study in Zhangjiakou

Water shortage has been become a vital restricted factor for developing of regional socio-economy. It is critical to harmonize the relationship between water exploitation and socio-economic development so as to achieve sustainable utilization of water resources. In this paper, we take Zhangjiakou as a case study, and adopt the Lorenz Gini coefficient method and imbalance index model to examine the spatiotemporal matching between water resources and socio-economy. The results indicate that the match status between water resources and population, and between water resources and farmland, were reasonable and relatively reasonable respectively from 2004 to 2015. The match status between water resources and economy was changing from complete to relative mismatch. In terms of spatial matching, there was little change of matching between water and population, and between water and farmland. The less water resources there are in a region, the faster economic development is, and the worse the matching between water and economy. This study is important for the development and utilization of water resources in the study area.
