山西省水资源与经济要素时空协调分析

Spatial and Temporal Coordination Analysis of Water Resources and Economic Development in Shanxi Province

以山西省为研究区域,选取GDP、人口、土地面积3个经济发展要素,建立协调度评价模型分别计算经济发展要素与水资源总量和水资源使用量的协调度,分析两者空间协调特征。结果表明:(1)以水资源总量为评价指标时,水资源丰富地区,协调状况好;(2)以水资源使用量为评价指标时,经济发达地区,协调状况好。分别计算2个水资源指标与各经济要素的基尼系数,分析其时间协调特征,结果表明:水资源总量和水资源使用量与各经济要素的协调状况在2008-2015年间总体波动不大。水资源总量与土地协调性好,而水资源使用量与人口和GDP协调性好。

Taking Shanxi Province as the research area,this paper chooses three economic development elements of GDP,population and land area,respectively,with the total amount of water resources and water resources quantity. The results show that（1） when the total amount of water resources is the evaluation index,the coordination status is better in the areas with abundant water resources.（2） When water resources are used as the evaluation index,the coordination status is better in economically developed areas. Aspects,the Gini coefficients of two water resources indicators and various economic development elements are respectively calculated, and their time coordination characteristics are analyzed. The results show that overall coordination between the total amount of water resources and the amount of water resources used and the various economic development elements fluctuated very little between 2008 and 2015. The total amount of water resources is highly coordinated with the land,while the amount of water used is highly coordinated with the population and GDP.
