【摘要】：以我国大陆地区的30个省(自治区、直辖市)为例,选取其2005~2014年的水资源和能源资源数据,利用重心和标准差椭圆空间统计方法及洛伦茨曲线和基尼系数计算方法,量化分析区域水—能源资源的空间分布特征及匹配格局。结果表明,现状年(2014年)下,水与能源的重心均远离区域几何中心,空间分布均极不均衡;从标准差椭圆看,水资源主要分布区域在我国东南部,面积约249.26×104km2,大致呈东-西走向,能源主要分布区域在我国中北部,面积约113.84×104km2,显著呈东北-西南走向;水与能源间的基尼系数高达0.863,呈极度不匹配的空间格局。2005~2014年,水资源重心由北向南移动,主体走向偏东-西,主要分布区域趋于聚集,空间分布不均衡程度增加;能源资源重心由南向北移动,主体走向偏东北-西南,主要分布区域微弱扩散,南北方能源资源丰度间的差距变大;水与能源在空间上的聚集和分布的差异性增加,不匹配程度在波动中缓慢上升。
[Abstract]:Taking 30 provinces (autonomous regions, municipalities directly under the Central Government) in the mainland of China as an example, the data of water and energy resources from 2005 to 2014 are selected, and the elliptical spatial statistical method of center of gravity and standard deviation, the Lorentz curve and the calculation method of Gini coefficient are used. The spatial distribution and matching pattern of regional water-energy resources are analyzed quantitatively. The results show that in the current year (2014), the center of gravity of water and energy is far away from the geometric center of the region, and the spatial distribution is extremely uneven. From the ellipse of standard deviation, the main area of water resources distribution is in the southeast of China, with an area of about 249.26 脳 10 ~ 4 km ~ 2, which is roughly east-west. The main area of energy distribution is in the central and northern part of China, with an area of about 113.84 脳 10 ~ 4 km ~ (2), and the Gini coefficient between water and energy is as high as 0.863, showing an extremely mismatched spatial pattern from 2005 to 2014, and the center of gravity of water resources moves from north to south. The main body tends to east to west, the main distribution area tends to gather, the degree of spatial distribution imbalance increases, the center of gravity of energy resources moves from south to north, the main body moves toward northeast to southwest, the main distribution region diffuses slightly, The difference of water and energy in spatial accumulation and distribution increases, and the mismatch degree increases slowly in the fluctuation.
