【摘要】：水足迹从消费角度建立了水资源利用与人类消费模式的联系,衡量人类对水资源系统的直接占用,是当前测度人类生活和生产活动对水资源生态环境系统影响的最有效的指标之一。本文基于2004-2013年辽宁省14个城市的水足迹面板数据,利用随机前沿分析SFA和数据包络分析SBM方法分别计算了辽宁省14个城市的水资源利用绝对效率和相对效率;通过基尼系数和变异系数来分析水资源效率的动态变化结果显示水资源利用效率差异在不断缩小,且有收敛趋势;借助核密度估计模型,分析了水资源利用效率的动态演变规律。结果表明,近10年间,沈阳、大连、鞍山及盘锦的水资源绝对效率和相对效率水平均较高,阜新和朝阳绝对效率和相对效率均位于全省最低水平;地理位置分布整体呈现中部内陆至南部沿海向东西两侧逐渐递减的特征;辽宁省水资源利用相对效率处在逐渐提高的状态,各城市相对效率值差距在不断缩小。利用聚类分析对水资源利用效率进行时空分异研究,构建了空间权重矩阵,显示辽宁省水资源利用效率存在空间自相关关系;空间集聚分析显示,高高集聚区域主要分布在辽宁省经济水平相对发达的城市,如大连、鞍山、盘锦等地区;低低集聚主要集中在经济欠发达的城市,如阜新、朝阳、葫芦岛;高低集聚和低高集聚一般分布在高高集聚和低低集聚之间。因此,可以通过提高低低集聚地区的水资源利用效率促进提高周围地区水资源利用效率,有利于辽宁省水资源利用效率的整体提高。
[Abstract]:From the perspective of consumption, water footprint has established the relationship between water resources utilization and human consumption mode. It is one of the most effective indicators to measure the direct occupancy of human resources to water resources system, and it is the most effective index to measure the impact of human life and production activities on the water resources and ecological environment system. The water footprint of panel data of 14 city 2004-2013 in Liaoning Province Based on SFA, by using stochastic frontier analysis and data envelopment analysis SBM method of absolute efficiency and relative efficiency of utilization of water resources in the 14 city in Liaoning province were calculated; dynamic change through the Gene coefficient and the coefficient of variation to analyze water resource efficiency results show that the efficiency difference of water resources use in the shrinking, and there is a trend of convergence; kernel density estimation model by analysis of the dynamic evolution law of water resources utilization efficiency. The results show that the past 10 years, Shenyang, Dalian, Anshan and Panjin, the total water resources efficiency and relative efficiency levels were higher, Fuxin and Chaoyang absolute relative efficiency and efficiency are all located in the province's minimum level; the distribution characteristics of the overall presentation of the central inland to the south coast to the East Side West gradually decreasing geographical location; water resources utilization in Liaoning province the relative efficiency in a gradual increase in the state, the city relative efficiency gap is narrowing. By using cluster analysis on the utilization efficiency of water resources spatial differentiation research, constructs the spatial weight matrix, display the efficiency of utilization of water resources in Liaoning province are spatial correlation; spatial cluster analysis showed that high concentration areas are mainly distributed in Liaoning province economy is relatively developed in the city, such as Dalian, Anshan, Panjin and other regions; low agglomeration mainly concentrated in the economically underdeveloped City, such as Fuxin, Chaoyang, Huludao; high and low level of agglomeration agglomeration in the general distribution between the high concentration and low concentration. Therefore, we can improve the utilization efficiency of water resources in low and low concentration areas and promote the efficiency of water resources utilization in the surrounding areas, which is conducive to the overall improvement of water resources utilization efficiency in Liaoning province.
