摘要: 结合SEEA理论与方法,核算了中国西部城市——西安市1997-2009 年的主要资源环境成本,基于市、县2 级尺度探究其时空差异性,并计算了资源环境成本占GDP比例情况.结果表明:① 按1990 年可比价,西安市资源环境成本由177197.9 万元增大到396031.8 万元,年均增长率10.29%,高于同期GDP (7.25%) 增长率.② 资源耗减成本大于环境退化成本,但前者比重有所降低,由84.84%降为69.45%.③ 各区县占总成本比例差异明显.2009 年,占西安市资源环境成本比重大于15%的是雁塔区,居于10%~15%的是未央区、莲湖区、户县;居于5%~10%的是新城区、碑林区、长安区、灞桥区、临潼区;其他区县小于5%.④ 据资环密度可将西安市分为3 个圈层:碑林区、新城区、莲湖区属于I 圈,灞桥区、未央区、雁塔区属于II 圈,其他各区属于III 圈;资环密度I 圈集聚、II 圈和III 圈渐次降低;资源环境成本总量I 圈最小,II 圈和III 圈比重相当;按组分分析,能源耗减成本总量在I 圈较低,II 圈和III 圈较高,耕地耗减成本主要产生于II 圈和III 圈,污染成本I 圈< II 圈< III 圈,生态成本集中于III 圈.⑤ 资源环境成本占GDP比例1997 年为7.58%,2005 年达到11.27%,之后降低,2009 年降为9.05%,呈现出环境库兹涅茨曲线特征,空间上I 圈< II 圈< III 圈.

Abstract: This paper accounted the main components of resources depletion value & environmental costs (R-E cost) of Xi'an city in western China from 1997 to 2009 based on SEEA, analyzed temporal and spatial differences of R-E cost at city and county scales respectively, and calculated the ratio of R-E cost to GDP. The results are obtained as follows. (1) The R-E cost of Xi'an city has soared from 1.771979 billion yuan RMB to 3.960318 billion yuan RMB at comparable prices of 1990, with an annual rate of 10.29%, more than the GDP growth rate (7.25%) of the same period. (2) Resources depletion value is higher than environmental degradation cost. The proportion of resources depletion value reduced from 84.84% to 69.45%; (3) R-E cost proportion of each county was different. In 2009, Yanta District accounted for over 15%, Weiyang District, Lianhu District and Huxian County had 10%-15%, Chang'an, Baqiao and Lintong districts had 5%-10%; other counties took up less than 5%. 4) The R-E cost distribution can be divided into three circles according to cluster analysis of R-E density. Beilin, Xincheng and Lianhu districts are located in circle I, districts of Baqiao, Weiyang and Yanta are situated in circle II, and other counties are in circle III. The density of R-E cost in circle I is much higher than that in circles II and III. However, the amount of R-E cost in circle I is much lower than that in circles II and III. Energy consumption cost in circle I is lower than that in circles II and III. Land consumption cost occurred mainly in circles II and III. Pollution cost is listed in the order of circle I < circle II < circle III, and the ecological cost is mainly observed in circle III; 5) R-E cost accounted for 7.58% of GDP in 1997, this figure was up to 11.27% in 2005 and fell to 9.05% in 2009, presenting a "Kuznets curve" pattern; the ratio of R-E cost to GDP is listed in the order of circle I < circle II < circle III.
