中文摘要:
      近年来关中地区发展迅速,对水资源较为贫乏的关中地区带来了巨大的挑战,对关中地区的用水效率进行分析十分必要,本文选取了近10年(2004-2013年)的产值和用水量以脱钩分析的方法和万元产值用水量指标进行综合比较分析,发现关中地区经济增长迅速,用水效率在不断提高,总体上优于全国平均水平,但距离发达国家仍有差距,其中第一产业用水效率不断提高,且对整体影响巨大;第二产业进步显著,趋势有所减缓;第三产业是万元产值用水量最少的产业,但其指标呈回升趋势并出现了扩张性复钩的情况,需引起重视。建议采取有效措施合理产业布局,提高关中地区的用水效率。
英文摘要:
      In recent years, the rapid development in Guangzhong region has brought enormous challenge to this region of poor water resources. Therefore, it is necessary to analyze the water efficiency of Guangzhong region.This article compared and analyzed the output value and water consumption index comprehensively for nearly a decade (2004-2013) by using disconnected analysis method and water consumption of output valued per 10 thousand yuan.The paper found that Guanzhong region's economic growth is rapid and water use efficiency has been consecutively improved, on the whole the economy of the region is better than that of the national average level, but there is still gaps compared with developed countries.The water efficiency in primary industry has been continuously improved,which has great influence on the whole; the secondary industry is improved significantly but the trend has become slow;the third industry is one with the least water consumption of output valued per 10 thousand yuan, but the index has showed a rising trend and appears the emergence of expanding multiple hook which should arouse vigilance. It is recommended to take effective measures to make reasonable industrial layout and to improve water use efficiency in Guanzhong region.
