中文摘要:
      [目的]从水足迹视角剖析平塘县农业经济增长与农业水资源利用耦合作用机理,为喀斯特峰丛洼地生态治理提供参考资料。[方法]利用联合国粮农组织推荐CROPWAT 8.0软件,测算平塘县2002—2015年农业水足迹,运用脱钩理论,分析平塘县2001—2015年农业发展与农业水资源利用脱钩态势。[结果]①2002—2015年平塘县水足迹与生产总值整体上呈波动上升趋势,但其增长率波动性较大; ②从Tapio脱钩弹性指数来看,现阶段农业经济增长与农业水资源消耗关系尚不稳定,农业水资源不可持续性利用状态仍存在; ③2007年为脱钩关系较为理想年份,其次是2008年,协调状况最差是2006,2002—2015年脱钩态势系整体上,呈倒U形变化趋势; ④从面积来看,研究时段弱脱钩面积比重范围为0%~97.9%(2010年最大,2013年其次,2007和2011年最小),强脱钩面积比重范围为0%~100%(2007年最大,2008年其次,2010年最小),衰退脱钩面积比重范围为0%~49.7%(2011年为49.7%,其他年份为0)。[结论]总体上,平塘县农业经济增长与农业水资源利用协调状况不佳。
英文摘要:
      [Objective] From the perspective of water footprint, the coupling mechanism between agricultural economic growth and utilization of agricultural water resources in Pingtang County of Guizhou Province was analyzed in order to provide reference materials for ecological management of karst peak cluster depression.[Methods] Using the CROPWAT 8.0 software recommended by the Food and Agriculture Organization of the United Nations, to calculate the agricultural water footprint of Pingtang County, and using decoupling theory to analyse the decoupling situation between agricultural development and utilization of agricultural water resources in Pingtang County from 2001 to 2015.[Results] ① The water footprint and GDP of Pingtang County from 2002 to 2015 fluctuated and increased, but its growth rate was volatile. ② From the perspective of tapioelasticity index, the relationship between agricultural economic growth and agricultural water consumption is still unstable at the present stage, unsustainable utilization of agricultural water resources still exists; ③ The ideal or optimistic year for decoupling was 2007, followed by 2008. The worst coordination was 2006 year, and the trend of decoupling showed a trend of inverted "U" shape as a whole from 2002 to 2015; ④ In terms of area, the specific gravity range of weak decoupling area during the study period was 0%~97.9%(the largest was 2010, the second largest was 2013, and the smallest was 2011), the specific gravity range of strong decoupling area was 0%~100%(the largest was 2007, the second largest was 2008, and the smallest was 2010), and recession decoupling area specific gravity range was 0%~49.7% (it was 49.7% in 2011, and other years was 0).[Conclusion] Overall, agricultural economic growth and agricultural water use coordination is not good in Pingtang County.
