【摘要】 利用水资源生态足迹模型对成都市2000-2015年水资源生态足迹与生态承载力进行了研究.结果表明,成都市历年水资源生态足迹值在2000-2012年呈上升趋势,受成都市节水政策和产业转型影响, 2013年相对降低, 2014年和2015年趋于平缓;水资源生态承载力与降水量呈正相关关系,相关系数达0.952,旱情灾害影响成都市生态承载力水平, 2006年与2009年的干旱使成都市水资源产生生态赤字;万元GDP水资源生态足迹值逐年下降,成都市水资源利用效率16年间增长6.8倍;成都市各区县人均水资源生态足迹分布不均且在2013-2015年变化较大,成都市规划发展的工业城市人均水资源生态足迹值高,各区县处于人均水资源生态盈余状态,但数值逐年下降,水生态安全保障降低;改变产业结构、提高水资源利用效率、增强水利设施对干旱等自然灾害的应对能力是成都市水资源可持续利用的基本途径.更多还原

【Abstract】 Using the ecological footprint model of water resources, the ecological footprint and ecological carrying capacity of water resources of Chengdu from 2000 to 2015 were studied. The results showed that the ecological footprint value of water resources in Chengdu increased from 2000 to 2012 and was relatively low in 2013 due to the influence of Chengdu’s water saving policy and industry transformation and tended to be stabilized in 2014 and 2015. The ecological carrying capacity of water resources was shown to be in a positive correlation with precipitation, r being 0.952. Drought disasters had a significant effect on the ecological carrying capacity, resulting in an ecological deficit of water resources in 2006 and 2009. The ecological footprint of water resources per wan yuan GDP(ten-thousand yuan GDP) declined steadily year by year, and the water use efficiency increased by 6.8 times in the 16 years. The per-capita ecological footprint of water resources in all districts and counties of Chengdu was unevenly distributed and varied greatly from 2013 to 2015. The per-capita water resource ecological footprint of industrial cities was high, and all districts and counties were in the state of per-capita water resources ecological surplus. However, the value decreased year by year, thus resulting in a reduced water ecological security. In conclusion, to change the industrial structure, improve the efficiency of water resource utilization and enhance the capacity of water conservancy facilities to combat drought and other natural disasters are the basic ways for the sustainable utilization of water resources in Chengdu.更多还原
