摘要
为探究沱江绿色发展经济带水资源利用与经济发展的匹配关系,采用基于数列的匹配度计算方法,研究2011-2022年经济带用水结构与产业结构的匹配状态,研究结果表明:(1)成都市水资源量和用水量最高,分别是最低自贡市的5.82倍和8.44倍,且各市农业用水最高、工业用水下降明显而生活用水呈波动增长;(2)经济带总GDP的年均增速达9.3%,除资阳市以外其余各市生产总值均保持平稳增长,且成都市、内江市、自贡市和资阳市已实现以第三产业为主导的产业结构调整;(3)经济带总用水量与总GDP的空间匹配度处于相对匹配及以上的状态,且空间匹配度大小依次为自贡市(0.99)>内江市(0.97)=泸州市(0.97)>资阳市(0.96)>德阳市(0.87)>成都市(0.78);(4)经济带各市用水结构与产业结构的时间匹配度表现为农业用水与第一产业的匹配度整体高于其他产业,工业用水与第二产业以及生活用水与第三产业的匹配度均出现“不匹配-匹配-不匹配”的转变,这与水资源利用效率的提高和产业结构的转型升级有关.
To investigate the relationship between water resources utilization and economic development in the Tuojiang River Green Development Economic Belt,a matching degree calculation method based on numerical sequences was adopted to analyze the matching status between water use structure and industrial structure from 2011 to 2022.The results indicate that:(1)Chengdu recorded the highest water resources volume and water consumption,which were 5.82 times and 8.44 times higher than those of Zigong(the lowest),respectively.Agricultural water use constituted the largest share across all cities,industrial water use decreased significantly,while domestic water consumption showed a fluctuating upward trend.(2)The average annual growth rate of the total GDP for the economic belt reached 9.3%.Except for Ziyang,all other cities maintained steady GDP growth.Furthermore,Chengdu,Neijiang,Zigong,and Ziyang have achieved an industrial structure transformation dominated by the tertiary sector.(3)The spatial matching degree between total water consumption and total GDP for the economic belt wa s at a relatively matched level or above.The spatial matching degree,in descending order,was Zigong(0.99)>Neijiang(0.97)=Luzhou(0.97)>Ziyang(0.96)>Deyang(0.87)>Chengdu(0.78).(4)The temporal matching degree between water use structure and industrial structure in each city showed that the matching degree between agricultural water use and the primary industry was generally higher than that of other sectors.The matching degrees between industrial water use and the secondary industry,and between domestic water use and the tertiary industry,both exhibited a transition from“mismatch→match→mismatch,”which is associated with improvements in water use efficiency and the transformation/upgrading of the industrial structure.
