【摘要】：为了量化人口、富裕度和技术等因素对膳食水足迹的影响,以全国城乡居民2000—2015年的膳食水足迹为基础数据,采用偏最小二乘回归方法(PLS)对STIRPAT模型进行修正,分析八大区域膳食水足迹的驱动因素,并引入脱钩理论分析了经济发展与膳食水足迹之间的关系。结果表明:(1)2000—2015年期间,全国膳食水足迹呈现平稳增加趋势,华北地区膳食水足迹增加趋势最显著,黄淮海地区膳食水足迹绝对量最大;(2)人口总数对八大区域膳食水足迹有促进作用,城市化率、GDP、膳食水足迹强度、人均粮食产量、耕地灌溉面积对八大区域膳食水足迹影响的促进与抑制作用并存;(3)研究期内,经济增长与膳食水足迹之间的关系大多处于弱脱钩状态,说明膳食水足迹有待降低,尚未达到与经济协调发展的最佳状态。
[Abstract]:In order to quantify the influence of population, abundance and technology on dietary water footprint, STIRPAT model was modified by partial least squares regression method (PLS) based on the dietary water footprint of urban and rural residents in China from 2000 to 2015. The driving factors of dietary water footprint in eight regions were analyzed, and the relationship between economic development and dietary water footprint was analyzed by introducing decoupling theory. The results showed that: (1) from 2000 to 2015, the dietary water footprint of China showed a steady increasing trend, the dietary water footprint of North China was the most significant, and the absolute amount of dietary water footprint of Huang-Huai-Hai area was the largest; (2) the total population can promote the dietary water footprint of the eight regions, and the urbanization rate, the intensity of GDP, dietary water footprint, the per capita grain yield and the irrigation area of cultivated land can promote and inhibit the dietary water footprint of the eight regions. (3) during the study period, the relationship between economic growth and dietary water footprint was mostly in a state of weak decoupling, which indicated that the dietary water footprint needed to be reduced and had not yet reached the best state of coordinated development with the economy.
