【摘要】：為了量化人口、富裕度和技術等因素對膳食水足跡的影響,以全國城鄉(xiāng)居民2000—2015年的膳食水足跡為基礎數(shù)據(jù),采用偏最小二乘回歸方法(PLS)對STIRPAT模型進行修正,分析八大區(qū)域膳食水足跡的驅(qū)動因素,并引入脫鉤理論分析了經(jīng)濟發(fā)展與膳食水足跡之間的關系。結(jié)果表明:(1)2000—2015年期間,全國膳食水足跡呈現(xiàn)平穩(wěn)增加趨勢,華北地區(qū)膳食水足跡增加趨勢最顯著,黃淮海地區(qū)膳食水足跡絕對量最大;(2)人口總數(shù)對八大區(qū)域膳食水足跡有促進作用,城市化率、GDP、膳食水足跡強度、人均糧食產(chǎn)量、耕地灌溉面積對八大區(qū)域膳食水足跡影響的促進與抑制作用并存;(3)研究期內(nèi),經(jīng)濟增長與膳食水足跡之間的關系大多處于弱脫鉤狀態(tài),說明膳食水足跡有待降低,尚未達到與經(jīng)濟協(xié)調(diào)發(fā)展的最佳狀態(tài)。
[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.
