中国水、能源与粮食空间错位演变与优化路径
Spatial dislocation evolution of China's water,energy,and food and its optimization pathways
摘要
Abstract
The harmonious development of water,energy,and food is a crucial pillar supporting the sustainable development of the economy,society,and ecology.However,influenced by factors such as resource endowment and economic development,the uneven spa-tial distribution of water,energy,and food in China has become increasingly pronounced,gradually emerging as a barrier that constrains their respective development.This study used the standard deviation ellipse and the spatial dislocation index to comprehensively char-acterize the spatial dislocation situation of water,energy,and food in China and its evolutionary trend.Furthermore,four types of spatial weight matrices were constructed,including high-speed rail transportation and market interconnectivity.The spatial Durbin model was then used to analyze the optimization paths of spatial dislocation.The research results indicated that:① From 2005 to 2020,the spatial dislocation of water,energy,and food in China exhibited a two-phase inverted-U shaped pattern.From 2005 to 2015,the spatial disloca-tion intensified continuously,whereas from 2015 to 2020,this trend reached a turning point.In 2020,the resource abundance centers of water,energy,and food in China were located in Hubei Province,Shanxi Province,and Shandong Province,respectively.② From the perspective of spatial distribution patterns,demarcated by the Heihe-Tengchong Line,the spatial dislocation of water,energy,and food exhibited a distinct characteristic of being'strong in the southeast,weak in the northwest.'From the perspective of spatial dislocation degree,from 2005 to 2020,the number of provinces categorized into high,medium,and low dislocation areas evolved from a'triangu-lar'to a'trapezoidal'and finally to a'spindle'shape.③ The main factors influencing the spatial distribution of water,energy,and food in China are natural system factors,such as climate conditions and rainfall,and economic and social system factors,such as talent and industrial structure.These factors influenced the state of spatial dislocation of water,energy,and food through pathways including spatial proximity,transportation interconnectivity,market integration,and industrial complementarity.Based on these findings,it is pro-posed that the construction of railway transportation networks,market opening and integration,and complementary industrial develop-ment should be taken as the starting points for effectively enhancing resource utilization levels,promoting cross-regional collaborative sharing of information technology and other resources,and deepening inter-regional division of labor and cooperation to facilitate indus-trial transformation,thereby alleviating the spatial dislocation of water,energy,and food in China.关键词
