黄河流域水、土、能资源综合利用效率时空格局分析

Spatial-temporal Pattern Analysis of Comprehensive Utilization Effi⁃ciency of Water, Soil and Energy Resources in the Yellow River Basin

【目的】探究黄河流域水、土、能资源综合利用效率的影响因素,深入了解黄河流域的资源综合利用情况。【方法】通过收集整理统计年鉴相关数据,运用Malmquist全要素生产率指数,对黄河流域2011—2019年70个地级市水、土、能资源综合利用效率变化进行分析。【结果】时间上,黄河流域水、土、能资源综合利用效率的变化趋势为先下降后上升,总体处于上升水平;空间上,黄河流域水、土、能资源综合利用效率呈现出西部地区最高、东部次之、中部地区资源综合利用效率最低;技术进步对资源综合利用效率起着决定性作用。【结论】为黄河流域水、土、能资源综合利用效率的提高,落实黄河流域生态环境保护政策,实现黄河流域经济社会的安全、稳定发展提供参考。

[Purposes]This paper aims to explore the influencing factors of the comprehensive utilization efficiency of water,soil and energy resources in the Yellow River Basin,and to understand the compre-hensive utilization of local resources.[Methods]By collecting and sorting out the relevant data of the sta-tistical yearbook,the Malmquist total factor productivity index was used to analyze the changes in the comprehensive utilization efficiency of water,soil and energy resources in 70 prefecture-level cities in the Yellow River Basin from 2011 to 2019.[Findings]In terms of time,the comprehensive utilization ef-ficiency of water,soil and energy resources in the Yellow River Basin decreased first and then increased,and the overall level was on the rise.In terms of space,the comprehensive utilization efficiency of water,soil and energy resources in the Yellow River Basin in the western region is the highest and that in the eastern region is the second,and the comprehensive utilization efficiency of resources in the central re-gion is the lowest.Technological progress plays a decisive role in the comprehensive utilization effi-ciency of resources.[Conclusions]This paper provides a reference for improving the comprehensive uti-lization efficiency of water,soil and energy resources in the Yellow River Basin,implementing the eco-logical environment protection policy in the Yellow River Basin,and realizing the safe and stable devel-opment of the economy and society in the Yellow River Basin.
