河南省人口与不透水面变化对用水量的影响
Impact of Population and Impervious Surface Changes on Water Consumption in Henan Province
摘要
Abstract
[Objective]To reveal the relationship between population growth,impervious surface expansion,and changes in water consumption,and to provide a scientific basis for the coordinated development of population,land,and water resources in Henan Province.[Methods]Based on panel data and remote sensing data from 2000 to 2022,the intensity difference in-dex,decoupling index,and CCR model of data envelopment analysis were used to measure the intensity of population growth and impervious surface expansion in various cities of Henan Province,and the change trends were analyzed to reveal their in-fluence on water consumption.[Results](1)The intensity of population growth and impervious surface changes in various cities of Henan Province increased.In 2010,the intensity of population growth changed from being higher than impervious surface expansion to being lower than impervious surface expansion.There was a spatial misalignment in the allocation of pop-ulation and impervious surface.(2)At the provincial scale,the relationship between population and impervious surface was consistently characterized by weak decoupling,but the gap between population growth rate and impervious surface expansion rate gradually increased.At the municipal scale,the decoupling relationship between population and impervious surface un-derwent a process from being dominated by ″weak decoupling″ to being dominated by ″weak decoupling and strong decou-pling″.(3)At the provincial scale,the effect efficiency of population was higher than that of impervious surface,and popula-tion growth was the dominant factor driving the increase in water consumption.At the municipal scale,there were regional differences in the effect efficiency of population and impervious surface on water consumption,and the dominance between population growth and impervious surface expansion alternated,demonstrating regional differentiation characteristics.[Conclusion]Population growth and impervious surface expansion both promote an increase in water consumption,but the correlation between population and water consumption is stronger.Henan Province should coordinate the scale and growth rate of population and impervious surface in various cities,adjust water use plans and industrial structures,and achieve the goal of coordinated development of population,land,and water resources.关键词
