摘要
从美丽中国视角深入,选取辽宁省14个地级市为地域尺度,以20092018年为时间尺度,探究人口-经济系统耦合关系及时空演变过程。结果表明:10年间,环境系统与经济系统均呈增长态势,且环境系统增长速度快于经济系统;经济-环境系统耦合度虽不稳定波动,但一直处于高度耦合类型,时间上呈现出“V”和“M”形;空间尺度上,辽宁省14个地级市耦合度差距逐渐增加,沈阳、大连基本保持省内领先地位,盘锦、营口耦合度增加较快,阜新、朝阳等城市还需进一步提高。
Under the perspective of Wild China,the study selects 14 prefecture-level cities as the territory scale,and explores the population-economic system coupling relationship,and the temporal and spatial changing from 2009 to 2018.The results show that,in 10 years,environmental system and economic system both increase,and the increasing speed of environmental system is faster than economic system.Although the coupling of economic and environmental system doesn’t fluctuate unstably,but it is always in highly coupled type.V and M type is represented in time.Difference of coupling in 14 prefecture-level cities in Liaoning Province becomes great in spatial scale,and Shenyang and Dalian remain as the leading position in Liaoning Province.The coupling degree of Panjin and Yingkou increases fast,and Fuxin and Chaoyang need to be improved.
