2005—2017年我国人口与生态环境压力、能源消耗的脱钩关系研究

Decoupling Relationship between Population and Ecological Environment Pressure,Energy Consumption in China from 2005 to 2017

基于我国人口、环境、能源数据,运用脱钩理论与方法,对2005—2017年我国人口与生态环境压力、能源消耗的脱钩关系进行研究。结果表明:2005—2017年间,我国人口总量、人口城镇化率、能源消耗总量皆呈上升态势,生态环境压力有所缓解;2005—2017年间我国人口总量与生态环境压力间的脱钩关系主要表现为强脱钩,为理想状态,仅有华北、华南和西南部部分地区为不可取状态;人口城镇化率与生态环境压力间的脱钩关系主要表现为强脱钩,为理想状态,仅有华北、东北和西南部部分地区为不可取状态;人口总量与能源消耗总量间的脱钩关系主要表现为扩张负脱钩,为不可取状态,仅有华东部部分地区为较理想状态;人口城镇化率与能源消耗总量间的脱钩关系主要表现为扩张负脱钩,为不可取状态,仅有西南部小部分地区为理想状态,表现为弱脱钩关系。

Based on the data of population,environment and energy,the decoupling relationship between population and ecological environment pressure,energy consumption in China from 2005 to 2017 was analyzed by the method of decoupling.The result showed that:(1)The population gross,population urbanization rate and energy consumption were increased,and the pressure of environment was alleviated from 2005 to 2017;(2)The decoupling relationship between total population and ecological environment pressure in China was mainly for strong decoupling,which was ideal.Only parts of north China,south China and southwest showed inadvisable.The decoupling relationship between population urbanization rate and ecological environment pressure in China was mainly for strong decoupling,which was ideal.Only parts of north China,northeast and southwest showed inadvisable.The decoupling relationship between total population and energy consumption in China was mainly for expansion negative decoupling,only little parts of east China showed ideal.The decoupling relationship between population urbanization rate and energy consumption in China was mainly for expansion negative decoupling,only little parts of southwest showed ideal,which mainly for weak decoupling from 2005 to 2017.
