湖南省2000-2014年碳排放效应及时空格局
Carbon emissions and their spatial-temporal patterns in Hunan Province from 2000 to 2014
摘要
Abstract
Based on the data of land use,energy consumption and the growth of economy and population in Hunan Province during 2000-2014,a carbon emission model based on carbon emission coefficient and decoupling analysis were used to analyze carbon emissions and their spatial-temporal patterns and the decoupling relationship between economic development and carbon emissions.The following findings were obtained:(1) The net carbon emission increased rapidly from 2040.91× 104 t in 2000 to 10902.56× 104 t in 2014,with an average annual increase of 590.78×104 t.(2) The carbon emission per unit area of land and carbon emission per unit area of construction land were 5.15 and 62.55 t · hm-2,with an average annual growth rate of 13.15%and 8.98%,respectively.(3) The net carbon emissions of all lands,carbon emission of construction land,carbon emission per unit area of land,carbon emission per unit area of construction land and carbon emission of GDP per capita had significant spatial differences among 14 cities in 2014,with a decreasing trend from central and east to west part.(4) There existed a reversed U-shaped curve between carbon emission intensity and GDP per capita,with an inflexion point of the curve at roughly 10000-11000 yuan per capita.(5) The elastic characteristics of carbon emissions,energy consumptions and economic growth mainly showed weak decoupling,strong decoupling,and expanded negative decoupling states in Hunan Province during 2000-2014.In general,the elastic characteristics were weak decoupling.关键词
