Effects of Different Land Use Patterns on Carbon Emission in Guangyuan City of Sichuan Province
摘要
Abstract
The effects of land use on carbon emission in Guanyuan City are analyzed.Coefficients of carbon emission of land use were firstly summarized.According to the data of land use,energy consumption and carbon emission coefficients,carbon emission related to land use from 1990 to 2010 were then evaluated.Results are as follows：（1） carbon emission amount increased rapidly from 21 100 thousand tons in 1990 to 39 800 thousand tons in 2010;（2） construction land was a major carbon emission source,whose carbon emission increased from 27 300 thousand tons in 1990 to 49 100 thousand tons in 2010,accounting for about 99% of overall carbon emission;（3） woodland is a major carbon sink,absorbing much carbon from 1990 to 2010,while grassland,water and unused land do not possess carbon sink ability;（4） in terms of the spatial carbon emission pattern,Lizhou district,the center district of Guangyang City,had the biggest carbon emission amount as compared with other places,reaching 16 000 thousand tons per year.Based on relevant research results,some suggestions are presented for reducing carbon emission in Guangyuan City.关键词
