烟台市土地利用变化碳排放效应分析

摘要

Based on the data of land use change and energy consumption in Yantai during 2005-2014,quantitative analysis of the relationship between land use change and carbon emissions in Yantai during 2005-2014 was conducted.The results showed that carbon emissions ever-increasing of Yantai from 2005 to 2014.The proscess can be divided into four stages:steady growth period(2005-2008),fluctuation period(2008-2012),rapid growth period(2012-2013),fluctuation period(2013-2014).Different land use types play different role in carbon cycle,in which,construction land was the main carbon source,forest land,grassland,garden,water and other carbon sequestration slow,carbon emissions are much faster than carbon sequestration.%基于2005-2014年烟台市土地利用变化和能源消耗等资料,统计分析了2005-2014年烟台市土地利用变化与碳排放量间的定量关系.结果表明,2005-2014年,烟台市排碳量不断增加,可以分为4个阶段:平稳增长期(2005-2008年)、波动期(2008-2012年)、快速增长期(2012-2013年)、波动期(2013-2014年);不同地类固碳与排碳角色不同,其中,建设用地是最主要的碳源,林地、草地、园地、水域等地类固碳慢,排碳比固碳要快得多.
