在相关能源消费和土地利用面积数据基础上,采用碳排放模型的研究方法,分析贵州省2001-2010年不同土地利用方式的碳排放效益和时空格局。结论如下:贵州省碳排放总量2001-2010年以来总体呈增长的趋势,年均增加295.56万t ;建设用地的碳排放贡献率达96.86%以上,且呈递增趋势;2001-2010年贵州省碳排放强度总体呈下降趋势,由2001年的2.21万t ·亿元-1下降到2010年的1.21万t ·亿元-1,下降率为6.95%,远小于16.85%的GDP增长率;碳排放收支不平衡,造成生态赤字;2010年,贵州省净碳排放量存在明显的区域差异,总体上呈现出从西到东逐渐减小的趋势,其中六盘水市、黔西南州属于高排放-低效率(HE-LE)类型,黔东南州、铜仁市、遵义市、安顺市属于低排放-高效率(LE-HE)类型,贵阳市、黔南州、毕节市属于中排放-中效率(M E-M E )类型。
在相關能源消費和土地利用麵積數據基礎上,採用碳排放模型的研究方法,分析貴州省2001-2010年不同土地利用方式的碳排放效益和時空格跼。結論如下:貴州省碳排放總量2001-2010年以來總體呈增長的趨勢,年均增加295.56萬t ;建設用地的碳排放貢獻率達96.86%以上,且呈遞增趨勢;2001-2010年貴州省碳排放彊度總體呈下降趨勢,由2001年的2.21萬t ·億元-1下降到2010年的1.21萬t ·億元-1,下降率為6.95%,遠小于16.85%的GDP增長率;碳排放收支不平衡,造成生態赤字;2010年,貴州省淨碳排放量存在明顯的區域差異,總體上呈現齣從西到東逐漸減小的趨勢,其中六盤水市、黔西南州屬于高排放-低效率(HE-LE)類型,黔東南州、銅仁市、遵義市、安順市屬于低排放-高效率(LE-HE)類型,貴暘市、黔南州、畢節市屬于中排放-中效率(M E-M E )類型。

Based on the statistic area data of land utilization and energy consumption from 2001 to 2010 in Guizhou Province ,we analyzed the effects of land uses on carbon emissions and their spatial-temporal patterns in Guizhou province by using carbon emission model .The conclusion could be drawn as follows :The total carbon emission was increasing with an annual rate of 2.9556 × 106 t from 2001 to 2010 ;The carbon emission by construction land had been contribution reaches above 96.86% ,and there was an increasing trend ;Carbon emission intensity decreased continuously ,from 2.21 × 10-4 t · Yuan-1 in 2001 falling to 1.21 × 10-4 t · Yuan-1 in 2010 , with an annual decreased rate of 6.95% ,lower than the increase rate of GDP which was 16.85% ;Carbon emission payment imbalance ,which caused ecological deficit ;There were obvious differences in net carbon emission in 2010 ,with a gradually reducing trend from west to east .Liupanshui ,southwest of Guizhou were the type of HE-LE (High emission-Low efficiency) while southeast of Guizhou ,Tongren ,Zunyi and Anshun were LE-HE (Low emission-High efficiency) .Guiyang ,south of Guizhou ,Bijie were the type of ME-ME (Middle emission-Middle efficiency) .
