摘要
利用第三次森林清查(1984-1988年)中宝兴县数据,结合2005年TM遥感影像土地利用类型图土壤类型图,采用植被类型碳密度以及土壤碳密度经验值的方法,估算了宝兴县碳库以及自然生态系统碳汇。并收集宝兴能源消耗、土地利用变更、替代能源工程等人为因素的数据估算了宝兴县2005年的人为碳排放及碳减排放效应,从而计算出宝兴县总碳增汇效应,碳汇为452.80×106kg C,并分区定量、图形表示,为地方政府提供决策支持。
Based on the 3rd National Continuous Forest Surveying Database from 1984 to 1988,couple with land use data and soil type data supporting by Landsat TM in 2005,carbon storage and carbon sequestration in Baoxing County,Sichuan Province were estimated by statistical method.Carbon emission and carbon emission reduction were estimated by collecting data of energy consumptions,changes in land use,alternative energy source and other human factor.Total carbon absorption was 452.80 ×106 kg C existed in Baoxing County in 2005,and partition quantity and graphical representation of carbon absorption,carbon emission were also performed,which would be helpful for local government decision.
