安徽省土地利用/覆被变化的碳排放效应分析

Analysis of Carbon Emissions due to the Land Use/Cover Change in Anhui Province

在前人研究成果的基础上,运用碳排放估算模型,计算安徽省在21世纪前10年里土地利用/覆被变化的碳排放效应。结果表明,研究区陆地生态系统整体上表现出碳汇效应,2000、2005、2010年净碳汇总量分别为13 116万、15 138万、11 559万t;林地为最大碳汇,建设用地为主要碳源;植树造林背景下区域碳汇功能显著提升并维持稳定,表现为能源消费碳排放形式的建设用地碳排放量与日俱增。

Based on previous research results,using carbon emission estimation model,the land use / cover change carbon emission effect in first 10 years of 21 st century in Anhui Province was calculated. The results showed that the amount of carbon sequestration in 2000,2005,2010 is 1311. 6,1513. 8,1155. 9 billion ton. Woodland is the largest carbon sink,construction land is the main carbon source. Regional carbon sink function significantly improved and remained stable carbon,but emissions from construction land was increasing.
