【摘要】 基于多源遥感影像,从景观格局和空间耦合的角度对塔里木盆地景观格局演变进行分析,并结合当地碳收支状况,分析景观格局演变对碳收支的影响。结果表明:(1)在气候变化和人类活动影响下,塔里木盆地植被状况有变好趋势,有林地、耕地面积明显增加,草地面积略微增加;(2)塔里木盆地碳收支状况良好,呈现碳汇状态,且碳汇能力逐渐增强;(3)以防沙固碳和输水导水为目的的人类活动改善了塔里木盆地生态环境,在气候变化背景下应进一步加大治理力度。更多还原

【Abstract】 By considering the coupling of landscape patterns and space,the evolution of landscape patterns in Tarim Basin was studied through analyzing multi-source remote sensing images. The influence of landscape pattern on carbon budget was also investigated in this study. The results show that:(1)The vegetation condition in Tarim Basin becomes better due to the positive influence of climate change and human activities. The woodland area and the cultivated area both significantly increased while the grassland area slightly increased;(2)The carbon budget in Tarim Basin is in good condition with carbon sequestration. Its capacity gradually increased from 2001 to 2010;(3)Although current human activities including sand prevention and carbon fixation,water delivery,and water conductivity improved the ecological environment in Tarim Basin,further ecological management should be carried out considering climate change impacts.更多还原
