摘    要:基于“八五”期间长江中上游流域各省的森林资源调查资料,结合经典的材积源生物量法估算了长江中上游防护林体系生物量碳密度和碳贮量,并根据不同树种生物量-生产力回归关系推算了该地区当前的固碳潜力。结果表明:长江中上游地区森林平均碳密度为2575 t/hm2;碳贮量为1 39459 Tg (1 Tg = 1012 g),其中林分(包括经济林)碳贮量为1 20430 Tg,灌木林为13437 Tg,竹林为5592 Tg,三者分别占总碳贮量的8636%、963%和401%。整个防护林体系森林植被的固碳潜力为36856 Tg/a。位于本区西部的四川盆地嘉陵江流域和西部高山峡谷区,其森林碳密度、碳贮量和固碳潜力较高,而东部地区的川鄂山地长江干流、鄱阳湖水系以及洞庭湖水系相对较低,因此,长江中上游森林碳密度、碳贮量和固碳潜力总体上呈现自西向东逐渐降低的趋势。

关 键 词:碳密度  碳贮量  固碳潜力  长江中上游防护林

Abstract:Based on inventory data investigated during the "Eighth Five Year",forest biomass carbon density and storage were estimated by a classical method converting timber volume to total forest biomass.Also,potential carbon sequestration was estimated according to the regressions between forest biomass and net production of different tree species.Average carbon density and total carbon storage in upper and middle reaches of the Yangtze River is 25.75 t/hm2 and 1 394.59 Tg(1 Tg = 1 012 g),respectively.Carbon storag...
Keywords:carbon density  carbon storage  potential carbon sequestration  upper and middle reaches of the Yangtze River
