摘　　要：摸清植被碳含量本底信息是估算金沙江上游植被碳储量的基础。结合实地调查和文献分析,对比分析金沙江上游的主要植被类型碳含量与其他流域的差异,并对差异性原因进行了探讨。结果表明:同一树种碳含量在不同流域地区之间存在一定差异,金沙江上游除马尾松外,其他树种的碳含量普遍高于其他地区。金沙江上游地区独特的海拔、气温、光照、降水、土壤条件、地形地貌、人类活动、生态系统等多重因素对金沙江上游地区植被碳含量有着非常重要的影响。研究成果可为金沙江上游植被碳储量估算、固碳增汇优势物种选择提供参考。Understanding the background information of vegetation carbon content is the basis for estimating the vegetation carbon storage in the upper Jinsha River.Based on field surveys and literature analysis,we compare the differences of carbon content in major vegetation types between the upper Jinsha River and other watersheds,and explore the reasons for the differences.The results indicate that the carbon content of the same tree species varies among different watershed areas.In the upper Jinsha River,the carbon content of most tree species,except for Masson pine,is generally higher than that in other areas.Multiple factors,including the altitude,temperature,sunlight,precipitation,soil conditions,topography,human activities,and ecosystems in the upper Jinsha River,play a significant role in influencing the carbon content of the region's vegetation.The research findings can provide references for estimating the vegetation carbon storage and selecting the advantageous species for carbon sequestration enhancement in the upper Jinsha River.
