摘 要:土壤/植被碳储量及其空间分布在全球气候变化中起着重要作用。介绍了碳储量估算方法主要有土壤类型法、生命地带类型法、模型法等,指出由于研究尺度和数据来源不同,森林土壤/植被的碳密度和碳储量统计结果尚存在很大的不确定性。进而分析和比较了区域、国家和全球尺度森林土壤/植被碳储量及其空间分布特征,最后提出采用实时动态监测(RS/GIS)与长期定位实验实测数据相结合方法估算土壤/植被的碳密度/碳储量是提高森林土壤/植被碳储量估算精度的重要措施。Soil/Vegetation carbon storage and its spatial distribution characteristics play an important role in global climate change .Estimation methods of carbon storage mainly included soil type method, life zone type method, model method and so on.It was pointed out that the statis-tical results of carbon density and carbon storage in forest soil/vegetation still were great uncertainty due to the different research scales and da-ta sources.Then, we analyzed and compared the regional, national and global scale forest soil/vegetation carbon and its spatial distribution characteristics.Finally, real-time dynamic monitoring (RS/GIS) combining with a long-term experiment measured data was used to estimate the carbon density/storage of soil/vegetation, which was an important measure to improve the estimation precision of forest soil/vegetation car-bon storage reserves.
