摘　　要：全球气候变化是当前人类生存和发展所面临的严峻挑战,森林生态系统在减缓温室效应和维持全球碳平衡中发挥着重要作用。本文以黑龙江省小兴安岭地区森林为研究对象,将通量观测和生态过程模型相结合,采用Biome-BGC模型估算森林碳通量,使用M-K方法和EOF方法进行了时空分析,并发现了2000—2015年小兴安岭森林碳通量的时空特征规律。研究结果表明:在时间上,具有明显的年际变化特征,且呈波动下降的总趋势;在空间上,具有同向分布模式和反向分布模式的空间分布特征。本研究成果将为我国制定应对全球变化的战略决策,以及生态文明建设和环境保护提供科学参考依据。Global climate change is a severe challenge for human survival and development.Forest ecosystem plays an important role in reducing greenhouse effect and maintaining global carbon balance.In this paper,the forest in Xiaoxing′anling of Heilongjiang province was taken as the research object.The biomass BGC model was used to estimate the forest carbon flux by combining flux observation and ecological process model.The M-K method and EOF method were used to analyze the spatio-temporal characteristics of forest carbon flux in Xiaoxing′anling from 2000 to 2015.The results show that:in terms of time,it has obvious characteristics of inter-annual variation,and shows a general trend of fluctuation decline;In space,it has the same direction distribution pattern and reverse distribution pattern.The results of this study will provide scientific reference for China to make strategic decisions to deal with global change,as well as ecological civilization construction and environmental protection.
