Woodbuffalo national Park is suitable for ecological studied on carbon dynamics. There are three main forest types. Jack pine forests dominate on the higher terrace with sandy glaciolacustrine deposit. Black spruce stands locate on lower topograpy or around bog site. Trembling aspen is dominant species on the terrrace with fine-grained silty sediments. We settled automatic meteorological data logging system using satelite phone in June 2014. Additional maintenance for whole-year monitoring has been done in September 2015. We can access semi-real time data check on HP of Cryosalon. We made site description on moss/lichen communities along a chronosequence of stand replacement fire. Additional forest census plot for stand reconstruction analysis using tree ring data were measured.伍德布法罗国家公园（Wood Buffalo National Park）适用于碳动态相关的生态学研究。园区内分布有三种主要森林类型：发育砂质冰湖沉积物（sandy glaciolacustrine deposit）的高阶地以北美短叶松（Jack pine）林为优势群落；黑云杉（Black spruce）林分布于低洼地形或沼泽周边区域；细粒粉砂沉积物（fine-grained silty sediments）发育的阶地则以颤杨（Trembling aspen）为优势树种。2014年6月，我们搭建了依托卫星电话的自动气象数据记录系统，并于2015年9月完成了该全年监测系统的维护工作。研究人员可通过Cryosalon的主页（HP，Home Page）查询半实时数据。此外，我们针对由林分更替火烧形成的时间序列样地开展了苔藓与地衣群落的样地描述工作，并布设了森林样地调查样方，用于依托树木年轮（tree ring）数据开展林分重建分析研究。
