中国东北落叶松人工林的CO2通量（英文版）

森林CO2通量的研究已经成为科研的热点而北半球遍布的落叶松林是理想的研究材料之一。我国东北分布的兴安落叶松林(Larixgmelinii)是全球落叶松林的重要组成部分，其在全球变暖进行中的功能尚需阐明。本书是对东北林业大学帽儿山实验林场老山实验站兴安落叶松人工林连续4年（2001-2004）测定结果的综合概论。长期测定的指标包括：落叶松冠层异型枝和林下草本及灌木的碳固定功能、叶片呼吸、树干呼吸、树枝呼吸、球果CO2交换特性及土壤不同组分（土壤微生物、枯枝落叶和根系）呼吸特征并对落叶松、白桦、水曲柳、红松和樟子松的树干呼吸和土壤呼吸种间差异进行了重点分析。进而结合落叶松林的生物量生产力数据和涡度协方差法CO2通量计算结果对落叶松人工林的CO2汇进行了定量估计。本书包括11章，系统阐述了通过测定室生理生态学测定法、生物量累计法和涡度协方法进行林分碳汇估计的原理和方法，对其他森林生态系统碳平衡研究具有借鉴作用。本书可供森林生态学、树木生理生态学和全球变化研究领域的科研、教学和研究生参考。 

Forest Co2 flux has become a hot issue and larch forest ecosystems in the northern hemisphere are very suitable for this study。Larch（Larix gmelinii）forests broadly distributed in Northeast China are important parts of global larch rofests。Their runction in the global warning process needs to be elucidated。This book is a conspectus of four years（2001-2004）study of a larch plantation at Laoshan station，Experimental Forestry Farm of Northeast Forestry University。Functions of dominant canopy heterogeneous shoots and understory shrubs and grasses，respiratory CO2 efflux form elaves，stem，branch，come and different elements of soil（soil microbes，litters and roots） were measured in a long-term monitoring and the inter-species diffe=erence of soil and stem respiration between larch and accompanying species of birchm，mandshurica ashm，Korean pine and Scots pine were also emphasized。On this data base，larch biomass and productivity as well as gas exchange data from eddy covariance method were analyzed to estimate the carbon sink capacity of the larch plantation。11 chapters are included in this book。It will be a reference ofr studying carbon balance of forest ecosystems by methods of gas exchanges，biomass summation and tower monitoring by eddy covariance method。Researchers and graduates focusing on forest ecology，tree ecophysiology and global warming well be the audience of this book。
