二氧化碳濃度在不同林分之時間與空間變異(II)

Abstract

本試驗目的在探討森林生態系二氧化碳濃度之空間及時間變化，以及不同林分組成對二氧化碳濃度之影響。試驗區設於惠蓀林場關刀溪長期生態研究區，於天然闊葉林及人工杉木林選擇三個採樣點，每個採樣點分別架置四個採樣高度進行採樣，同時於林外分別架置相同高度之對照點。

To understand spatial and temporal variation of carbon dioxide concentrations between different forests, an experimental site located at Guandaushi Long-Term Ecological Research Site in Nantou had been selected. Three sampling plots were selected in each of natural hardwood and conifer plantation. Four sampling heights (0.5, 4, 12 m and above canopy) of each plot were set in each forest. Outside the forest, the same sampling heights had to be set as control samples.
