摘要

本研究蒐集溪頭氣象站、溪頭柳杉林微氣象站與溪頭崩塌地試驗區氣象站自2005年1月起至2007年12月止之觀測資料，應用綜合法分析顯熱通量、潛熱通量兩種分量，另以梯度法分析土壤熱通量。結果顯示，復育區地表已逐漸形成植被覆蓋，因此並未產生新崩塌現象。由於復育之植物冠層趨於鬱閉，太陽輻射被攔截、吸收與反射，致使抵達地表之太陽輻射呈現直線下降趨勢。復育區站經幾年來植被穩定成長，地表之熱量收支已介於草類與森林之間。

The purpose of this study was to analyze the sensible and latent heat fluxes of Agro-Observatory, Micro-Observatory and Regeneration Observatory by Bulk method with the data collected during the period from January 2005 to December 2007 at Sitou region of the central Taiwan. In addition, soil heat flux was analyzed by Gradient method. Results of the heat budget analysis showed that the site deteriorated by landslide disaster was regenerated gradually by vegetation without further landslide. The incident solar radiation at the soil surface was decreased linearly due to the canopy closure that intercept, absorb and reflect the incoming radiation. The heat budget of surface layer at regeneration site was in between meadow and forest caused by the steady-growing vegetation.
