摘要

運用渦度相關法（Eddy Covariance method）之理論基礎於屏東設立通量觀測塔，監測平地造林地之二氧化碳通量。經過觀測系統調整，測站整年平均資料獲取率達88%，經品質分析控制後，可感熱通量平均可用資料率為78%；潛熱通量平均可用資料率為59%；CO_2通量平均可用資料率為61%。另由風場特性分析中顯示試驗地具由明顯海陸風特性。初步檢視屏東試驗地年平均CO_2淨生態系統交換量（NEE）為-0.53 ton C／ha／yr，近乎平衡。

Applying the theory of Eddy Covariance method, the flux monitoring tower was established for measuring CO_2 flux of Pingdong reforestation. This facility aims to calculate the capacity of carbon storage and the reduction of CO_2 emission of forestation on the plain. The results have indicated that the annual mean data acquisition ratio of flux system was 88%. Based on the data amount after the data assurance and quality control processes (QA/QC), the useful data ratios of sensible heat flux, latent heat flux and CO_2 flux are 78%, 59% and 61% respectively. The wind character analysis has showed significant pattern of sea/land breezes. The preliminary CO_2 flux result of the reforestation has showed the annual net ecosystem exchange (NEE) is approximately -0.53ton C/ha/yr.
