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%；CO2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CO2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 CO2 flux of Pingdong reforestation. This facility aims to calculate the capacity of carbon storage and the reduction of CO2 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 CO2 flux are 78%, 59% and 61% respectively. The wind character analysis has showed significant pattern of sea/land breezes. The preliminary CO2 flux result of the reforestation has showed the annual net ecosystem exchange (NEE) is approximately -0.53ton C/ha/yr.
