| 中文摘要 | 在複雜的物理環境因子中,太陽輻射為生態系之主要能量來源,為生態環境研究上之有效變數,亦為整體生態系能量、養分循環及食物鏈關係之影響機制,因此如何掌握空間性太陽輻射能的變化為生態系能量等研究的重點。本研究以PSP校正自製儀器後,再於麟趾山及和社溪溪谷利用自製儀器進行現地觀測,進行散射輻射及地表反射輻射之模式驗證。結果顯示,均向性假設下,再利用全天光空域比例因子進行散射輻射量估算,以及修正Dozier模式所估算之周遭地形反射輻射量估算,於森林地區之應用上有其可行性。 |
| 英文摘要 | Among the intricate network of physical environmental factors, solar radiation constitutes the main source of energy for all ecological systems. It is not only the effective variant in ecological and environmental studies, but also the influencing mechanism behind the entire ecosystem energy, nutrient cycles and food chains. As such, the control of the spatial variation of solar radiation thus becomes the focus of most ecosystem studies. This study used the precision Spectral Pyranometer (PSP) to calibrate our self-designed devices. Then, these self-designed devices were observed at Mount Ling-jih and He-she river valley to validate the skylight radiation model and the terrestrial reflected radiation model. Results showed that under the hypothesis of isotropy, the estimation of skylight radiation through skyview factor, and the estimation of terrestrial reflected radiation based on the modified Dozier model are both applicable to forest areas. |
