摘要

臺灣杉、杉木及柳杉人工林與天然闊葉樹林，及一個整地後的造林地的輻射能收支量測結果顯示，淨輻射與全天日輻射之比率分別為0.60，0.66，0.67，0.67及0.48。反射率則造林地、臺灣杉人工林、天然闊葉林及杉木人工林依序為15.8%、12.8%、10.8%及10.1%。上述的數值就人工林而言以臺灣杉較低，而杉木與柳杉之間並無差異。淨輻射與全天日輻射比率及反射率在造林地與鬱閉之森林間差異相當大。

Results of radiant flux measurements aver five different vegetation covers indicated that the ratio of not radiation to the global solar radiation were 0.48, 0.60, 0.66, 0.67 and 0.67 for the cleared site, Taiwania cryptomerioides plantation, Cunninghamia lanceolata plantation, Cryptomeria japonica plantation and the lowland hardwood forest, respectively. The albedo for the Canning- hernia lanceolataplantation, lowland hardwood forest, Taiwania cryptomerioides plantation and the cleared site were 10.1%、10.8%、12.8% and 15.8%, respectively. The above values were calculated based on daily total irradiance measurements and can be used for heel budget estimations aver those forest covers in Taiwan.
