摘要:
测定和分析了2005年8-10月份、2006年4-7月份秦岭火地塘林区油松林太阳辐射的变化，并通过归类对晴天、阴天辐射平衡分量以及反射率、净辐射率、有效辐射率的日变化特征进行分析。结果表明油松林日平均总辐射、净辐射、反射辐射和有效辐射分别为14.83、9.13、1.29、5.83 MJ·m-2；晴天，总辐射、净辐射、反射辐射日变化呈单峰曲线变化，阴天呈多峰曲线；油松林林冠有效辐射始终为正值；不同天气条件下反射率、有效辐射率呈“U”形变化；净辐射率变化趋势为白天高，早晨、傍晚低，晴天净辐射率为63.58%-65.08%，阴天净辐射率为56.36%-71.60%。
Abstract:
Daily values of solar radiation components of Pinus tabulaeformis community in Huoditang Forest Farmin Qinling Mountains from year 2005（August to October）to year 2006（April to July）were measured and analyzed. Daily variations of radiation balance components , distributing ratios of reflective radiation, net radiation and effective radiation in sunny days and in cloudy days were analyzed .The main conclusions were as follows. Average values of daily global radiation ,net radiation, reflective radiation and effective radiation received by Pinus tabulaeformis community were 14.83,9.13,1.29,5.83 MJ·m-2 respectively. In sunny days, daily variations of global radiation, net radiation and reflective radiation presented an onepeaked pattern, while solar radiation components showed a pattern of several peaks in cloudy days. Effective radiation received by Pinus tabulaeformis community above the canopy was positive. In sunny days and cloudy days, daily variations of distributing ratio of reflective radiation and effective radiation presented a “U” pattern. Daily variations of distributing ratio of net radiation showed a tendency of higher values at daytime and lower in the early morning and in the afternoon. In the daytime, the scopes of variation of distributing ratio of net radiation in sunny days and in cloudy days were 63.58%-65.08% and 56.36%-71.60% respectively.
