| 摘 要： | 根据2008年的观测数据,分析了会同杉木人工林太阳辐射各分量的时间分布特征及不同季节太阳辐射分配率的差异。结果表明:除大气逆辐射(RLd)外,其余3种辐射的年变化大致呈单峰形;太阳总辐射(RSd)及反射辐射(RSu)日变化均呈规则的单峰曲线,而森林生态系统长波辐射(RLu)和RLd则呈波浪形;就全年太阳辐射的分配率而言,净辐射(23.5%)最大,有效辐射(19.0%)次之,反射辐射最小,仅7.5%;不同季节太阳辐射分配率亦有所不同,反射辐射和净辐射均为旱季小于雨季,有效辐射则相反。

| Abstract: | Based on the observational data of radiation flux in 2008,the distribution characteristics,including downwelling shortwave radiation(RSd),upwelling shortwave radiation(RSu),downwelling longwave radiation(RLd) and upwelling longwave radiation(RLu),and the distribution rate of solar radiation in different seasons of the Chinese fir plantations in Huitong were analyzed.The results show that all of the monthly gross radiation flux fluctuated in single apex in a year,except RLd.And the average diurnal processes ... |
