摘  要:
研究了太行山干旱低山丘陵区林草复合系统能量环境特征,结果表明复合系统年太阳总辐射量为49868.65GJ.hm-2.a-1,光合有效辐射为24244.67GJ.hm-2.a-1,复合系统的平均反射率为22.5%,高于单作苹果系统,平均透射率为18.0%,低于单作苹果系统,说明林草复合系统可以截获和利用更多的光能。

摘  要:
Energy environment characters of a silvopastoral system (apple-alfalfa) was studied in the drought hilly regions of Taihang Mountain. The results showed that the annual solar radiation to the system summed up to 49868.65GJ.hm~(-2).a~(-1), photosynthetically active radiation was 24244.67GJ.hm~(-2).a~(-1), the mean reflection rate of the system was 22.5%, which was higher than that of mono-culture orchard and the average transmission of the system was 18.0%, a little lower than that of mono-cultureapple. This indicated that more solar energy can be used in the apple-alfalfa system.
