| 摘 要： | 以长白落叶松人工林为对象,研究不同配置对太阳光能的利用率,结果表明:矩形配置对太阳能的利用率最高,正方形次之,三角形最低。当矩形配置的行距为2.0~8.0 m、株距为1.0 m时,林分年生长量为17.427 5~18.750 8 m3·hm-2,分别比正方形配置和三角形配置增加1.292 7~1.913 2 m3·hm-2和0.379 5~2.616 0 m3·hm-2。矩形配置可显著提高落叶松林地的生产力。

| Abstract: | Larix olgensis Henry was taken as objects to reseach utilization ration of solar energy of different configuration , the results indicated that rectangular configuration had the highest utilization ration of solar energy , square took the second place, and triangle was the lowest .When array pitch of ectangular configuration was 2.0 ~8.0 m, plant spacing was 1.0 m, annual growth of forest stand was 17.427 5~18.750 8 m3 · hm-2 , which was 1.292 7~1.913 2 m3 · hm-2 and 0.379 5~2.616 0 m3· hm-2 more than square configuration and triangle configuration , respectively.Rectangular configu-ration could significantly increase the productivity of Larix olgensis Henry. |
