摘要
以18年生红皮云杉人工林为研究对象，着重考察在土壤、地质、地貌、气候、水分等条件相同，而光照不同的立地条件下的生长状况，并从叶面函数分布、叶绿素合量、叶片中营养元素含量等方面进行了论述．结果表明，不同的光能分布和吸收使红皮云杉的形态产生了差异，光是影响红皮云杉人工林生产量的重要因子之一。
This paper describes mainly artificial forest of 18 years old Picea koraiensis and investigation its growth form, when the soil, geology, landforms, chlimate and water are same, but only light is variab1e, all of them are discussed through ranging of blade function, content of chlorophyll and content of nutrition element in blade. The results show that when ranging and receiving of solar light energy are different, form of Picea koraiensis is different. The solar light is one of important factors affecting growth of artificial forest of the tree.
