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。
Taking the 18-year-old Eupatorium fortunei plantation as the research object, the growth conditions under the same site conditions of soil, geology, landform, climate and moisture were studied emphatically. The distribution of leaf function, the amount of chlorophyll , Leaf nutrient content and other aspects were discussed. The results show that different light energy distribution and absorption make the morphology of Picea koraiensis different, which is one of the important factors affecting the productivity of Picea koraiensis plantation.
