| 摘 要： | 对长白松人工林生态系统营养元素的分配格局和积累规律研究表明，乔木层不同器官营养元素含量为叶＞枝＞根＞干皮＞干材；同化器官──针叶中养分含量为Ｎ＞Ｋ＞Ｃａ＞Ｐ＞Ｍｇ；吸收器官──根中养分含量为Ｃａ＞Ｎ＞Ｋ＞Ｐ＞Ｍｇ；人工林生态系统中的养分含量为土壤＞凋落层＞草本层＞灌木层＞乔木层，乔木层养分贮量和积累率分别为８８．７９％和７６．４３％；长白松林生态系统中植物对Ｎ、Ｐ的吸收较强烈．

| Abstract: | The study shows that in tree layer,the nutrient content in various organs is in the order of needle>branch>root>bark>trunk,that in assimilated organ is in the order of N>K>Ca>P>Mg,and that in absorption organ is in the order of Ca>N>K>P>Mg In plantation ecosystem,the nutrient content is in the order of Soil>litter>herb layer>shrub layer>tree layer.The nutrient storage and its accumulation rate in tree layer are occupied by 88.79 % and 76.43% respectively.The absorption of N and P by plants in Pinus sylvestriformis ecosystem is more intensive. |
