Nutrient contents of vegetation and their allocation characteristics in main forests of Guizhou Province

摘要: 通过对贵州9种主要森林类型植被层养分含量(N、P、K)的调查,分析了养分在乔木层、灌木层和草本层中的分配特征。结果表明:林下植被层养分含量均高于乔木层,总体上草本层养分含量最高,灌木层和乔木层因群落不同而异。混交林养分含量高于纯林,天然林高于人工林,速生树种大于慢生树种。各种森林类型植被层中,N、K元素相对P元素含量较多,N含量是P含量的3.0～24.1倍,K含量是P含量的3.6～16.8倍。乔木层不同器官养分含量总体上表现出叶＞皮＞枝＞根＞木材的趋势;灌木层不同器官养分含量基本表现为叶＞根＞枝干;草本层养分含量均表现为地上＞地下。Abstract: Based on the survey on the nutrient contents (N, P, and K) of vegetation in nine major forests of Guizhou, the allocation characteristics of the nutrients in the arbors, shrubs and herbs were analyzed. The results revealed that the nutrient contents in undergrowth vegetations were higher than those in the tree layer, and overall the highest in herb layer. The nutrient contents in shrub layer and tree layer varied among communities. The nutrient contents in mixed forests were higher than those in pure forests, higher in natural forests than in artificial forests, and higher in fast-growing tree species than in slow-growing tree species. In all these forest vegetations, the contents of N and K were more than those of the P with N 3.0--24.1 times and K 3.6--16.8 times as high as P. The allocation of nutrient contents in the tree layers was shown as leaf bark branch root timber, in the shrub layers as leaf root stem, and in the herb layers as aboveground underground.
