| 摘 要： | 较系统地研究了鼎湖山马尾松林营养元素的分布和生物循环情况。马尾松林内各组分营养元素浓度总的规律为：针叶－细根－林下层植物－凋落物－树皮－树干；在树皮，树干和凋落物组分中各营养元素的排序为：Ｎ－Ｃａ－Ｋ－Ｍｇ－Ｐ，其它组分中则为：Ｎ－Ｋ－Ｃａ－Ｐ－Ｍｇ。马尾松林各营养元素的总贮量（ｋｇ／ｈｍ＾２）为：２２７８．５１（Ｎ＊），２８０．０１（Ｐ），５６７．９０（Ｋ），４５６．８４（Ｃａ），１４４．７６（

| Abstract: | Nutrient distribution and cycling of a Masson's pine ( Pinus massoniana ) planted forest in Dinghushan,Guangdong Province were systematically studied.Nutrient concentrations of various components showed the following order:needles>fine roots>understory>litter>bark>wood.The nutrient element patterns were:N>Ca>K>Mg>P in bark,wood and litter components,and N>K>Ca>P>Mg in other components.The total nutrient standing stocks were estimated to be (kg/hm 2):2278.51(N), 280.01 (P),567.90(K),456.84(Ca),and 144.7... |
