图2 鼎湖山3种不同演替阶段植被的N、P含量。季风林数据时间范围是1992-2005年; 混交林为2001-2006年; 马尾松林为1992-2006年。同一部分具有不同字母的表示差异显著(p < 0.05)。MEBF、MF、PF, 同图1。

Fig. 2 Plant total nitrogen and phosphorus concentrations among three types of forests at different succession stages in Dinghushan. Data source: MEBF, from 1992 to 2005; MF, from 2001 to 2006; PF, from 1992 to 2006. Different letters indicate significant differences at the confidence level of p<0.05 in the same plant parts among the three forests; MEBF, MF, PF, see Fig. 1.
