黄土丘陵区退耕地先锋群落演替过程中细根特征的变化
-
The results show that , in natural forests , structural diversity of pioneer community is much lower than that of late successive community ;
不同群落的结构多样性计算结果表明，处于演替后期的辽东栎天然林比演替初期的白桦林有较高的结构多样性；
-
The range of indexes of succession is from 4.12 to 7.86 . As the evergreen broad-leaf forest is the climax phase , the coniferous and broad leaf forest has already taken the place of pioneer community .
母树群落演替指数在4.12至7.86之间，已经完成针叶林先锋群落马尾松群落向针阔混交林的过渡，并将最终演替到顶极常绿阔叶林。
