Based on the community investigation and analysis of different abandoned field succession stages from 2, 6, 9, 13, 16, 19 , 25, 30 and 40 years, the results show that the succession series is Artemisia scoparia community→Lespedeza davurica community→Agropyron cristatum community→L.
选择9个弃耕地,对群落内植物种类、盖度、密度和生物量进行调查,分析了黄土丘陵沟壑区弃耕地植被恢复演替与物种多样性变化过程,结果表明:1)在弃耕时间为2,6,9,13,16,19,25,30和40年的群落中,演替序列为:猪毛蒿Artemisiascopari群落→达乌里胡枝子Lespedezadavurica群落→冰草Agropyroncristatum群落→(达乌里胡枝子+铁杆蒿A。
