摘要:
该文以位于我国西北半干旱区的宁夏盐池县为研究对象，研究不同植被保护及恢复措施下植物群落结构及物种多样性。选取4类样地类型：分别为老封育区草地、新封育区草地、退耕地、天然草地。老封育区草地各项植物多样性指数均为4类样地类型中最低，可见，并不是封育年限越长，植被恢复生长效果就越好。退耕地的综合多样性指数及均匀性指数在4类样地类型中均较高，退耕还草是一种非常可取的植被恢复措施。
Abstract:
Yanchi county, located in semiarid region in northwestern China, is taken for representative research example to study the plant community structure and species diversity influenced by different measures of vegetation protection and restoration. Four types of sample-plots were selected, which were old enclosure field, new enclosure field, rehabilitated field, nature grassland. Each index of the old enclosure field is respectively lowest. That is not to say, the longer the field is protected, and the better the vegetation restores and grows. Both integrated diversity indices and evenness indices of rehabilitated field are relatively higher than others. So it means that returning farmland to grassland is really a kind of reasonable measure for vegetation restoration.
