摘要
为了掌握退化草原补播前后植物群落物种多样性的变化情况,以平罗县天然草原为研究对象,先用机械条播的方式对退化的草原进行补播,然后对比补播前后植物种类、高度、盖度、密度、地上生物量等的变化.结果表明:补播可以提升物种多样性、物种丰富度,植物生活型,但草原植被盖度、密度及地上生物量均呈下降趋势.
Abstract
In order to understand the changes of the species diversity of plant communities on degenerated grassland reseeding in Pingluo,mechanical seeding was used to reseeding degenerated grassland in this study.The changes of the species,height,coverage,density and aboveground biomass of plants were monitored.Monitoring results show that the reseeding could improve species diver-sity,species richness,plant life type,but it reduced vegetation coverage,density and aboveground biomass.
