摘　　要：调查了桃园草本植物的发生特点及群落组成,通过计算Margalef丰富度指数、辛普森指数、草本植物相对高度、生态位等指标并筛选了适合桃园自然生草的优良草本植物种类。结果表明:桃园草本植物共67种,隶属于24科59个属。春季主要以禾本科、菊科、十字花科草本植物为主;入夏十字花科草本植物逐渐消退,禾本科和菊科草本植物依然占主导位置,直至10月底;8月为桃园全年草本植物丰富度指数最高月份。筛选结果表明:平车前、三齿萼野豌豆、蒲公英、华蒲公英、苦荬菜可作为桃园自然生草的优良草本植物种类。The occurrence status and community composition of herbaceous plants in peach orchard were investigated in this paper.By calculating the Margalef richness index,Simpson index,relative height,niche breadth,and other indicators,the fine herbaceous plant species suitable for natural grass growing in the peach orchards were screened. The results showed that there were 67 species of herbaceous plants in the peach orchard,belonging to 59 genera and 24 families. In spring,the plants were mainly the gramineae,compositae,and cruciferae. In summer,the cruciferae gradually faded away,the gramineae and compositae still dominated until the end of October. August was the month with the highest herb richness index in the peach orchard. The screening results showed that Plantago depressa,Vicia bungei,Taraxacum mongolicum,Taraxacum sinicum,and Ixeris denticulate could be used as excellent herb species for natural grasses in the peach orchard.
