摘　　要：为探究娄底市草坪杂草种类、分布及危害状况,通过野外调查、查阅植物标本信息和文献资料,应用统计方法分析重要值等指标,确定娄底市草坪常见杂草有68种,隶属28科58属,以菊科、禾本科、伞形科为优势科;一年蓬(Erigeron annuus)、看麦娘(Alopecurus aequalis)、白茅(Imperata cylindrica)等13种杂草为杂草优势种,应列为主要防控对象。本研究为娄底市草坪杂草的防控与综合利用提供了重要资料,也可为其他地区杂草的类似研究参考。The distribution and harmfulness of turf weed species in Loudi City were investigated, and statistical methods were applied to analyze the importance value and other indices. Sixty eight turf weed species in Loudi City were identified based on field surveys, information from herbariums,and literature reviews. They belonged to 58 genera of 28 families, in which Compositae,Gramineae, and Apiaceae were the dominant families. The 13 dominant species included Erigeron annuus, Alopecurus aequalis, and Imperata cylindrica, which should be the target weeds for control. This research provides some important data for the prevention, control, and comprehensive utilization of the turf weeds in Loudi City, and a reference for similar studies in other parts of the world.
