摘　　要：【目的】引种、筛选适合在湖南省推广种植的草本地被植物,为湖南省解决绿化建设中草本地被植物种类单一问题提供参考依据。【方法】根据湖南省气候特点及草本地被植物应具备的功能,参照前人的成果和专家意见,对引种的瞿麦、紫娇花、绿苋草、血草、柳叶马鞭草、金叶苔草等6种地被植物生长状况、观赏价值、抗逆性3个方面的14个指标设置相应权重,从优到劣进行5级描述,采用5分制计分法标记,获得评判标准并对引种的6种地被植物进行综合评选。【结果】自然高度最低和扩展能力最强的是金叶苔草;观赏效果最好的是瞿麦;抗逆性最强的是绿苋草;6种引种的地被植物综合指标加权后总分从高到低依次是:金叶苔草>绿苋草>紫娇花>瞿麦>血草>柳叶马鞭草。【结论】金叶苔草、绿苋草和瞿麦适合在不易积水的绿地推广种植,紫娇花适宜在滨水绿地推广种植。【Objective】The herbaceous ground cover plants suitable for extension in Hunan province were introduced and screened to provide references for diversifying herbaceous ground cover plants in Hunan greening construction. 【Method】According to Hunan climate properties and the functions of herbaceous ground cover plants, previous research results and experts’ opinions were consulted, and then 14 items relative to plant growth situation, ornamental value and stress resistance of 6 species of ground cover plants introduced to Hunan were put into the corresponding weight through the description of 5 ranks from good to bad and 5 score system was set to obtain assessed criterion and comprehensively evaluate the 6 kinds of new introduced plants. 【Result】The plant height of Carex ‘Evergold’ was the shortest but its spread ability was the strongest. The ornamental effect of Dianthus Superbus was the best. The resistance ability of Altemanthera Paronychioides was the strongest. The order of comprehensive weighted score of 14 indexes for 6 species of introduced ground cover plants was Carex ‘Evergold’〉Altemanthera Paronychioides〉Tulbaghia violacea〉Dianthus Superbus〉Imperata cylindrical ‘Rubra’〉Verbena bonariensis. 【Conclusion】Carex ‘Evergold’, Altemanthera Paronychioides and Dianthus Superbus are suitable to extend in the green area of highland, but Tulbaghia Violacea is proper to extend in the green area of waterfront in Hunan.
