摘　　要：为了探究10种野生地被植物的生态效益价值,通过田间引种栽培试验,测定其叶面积指数、滞尘量、日释氧固碳量及日吸热量。结果表明:蓝花棘豆的叶面积指数最大,为6.66;斑叶堇菜的周滞尘量可达到2.41g/m2,滞尘效果明显;鹅绒委陵菜的日释氧固碳量及吸热量均是10种野生地被植物中最大,表现出了优良的生态效益价值。综合以上指标,可以看出鹅绒委陵菜、斑叶堇菜、蓝花棘豆等地被植物具有较高的滞尘、固碳释氧、吸热等生态效益价值。In order to understand the ecological benefits of the 10 plant species of wild ground covers, LAI, dust detaining, the carbon-fixing, oxygen-releasing and absorbing heat quantity were measured in this study. The results showed that the LAI of Oxytropis coerulea was the biggest with 6. 66, the dust detaining of Viola variegata was 2.41g/m2, the carbon-fixing, oxygen-releasing and absorbing heat quantity of PotentiUa anserina were much big- ger than the other 9 species. Based upon these measured indicators, Potentilla anserina, Viola variegata, Oxytropis coerulea have higher ecological benefit than those of other species.
