| 摘要: |
| 采用野外定位试验的研究方法，研究不同石块覆盖条
件下，植物的发芽率、高度、盖度三项指标的生态恢复效果影响。 结果表明：石块覆盖度
为60%时，紫茉莉的发芽率、高度、盖度各项生长指标最高，分别可达85%、95 cm、100%；
石块覆盖度为10%时，波斯菊的发芽率、高度、盖度各项生长指标最高，分别可达65%、95 c
m、95%。不同生境的总体植物长势表现为：主河槽>泛洪区>河漫滩。该研究结果可为河滨带
保墒技术的实际应用提供理论参考。 |

| Abstract: |
| This study was performed to assess the effect of stone mulches plant by the riverside using field experiments. Treatments of different kinds of rock were conducted, and three parameters including germination rate, plant height and coverage were measured to estimate the ecological effect. The results showed that 60% stone coverage resulted in high germination rate, plant height, coverage of Mirabilis jalapa, being 85%, 95 cm, and 100%, respectively. For cosmos, 10% of stones coverage produced high germination rate, height, and plant coverage, being 65%, 95 cm, and 100%, respectively. Generally, plant performance for different habitats exhibited an order of main river channel＞flood basin＞alluvial flat. The results might be of significance for the development of riverside conservation practices. |
