　　研究卧茎景天在岩石边坡应用的适应性。在沈吉高速清源段裸露的岩石边坡栽植卧茎景天，测定卧茎景天在干旱胁迫下的生理指标变化、试验段卧茎景天地上部与地下部生物量，以及植物群落调查情况。试验表明，通过3种基本的逆境生理指标显示，卧茎景天有较好的抗旱性，同时在生态适应性方面，地上和地下生物量比例达到12.15，SDR值达到50.32，能适应岩石边坡恶劣条件。卧茎景天可以在岩石边坡应用。

The adaptability of Sedum lineare Thunb on the stone slope was studied in this article. Sedum lineare Thunb was planted on bare stone slope of the Qingyuan part of the Shen?ji highway. The physiological indicators under drought stress, above-ground and underground biomass were determined, and the plant communities were investigated. The results showed that Sedum lineare Thunb expressed strong drought resistance through the three basic adversity physiological indicators. In aspects of ecological adaptability, the proportion of above-ground and underground biomass reached 12.15, and the value of SDR reached 50.32. So it is able to adapt to harsh conditions. Sedum lineare Thunb could be applied on the stone slope.
