[目的]为衡阳盆地紫色土丘陵坡地的植被恢复提供参考.[方法]对柏木、芦竹、马桑、刺槐、草木樨与龙须草等6种植物采取盆栽控水方式进行了水分胁迫,测定各植物的抗旱性主要生理指标,并采用隶属函数法对6种植物进行综合评定.[结果]叶片相对水分亏缺、保水力、脯氨酸含量、可溶性糖含量、丙二醛含量、相对导电率、叶绿素含量等是影响植物抗旱性的主要生理指标;6种植物的抗旱性强弱顺序为马桑>柏木>刺槐>芦竹>草木樨>龙须草.[结论]该研究结果对衡阳盆地紫色土丘陵坡地的植被恢复与重建有着重大意义.
[目的]為衡暘盆地紫色土丘陵坡地的植被恢複提供參攷.[方法]對柏木、蘆竹、馬桑、刺槐、草木樨與龍鬚草等6種植物採取盆栽控水方式進行瞭水分脅迫,測定各植物的抗旱性主要生理指標,併採用隸屬函數法對6種植物進行綜閤評定.[結果]葉片相對水分虧缺、保水力、脯氨痠含量、可溶性糖含量、丙二醛含量、相對導電率、葉綠素含量等是影響植物抗旱性的主要生理指標;6種植物的抗旱性彊弱順序為馬桑>柏木>刺槐>蘆竹>草木樨>龍鬚草.[結論]該研究結果對衡暘盆地紫色土丘陵坡地的植被恢複與重建有著重大意義.

[Objective] The reference for the vegetation restoration in purple soil of hilly slope in Hengyang Basin was provided.[Method] The experiment in the potted cultivation of six species of cypress(Cupressus chengiana S.Y.Hu),gaintreed(Arundo donax Linn),coriaria (Coriarianepalensis),black locust(Robinia psendoacacial),sweet clover(Melilotus suaveolens) and Eulaliopsis bina (Retz) C.E Hubbard under water stress was conducted and main physiological indicator of the plants to drought resistance was measured and the tested resulrs were comprehensively evaluated with function method.[Results] The physiological indicators,which affected the resistance of plant to drought,including the relative shortage of water,the capacity in water retention,the content of proline,soluble sugar and MDA,the relative conductivity,the content of chlorophyll and others, in leaf of six species of plants were analyzed and the order of the drought resistance of these plants from strong to weak was order of coriaria >cypress >black locust >gaintreed >sweet clover >Eulaliopsis bina (Retz) C.E Hubbard.[Conclusion] It was of great significance in the vegetation restoration and reconstruction in the purple soil of hilly slope in Hengyang Basin.
