| Abstract: | Under the natural conditions,the main water parameters of 30 species plants newly introduced into Jinchang city were determined by using pressure-volume(PV) technique,and the drought resistance indexes of those plants were ranked in an optimum order by the values of drought resistance indexes,ratio between bound water and free water.Futhermore,the leaf water potential,reletive water deficits and bulk elastic modulus(ε) have been analyzed,23 species plants were selected with planting measures. |

| Keywords: | introduced plant pressure-volume technique drought resistance index |
