| 摘 要： | 研究吉兰泰地区退化梭梭蒸腾生态生理。结果表明，随着光强的增加，退化梭梭蒸腾速率以乘幂的形式增加，且优于生长良好的梭梭（对照）。相对湿度增大，退化梭梭蒸腾速度的减小要比对照快。退化梭梭的蒸腾速度随着温度的增加以乘幂的形式增加。主成分分析结果表明，对退化梭梭蒸腾速率影响最大的生境因子为含水含盐量因子。 |

| Abstract: | On the basis of studying on transpiration Eco physiological characteristics of degenerated Haloxylon ammodendron ,the paper point out:with the increasing of light density the transpiration rate of degenerated H.ammodendron increases in the form of power more quickly than that of the control; With the increasing of relative humidity the transpiration rate of degenerated H.ammodendron decreases more quickly than control's.The transpiration rate of degenerated H.ammodendron increases in the form of power when the temperature increases.The result of principal component analysis is that the factor affect transpiration rate of degenerated H.ammodendron mostly is water salt content. |
| Keywords: | Haloxylon ammodendron Transpiration Eco physiology |
