| 摘 要： | 1996年林木生长季节(5~10月)野外条件下测定了12个树种的P-V曲线水分参数。研究了水分参数的季节变化及与林木抗旱性的关系。提出树种在水分胁迫条件下以水分参数Ψisat和Ψitlp所定义的渗透调节能力。并研究了树种的这种渗透调节能力的季节变化规律及与环境因素的关系。应用数量分析的方法对林木的抗旱性予以综合评价。 |

| Abstract: | The P-V Curve water Parameters(WPs) of 12 trees are measured in field condition during tree growth season in 1996. The pattern of Wps' seasonal changes and trees' drought resistance and relationship between them are studied. We present the definition of osmotic adjustment ability(OAA) of trees using the parameter Ψisat and Ψitlp under water stress. The seasonal change pattern of OAA and the relation to the climate factors are studied. The synthetic evaluation of the trees' drought resistance has been done by using the method of quantitative analysis. Meanwhile the order of trees' drought resistance has also been done. |
| Keywords: | Water parameter Drought resistance Quantitative analysis |
