几个抗旱树种木质部栓塞脆弱性模型的探讨

On Models of Embolism Vulnerability in the Xylem of Some Drought resistance Tree Species

根据５种抗旱树种一年生小枝的水势和导水率数据资料，在模型ｙ＝ａ＋ｘｂ的基础上，对此模型进行改造得模型ｙ＝ａｅｂｘ，并另提出模型ｙ＝ｘ２ａ＋ｂｘ２。从相关指数计算得各树种的最优模型。

Based on the data of water potential and hydraulic conductivity in one year old twigs of five kinds of drought resistance tree species and the original model y=a+xb , an improved model y=a e bx was set up. Moreover, a model y=x 2a+bx 2 was put forward and optimum models for each tree species were drawn by correlation index.
