| 摘 要： | 采用多元回归分析和灰色关联分析方法,探讨下蜀次生栎林蒸腾强度与生态因子的相关关系。研究认为用二次工咕次多项式回归方程和指数回归方程拟合更能反映各生态因子在整个生长季中与蒸腾强度关系的性质。影响蒸腾强度的主要生态因子是温度和净辐射;其次是空气相对湿度和土壤热流通量;风速和土壤含水率的影响很小。灰色关联分析与多元回归分析的结论一致。研究结果为进一步阐明次生栎林的结构和功能提供了理论基础。

| Abstract: | The correlation between environmental factors and transpiration intensity of the secondary oak stand was studied. The correlation of the transpiration intensity and environmental factors simulated by second or third multinomial regression equations was perfect than by one variable linear regression equation and exponential regression equation. The results showed that the major environmental factors affecting transpiration intensity were net radiation and air temperature. Relative humidity and soil heat fluxes came in second. Wind velocity and average water capacity of soil were unremarkable. |
