| 摘 要： | 在分析林下参气孔导度（Gs）日变化的基础上，通过单因子相关分析初步确定各林下环境因子对Gs的作用性质。采用多元回归的方法，确定光合有效辐射（PAR）、空气温度（Ta）、水汽压亏损（VPD）是影响林下参气孔导度的主要因子，并建立了Gs与环境因子间的回归模型：Gs=4.712PAR×10^-4＋1.559Ta×10^-2-0.002VPD-3.657，（R=0.971^＊＊，F=59.074）。

| Abstract: | Based on the diurnal change of stomatal conductance (Gs) of ginseng under forest, the qualities of the environmental factors to Gs were confirmed with correlation analysis. The interaction among factors was analysed with the method of multiple regression analysis. A conclusion was the main factors impacting on stomatal conductance (Gs) of ginseng under forest were photosynthetically active radiation (PAR), air temperature (Ta) and vapor pressure deficit (VPD). The relationship between stomatal conductance (... |
