摘　　要：基于7点均匀设计用Li-6400光合测定系统对成年鹅掌藤(Schefflera arboricola Hay.)在不同光照强度、温度、湿度因子组合下的光合速率进行了模拟测试。对测试结果进行了多元一次、多元二次回归对比分析,得出了对于园林植物鹅掌藤多元二次回归方程对光照强度、温度、湿度多因子组合下的光合速率性状描述效果最好。结果表明:在深圳冬季影响鹅掌藤光合速率的主要因子是光照强度,光照强度与光合速率呈二次方程曲线相关。The photosynthetic rate of Schefflera arboricola Hay.had been observed by means of Li-6400 Photosynthesis Analyzer to explore the influence of multiple factors(light intensity,temperature and humidity)upon the mature leaf based?on?Uniform Design.The comparative analysis between Linear Regression,multivariate quadratic regression indicated thatmultivariate quadratic regression was better than the others.The results indicated that light intensity is the primary factor that may affect photosynthetic rate of Schefflera arboricola Hay.in winter.There was a?positive correlation?between the light intensity and the photosynthetic rate.A r2negative correlation?was found between the light intensity and the photosynthetic rate.
