摘要
本文用ZHT型数字式蒸腾仪对蒙古栎群落及其种群,进行了连续的时间及空间梯度测定与分析,得出了蒙古栎群落乔木、灌木及草本植物蒸腾强度的日变化规律,并从蒸腾生理角度提出了各种群在群落中的地位,说明了蒸腾强度是反映种群空间分布格局的一个生理指标。
This paper deals with the measurement and analysis on the continuous time gradients and spatial gradients of oak community and its poapultionswith ZHT potet?meter. The daily variation laws of transpiration intensityof tree、shrub and herb layer are obtained. The status of each populationin the community is suggested at the tranpiration physiology angle. Thetranspiration intensity is a physiological factor that can reflect the spatialpattern of population.
