THE DIURNAL CHANGE IN THE PHOTOSYNTHETICRATE OF LEYMUS CHINENSE GRASSLAND COMMUNITYOF INNER MONGOLIA AND ITS ENVIRONMENTALRELATIONSHIPS
内蒙羊草草原群落光合速率日变化及其与环境条件之间相互关系的初步研究

The properties of the diurnal change in the photosynthetic rate of Leymus chinense grassland community in the typical steppe region of the middle east part of Xilingole League, Inner Mongolia are discussed in this paper.1. There is a reduction in the photosynthetic rate of Leymus chinense grassland community at the noon time with a narrow fluctuation.2. There are close relationships between the diurnal change in the photosynthetic rate and the integrated effects of environmental factors. The limiting factor...
