摘　　要：本项研究工作在测定天然星星草和人工种植生长一至三年星星草光合蒸腾特性季节变化的同时，测定了日照量、气温、地温、相对湿度、降雨量和蒸发量等气候因子的季节变化，并采用相关系数和通径系数分析方法分析了星星草光合蒸腾特性季节变化与这些气候因子的关系。分析的几项气候因子对星星草光合蒸腾特性（光合速率、蒸腾速率、水分利用效率）季节变化的直接作用都是地温最强。The seasonal changes of photosynthesis and transpiration of both natural and planted one to three years Puccinellia tenuiflora , climate factors such as sun quantity, air temperature, earth temperature, relative humidity, rainfall and evaporation are measured. The relationships between seasonal changes of photosynthesis and transpiration of P. tenuiflora and the climate factors are analysed by correlation coefficient and path coefficient analysis. The earth temperature in the analysed climate factors directorly affects the seasonal changes of the photosynthesis and transpiration characters such as photosynthesis rate, transpiration rate and water use efficiency of P. tenuiflora most.
