锡林河流域滨河带湿地植物功能性状及差异研究
Study on the functional traits and differences of wetland plants in Xilin River Basin
摘要
Abstract
The riparian zone,as an interface or an ecological transition zone between the river water system and adjacent land,is an important part of the river landscape.Wetland plants and their communities play an important role in maintaining stability and function of wetland ecosystems.In this paper,20 functional traits of wetland plants in the upper,middle and lower reaches of the Xilin River basin and under grazing disturbance were compared to explore the response of plant functional traits to environment and grazing intensity on the basin scale.The results showed that the variation range of functional traits of wetland plants in different reaches of Xilin River was large,the minimum coefficient of variation in leaf carbon content was 0.05 and the largest coefficient of variation was the photosynthetic rate with a value of 2.64.The structural traits and physiological traits of wetland plants could be adapted to the environment through complementation and substitution,and functional balance changes.The plant height of Mesic herb,Mesophilous herb and Xerophilous herb was significantly lower than that in the slightly degraded plot.The plant height and leaf LCC/LNC(leaf carbon concentration/leaf nitrogen concentration)and LNC/LPC(leaf nitrogen concentration/leaf phosphorus concentration)were significantly different among the five common plant species:Phragmites australis,Blysmus rufus,Potentilla anserina,Agrostis alba,Odontites vulgaris.Under different grazing gradients in the Xilin River basin,the response of plant functional traits to different degradation levels was not consistent,either at the functional group level or at the plant common species level.关键词
