Quantitative Classification and Ordination of Plant Vegetation in the Bosten Lake Wetlands
-
摘要: 应用双向指示种分析(TWINSPAN)方法对湿地植物群落进行分类,采用除趋势对应分析(DCA)、典范对应分析(CCA)对群落进行排序,以明确博斯腾湖湖滨湿地的主要植物群落类型及影响植被类型变化和分布的主要环境因子。结果表明,博斯腾湖湖滨湿地植被可分为7个主要群丛,分别为长苞香蒲(Ass. Typha angustata)、芦苇+长苞香蒲(Ass. Phragmites australis + Ty. angustata)、芦苇+水烛(Ass. P. australis + Ty. Angustifolia)、多枝柽柳-芦苇(Ass. Tamarix ramosissima-P. australis)、胡杨-多枝柽柳(Ass. Populus euphratica-Ta. ramosissima)、旱柳-多枝柽柳(Ass. Salix matsudana-Ta. ramosissima)和多枝柽柳(Ass. Ta. ramosissima),它们分布于湖滨浅水带、湖滨沼泽带、湖岸乔灌林带和旱生灌丛带;TWINSPAN分类产生的7个主要群丛在DCA排序图上被很好地反映出来。CCA排序与DCA排序结果基本一致,说明土壤含水量和土壤总含盐量是决定该地区植被分布格局的主要环境因子。博斯腾湖湖滨湿地植被种类单一,生态结构简单,水盐动态及其相互作用是影响该地区植被分布的主要因素之一。因此,在对博斯腾湖湖滨湿地进行植被保护与重建过程中,需重点考虑土壤含水量和土壤总含盐量这2个主要环境因子的影响,合理开发、利用水资源,防止土壤盐渍化的发生。Abstract: TWINSPAN, DCA and CCA methods were used to classify plant community types and determine the relationship between vegetation and environmental factors in order to evaluate the influence of environment regulation on vegetation in the Bosten Lake wetlands in Xinjiang. TWINSPAN results showed that the vegetation in this region could be divided into seven associations, which were distributed along the wetland shallow water zone, marsh zone, bush and tree lakeshore zone and xeric shrub zone. These associations were: Ass. Typha angustata, Ass.Phragmites australis+Ty.angustata, Ass.P.australis+Ty.angustifolia, Ass.Tamarix ramosissima-P.australis, Ass.Populus euphratica-Ta.ramosissima, Ass.Salix matsudana-Ta.ramosissima, Ass.Ta. ramosissima. These associations were also well reflected in the DCA ordination graph. The CCA results were basically consistent with the DCA results, and showed that the vegetation distribution patterns correlated with major environmental variables of soil water content and total dissolved solids. The species characteristics and ecological structures of wetland vegetation in the Bosten Lake wetlands were single and simple. Dynamics and interactions of water and salt were the main factors that influenced the distribution of vegetation in the area. This study confirmed that planners and managers of nature reserves in this area should take the two major environmental factors of soil water content and total dissolved solids, and species characteristics into account during decision-making processes.
