摘要
【目的】研究新疆伊犁和塔城地区天山樱桃群落的物种组成及其植物区系分布特征,从而为天山樱桃这一珍稀物种的保护及可持续利用提供理论依据。【方法】采用典型样方调查法,对新疆伊犁和塔城地区的天山樱桃群落进行调查,比较分析两个地区天山樱桃群落物种组成的差异情况,进而揭示两个地区的天山樱桃群落特征与区系分布特征。【结果】天山樱桃群落的整体物种丰富度较低,研究区域内仅记录到23科48属48种维管束植物,其中,伊犁地区各样地内共记录到17科36属36种植物,塔城地区各样地内共记录到15科31属31种植物,群落中的优势种主要为蔷薇科Rosaceae、禾本科Poaceae、菊科Asteraceae植物。研究区内共计48个植物属,可以划分为11个分布区类型;温带属性分布类型的植物属共有30个,占整个研究区域内植物属总数的62.5%,其中具有代表性的植物属分别为樱桃属Cerasus、绣线菊属Spiraea。两个地区天山樱桃群落垂直结构的物种多样性复杂程度的表现不同,伊犁地区天山樱桃群落不同结构层次的物种多样性复杂程度的高低顺序表现为:草本层>灌木层>乔木层。塔城地区天山樱桃群落不同结构层次的物种多样性复杂程度的高低顺序表现为:灌木层>草本层>乔木层。【结论】从整体上看,天山樱桃群落的物种组成结构较为简单;从不同地区来看,新疆伊犁地区天山樱桃群落的物种组成比塔城地区的更为丰富。伊犁和塔城地区天山樱桃群落的垂直结构层次明显,植物区系均以温带属性为主。
【Objective】To study the species composition and floristic distribution characteristics of Cerasus tianschanica communities in Ili and Tacheng regions of Xinjiang,and to provide theoretical basis for the protection and sustainable utilization of this rare species.【Method】A typical sample survey method was used to investigate the C.tianschanica community in Ili and Tacheng regions of Xinjiang,and the species composition differences of two areas were compared and analyzed,so as to reveal the community characteristics and distribution characteristics of C.tianschanica in these two areas of Xinjiang.【Result】The overall species richness of the C.tianschanica was low,only 48 vascular plants belonging to 48 genera and 23 families were recorded in the study area,among them,36 species belonging to 36 genera and 17 families were recorded in Ili area,and 31 species belonging to 31 genera and 15 families were recorded in Tacheng area,community dominant species mainly Rosaceae,Asteraceae and Poaceae.A total of 48 plant genera in the study area were divided into 11 distribution types.There were 30 plant genera with temperate attribute distribution types,accounting for 62.5%of the total number of plant genera in the entire study area.The representative genera were Cerasus and Spiraea.The species diversity complexity of vertical structure of C.tianschanica community in two regions was different.The order of the complexity of species diversity at different structural levels of the C.tianschanica community in Ili region was as follows:herb layer>shrub layer>arbor layer.The order of the complexity of species diversity at different structural levels of the C.tianschanica community in Tacheng region was as follows:shrub layer>herb layer>arbor layer.【Conclusion】On the whole,the species composition structure of C.tianschanica community is relatively simple.From the perspective of different regions,the species composition of the C.tianschanica community in Ili region of Xinjiang is more abundant than that in Tacheng region.The vertical structure of C.tianschanica community in Ili and Tacheng regions is obvious,and the flora is mainly temperate.
