山西蟒河珍稀植物群落谱系结构研究
|
摘要
[目的]探讨山西蟒河珍稀植物的濒危机制。[方法]以山西蟒河国家级自然保护区珍稀植物群落为研究对象,分别对5个空间尺度(100、400、900、1 600和2 500 m2)和6个径级(DBH<5 cm、5 cm≤DBH<10 cm、10 cm≤DBH<15 cm、15 cm≤DBH<20 cm、20 cm≤DBH<25 cm、DBH≥25 cm)的谱系结构及其在不同研究方向上的改变规律进行分析,据此分析群落成因。[结果]珍稀植物群落谱系聚集程度和空间尺度是正相关的。随着径级的增大,群落谱系整体上都表现为谱系聚集,谱系结构聚集程度相对平稳。[结论]山西蟒河珍稀植物群落在不同空间尺度和不同径级下都表现出显著的谱系结构,说明在蟒河珍稀植物群落构建过程中,生态位理论的作用更加重要,而中性理论的谱系随机并不相符。
[Objective]The aim was to explore the endangered mechanism of rare plant communities in Shanxi Mang River. [Method]As the research object of rare plant community for the national natural protection area of Mang River,Shanxi,it was analyzed the change rules of five space sizes( 100,400,900,1 600 and 2 500 m2) and six diameter classes( DBH < 5 cm,5 cm≤DBH < 10 cm,10 cm≤DBH < 15 cm,15 cm≤DBH < 20 cm,20 cm≤DBH < 25 cm,DBH≥25 cm) for the phylogenetic structure of plant communities and different researching directions to research the cause of the construction of communities. [Result] The degree of phylogenetic aggregation for the rare plant communities was bigger and bigger with the improvement of diameter class. The community revealed the phylogenetic aggregation,and the aggregation degree of phylogenetic structure was relatively steady. [Conclusion]In the research,it is the phylogenetic structure at different space sizes and diameter classes for the rare plant communities of Mang River,Shanxi,all of these reveal that the roles of niche theory is more important and the communities of neural theory is inconsistent at random.
