塔里木河干流胡杨种群结构及空间分布特征
|
摘要
采用相邻格子样方法,在塔里木河干流设置了10个100 m×100 m的样方地,从种群的径级结构、静态生命表、分布格局3个方面分析了胡杨(Populus euphratica)种群的龄级结构特征及空间分布格局。结果表明,由径级结构分析可知,塔里木河干流幼龄胡杨数量在种群中所占比例较高(Ⅰ、Ⅱ级占33.47%),属于增长型种群。在静态生命表中,Ⅰ、Ⅱ级胡杨的死亡率分别高达39%、50%,Ⅲ级的胡杨生命期望值最高,为10.04。胡杨种群分布格局为集群分布,干流纵向胡杨种群的聚集强度为上游<中游<下游,干流横向3 000 m内胡杨种群的聚集强度大致相同。
Using the adjacent grid-like method, 10 plots of 100 m×100 m were set up in the main stream of Tarim river,the quantitative characteristics of Populus euphratica population were analyzed from the aspects of the diameter structure, static life table and distribution pattern of the population, and spatial distribution pattern. The results showed that according to the analysis of the diameter-level structure, the number of young Populus euphratica in the mainstream of the Tarim River was relatively high in the population(Ⅰ～Ⅱ class was 33.47%), belonging to the growth population. In the static life table, the mortality rates of Populus euphratica Ⅰ～Ⅱ class was as high as 39% and 50%, respectively, and the life expectancy of Populus euphratica Ⅲ class was the highest, which was 10.04. The distribution pattern of Populus euphratica population was cluster distribution. The aggregation intensity of Populus euphratica population in the main stream was upstream
