| 摘 要： | 基于样地调查方法对塔里木河上游阿拉尔、新其满、英巴扎断面河岸胡杨群落特征及胡杨种群结构与侧枝生长量进行了研究和分析。结果表明:①塔里木河上游河岸胡杨群落物种组成较简单,共有16种植物,分属10科16属,其中乔木1种、灌木和草本分别为6种和9种。3个断面发现的物种种数分别为6种、8种和12种,共有种为胡杨(Populus euphratica)、多枝柽柳(Tamarix ramosissma)和铃铛刺(Halimodendron halodendron)。②各断面胡杨群落物种多样性指数较低,物种丰富度指数、Simpson指数和Shannon-Winner指数大小顺序为英巴扎,新其满,阿拉尔。③胡杨种群主要以幼龄个体为主,种群树高、胸径为底宽上窄增长型结构。④1998—2002年各断面胡杨枝轮生长量波动较大,2003—2007年生长量呈下降趋势。 |

| Abstract: | By the quadrat survey method we studied the characteristics of the communities and the structure of population of Populus euphratica Oliv in upper reaches of Tarim River in the Alaer, Xinqiman and Yinbazha sections of upper reaches of Tarim River and analyzed the growth of P. euphratica through measurement of branches diameter increment. The results showed: (1) The species structure of P. euphratica in upper reaches of Tarim River was simple and there were 16 species belonging to 16 genera of 10 families. The species number of the arbor, shrub and herbage was 1, 6 and 9, respectively. The number of plant species in the three different sections was 6, 8 and 12, respectively, and the common species in the three sections were Populus euphratica.Oliv, Tamarix ralnosissima and Halimodendron halodendron. (2) The diversity index of P. euphratica community in the three sections was little and the abundance index, Simpson index and Shannon-winner index decreased in order of Yinbazha, Xinqiman and Alaer sections. (3) P. euphratica population in upper reaches of Tarim River was based on young individuals and the tree height and DBH structure showed it was a growth-oriented population. (4) The branch diameter increment of P．euphratica in different sections fluctuated greatly from 1998 to 2002, and it declined from 2003 to 2007. |
