摘　　要：[目的]研究塔里木河中游柽柳属地上生物量分布规律,并求出柽柳属地上生物量估算的最佳模型。[方法]利用最常用的取样方法—PCQ方法,在塔里木河中游的5个样带进行取样。在野外调查工作的基础上,利用Evangelista等的模型,建立了适合该地区柽柳属的线性回归模型,并分析了塔里木河中游柽柳属地上生物量分布规律。[结果]所建模型适合该研究区柽柳地上生物量的估算。从地上生物量分布规律可知,地下水是决定该地区柽柳地上生物量分布的关键生态因子。[结论]为柽柳属植物生物量估算研究提供了理论依据。[Objective] The purpose was to research the distribution characteristics of Tamarix species above-ground biomass of Tarim River＇s middle reaches and to find out best-fit linear-regression model of Tamarix species in this area.[Method] By dint of the most common sampling method PCQ,five samples in the middle reaches of Tarim River were collected.The best-fit linear-regression model of Tamarix species of this area was set up,based on the fieldwork and the model of Evangelista and obtained the distribution rules of Tamarix species of Tarim River＇s middle reaches.[Result] The result indicated that this model fitted for the estimation of aboveground biomass of the study area.According to the distribution rules of aboveground biomass,it was clear that underground water was the major element which decided the distribution of aboveground biomass.[Conclusion] The study provided theoretical basis for the calculation of biomass of Tamarix.
