摘　　要：以塔里木河下游的胡杨为研究对象,探讨了胡杨生物量以及经济价值的变化趋势。基于2001—2016年塔里木河下游胡杨的调查及模拟资料,借鉴生物量估算方法,首先对胡杨生物量变化进行了模拟;其次,依据胡杨生物量变化特征和价值评估方式,定量评价了塔里木河下游胡杨的经济价值。结果如下:(1)建立了胡杨胸径与年龄间关系模型A=12.711/(1+3.339×e^(–0.208D))和胡杨单株生物量模型F=128.09(D^2h)^(0.6318)(R^2=0.892;F=285.35)。(2)估算了生态输水以来各年份胡杨总生物量,起始年份2001年胡杨总生物量约为21.029×10^(4 )t,平均生物量约为2.401 t·hm^(–2)。(3)胡杨年际新增价值量最大值出现在2006年为6.746×10~8元,2009年、2011年、2014年胡杨新增价值量均小于0.08×10~8元,并且新增价值量与输水量呈极显著正相关关系。Populus euphratica in the lower reaches of Tarim River was took as the research object,and the variation trend of biomass and economic value of Populus euphratica was discussed.Based on investigated and simulated data of Populus euphratica in the lower reaches of Tarim river from2001to2016,with the estimated methods referenced,change of Populus euphratica biomass was simulated firstly.Secondly,according to the characteristics of biomass and the pattern of value assessment,ecological value of Populus euphratica was assessed quantitatively.The results are as follows.①The relational model A=12.711/(1+3.339×e-0.208D)which between DBH and age of Populus euphratica was established,so as the biomass model of single plant that F=128.09(D2h)0.6318(R2=0.892;F=285.35).②The total biomass of Populus euphratica forest in every year was estimated since the starting of ecological water transport.Total biomass was21.029×104t in2001,with the average biomass about2.401t·hm-2.③The biggest interannual new increased value was6.746×108yuan in2006;however,the new increased values in2009,2011and2014were all below0.08×108yuan.What's more,there was a significantly positive correlation between new increased value and water carrying capacity.
