摘要
[目的]分析塔里木河流域荒漠柽柳生物量特征。[方法]该研究针对塔里木河流域荒漠柽柳的生物量进行研究,采集不同盖度下的柽柳样本,分析其地下、地下生物量分布特征。[结果](1)柽柳地上生物量随着覆盖度的增加而增加。(2)以标准株柽柳地上生物量为x,地下生物量为y,进行方程拟合得出地上-地下生物量之间的异速方程y=5.517 7x0.834 6(R2=0.820 8)。(3)柽柳灌丛地上生物量与灌丛地径、株高有极强的正相关性,生物量与冠幅在0.05水平上相关性显著。[结论]该研究为监测评估以灌木柽柳为主的生态系统服务功能提供了基础数据。
[Objective]The desert Tamarisk chinensis characteristics of biomass in Tarim River were studied.[Method]The study was conducted research on biomass of desert Tamarisk chinensis,and samples collected under different coverage,the aboveground,underground biomass distribution were analyzed. [Result]（1） Tamarisk chinensis aboveground biomass increases with increasing coverage increases.（2） With standard strains of aboveground biomass of Tamarisk chinensis as x,underground biomass for y,the allometric equation was： y = 5. 517 7x0. 834 6（R2= 0. 820 8）.（3） Plant height and diameter have a very strong positive correlation with aboveground biomass. Biomass with crown width correlation is significant at the 0. 05 level. [Conclusion]The study provides a theoretical basis and data support for the valuation of ecosystem services.
