摘要

[目的] 分析胡杨生长期内各环境因子对树干液流速率的影响程度

为干旱区自然植被耗水量的计算提供了新的方法和科学依据。[方法] 对塔里木河下游2012单木胡杨整个生长季内树干液流以及空气温度、风速、有效光合辐射强度、空气湿度、土壤温湿度等环境因子进行连续观测。[结果] 胡杨在整个生长季内的液流呈单峰波动曲线

有明显的昼夜变化规律;在生长期内

不同的观测尺度下

影响胡杨液流速率的环境因子不同。回归分析结果表明

对于瞬时液流流速

相关性较大的环境因子主要是大气温度、10 cm深处的土壤温度;对于日液流量

主要影响因子为太阳净辐射;对于月液流量

主要影响因子为大气温度和太阳净辐射。[结论] 研究区内胡杨生长受大气温度和太阳净辐射影响程度较其他因素大

并且回归方程具有很高的拟合精度。

Abstract

[Objective] The influences of environmental factors on sap flow rate of Populus euphratica were analyzed to provid method data base for the calculation of water consumption by natural vegetation in arid area.[Methods] The trunk sap flow of Populous euphratica at the lower reaches of Tarim River was measured continuously during the whole growth season in 2012 and its responses to environmental factors were analyzed.[Results] The sap flow of Populus euphratica presented an unimodal curve

with obvious day and night variation rhythm. During the growth season

the relations between sap flow rate and environmental factors depended upon the temporal scales. Regress analysis showed that when observed at less hour scale

sap flow were associated closely with air temperature and soil temperature at depth of 10 cm. However

on daily scale

solar radiation was the major influencing factors; and on monthly scale solar radiation and air temperature were the major influencing factors.[Conclusion] The major factors assocated with sap flow of Populus euphratica are air temperature and solar net radiation

and the regressions of them with the sap flow rate were fitted wells.
