中文摘要	应用FLGS-TDP插针式热扩散探针技术,对策勒绿洲的矮化红枣树干液流进行长期监测,同步记录试验地周围的气象因子,分析矮化红枣树干液流变化规律,建立树干液流与环境因子之间的关系模型.结果表明:液流日变化呈单峰曲线,夏季偶尔会出现双峰曲线;天气条件对液流变化有影响,晴天条件下的液流速率最大,沙尘天气次之,雨天液流速率最低;不同季节间的液流速率差异显著,夏季液流启动于06:30左右,比春季和秋季的液流启动时间早;夏季树干液流持续时间最长,春季和秋季液流持续时间相对较短,夏季液流速率峰值最高,春季和秋季峰值偏低;生长期内液流速率与太阳辐射强度、大气温度呈显著正相关关系,与空气相对湿度呈显著负相关关系; 各种环境因子中太阳辐射强度对液流速率的影响最大,相关系数为0.927,其次是大气温度,相关系数为0.115,空气相对湿度的影响最小,其相关系数为0.548.通过对矮化红枣树干液流进行监测,研究分析矮化红枣的水分消耗特征,为绿洲农业水资源分配管理提供数据支撑。
英文摘要	In this paper,the characteristics of sap flow of the dwarf red jujube trees in the Qira Oasis were analyzed,and the relationship between the sap flow and environmental factors was researched. The results showed that the curve of daily variation of sap flow was unimodal,and it was occasionally bimodal in summer. Weather conditions affected significantly the change of sap flow,the sap flow rate was the highest on sunny day,then under sand and dust weather, and it was the lowest on rainy day. The seasonal difference of sap flow rate was significant, the sap flow started earlier in summer than that in spring and autumn; the duration of sap flow was the longest in summer,it was relatively short in spring and autumn; the peak value of sap flow was the highest in summer but low in spring and autumn. There was a significantly positive correlation between the sap flow rate and the solar radiation intensity and air temperature,but a significantly negative one between the sap flow rate and the relative humidity. Among the environmental factors,the effect of solar radiation intensity on the sap flow rate was the highest,then that of air temperature,and that of the relative humidity was the lowest.
