摘要：该文应用年轮气候学理论和方法对毛乌素沙地小叶杨和北京杨年轮结构的变化特征及其与月平均气温和月降水量的响应关系进行了分析.结果表明,小叶杨和北京杨的年轮宽度指数序列的变动模式很相似,但小叶杨年轮宽度指数的变动幅度比北京杨大得多,这与毛乌素沙地的气候变化大的特点相一致.用月平均气温和月降水量作为气候因子建立的响应函数模型,能够说明2种杨树年轮宽度和导管腔径变化的46%～5 5 % .小叶杨的年轮宽度和导管腔径对月平均气温及月降水量的反应基本上是一致的.当年2月气温过高会抑制小叶杨年轮宽度和导管腔径的增加,而夏季降水量和气温对其年轮宽度和导管腔径增大有明显的促进作用.北京杨的年轮宽度和导管腔径对月平均气温及月降水量的反应不一致。
The response of tree-ring structure to the variation of average monthly temperature and precipitation on Populus simonii and P. × beijingensis collected from the Mu Us Desert, Inner Mongolia, was studied using dendrochronology techniques. The results showed: the patterns of variation in the RW (ring width) index of P. simonii was similar to that of P. × beijingensi, while the range of variation of the former was bigger than that of latter. This coincides with the big climate variation in the Mu Us Desert. The response model built up with monthly average temperature and precipitation could explain 46% to 55% of RW and VLD (vessel lumen diameter) variation. The variation of RW and VLD of P. simonii had a similar response to average monthly temperatures and precipitation. Too high temperatures in February would restrain the increment both in RW and VLD, while the precipitation and temperature in summer could accelerate evidently an increment in RW and VLD. Responses of RW of P. × beijingensis to average monthly temperature and precipitation did not quite agree with that of VLD, and neither RW nor VLD had significant responses to climate change.
