摘　　要：开展干旱区气候变化研究对于绿洲水土资源合理利用及经济社会可持续发展至关重要。本文以新疆阿克苏河流域平原绿洲区绿洲为例,基于小波分析方法,利用研究期典型气象站1966-2010年逐月气温、降水量和相对湿度数据,分析了主要环境因素的变化趋势、周期性规律及内在原因,结果表明:研究区气温、降水量和相对湿度呈现多周期尺度变化,气温有着0.4-1.5 a、17-32 a的周期性变化,相对湿度的变化周期为16a、5a、2a,降水量的变化周期主要为4-8 a;短时间尺度上(4-8个月尺度),温度的升高与降水量的增加呈现一致性,并且降水量增加相应会增大空气相对湿度;长时间尺度上(64个月以上尺度),气温与相对湿度呈现出更一致的负相关,并且相对湿度的增加更加滞后于降水量,相对湿度受到温度的影响开始高于降水量。it is very important to study climate change in arid area for rational utilization of water and soil resources and sustainable development of economy and society in oasis.In this project,the plain oasis of Aksu River Basin was taken as an example,based on the wavelet analysis method,the monthly temperature,precipitation and relative humidity data of typical meteorological stations from 1966 to 2010 were used and the change trend,periodic law and internal reasons of main environmental factors were analyzed.The temperature had periodic changes of 0.4-1.5 a and 17-32 a,the relative humidity had periodic changes of 16 a,5 a and 2 a,and the precipitation had periodic changes of 4-8 a;In short time scale(4-8 months),the increase of temperature was consistent with precipitation,and the increase of precipitation would increase the relative humidity;in the longterm scale(more than 64 months),the temperature and relative humidity showed a more consistent negative correlation,and the increase of relative humidity lagged behind the precipitation,and the relative humidity was affected by the temperature more than the precipitation.
