利用库车绿洲1951—2014年气象观测资料,应用Morlet小波处理和 R/S分析方法,进行气温变化趋势分析.结果表明,小波处理方法能够较好地突出历史时间序列的变化特征;Hurst指数可以分析出未来气候演变趋势,总体而言,平均最高温度将会缓慢降低,而平均最低温度将会缓慢升高,一方面有利于研究区农作物的生长,但同时也有利于害虫越冬,森林、农田将面临威胁.
Using the meteorological observation data of Kuqa Oasis from 1951 to 2014, Morlet wavelet analysis and R/S analysis were used to analyze the trend of temperature change.The results showed that the wavelet processing method could better highlight the changing features of historical time series.Hurst index could analyze the trend of future climate evolution.Overall,the average maximum temperature would slowly decrease,while the average minimum temperature would slowly increase.On the one hand it was conducive to the growth of crops in the study area, but also conducive to the pests overwintering.Forests and farmland would be threatened.
