中文摘要	应用和田地区六个代表气象站1960-2008年逐月平均气温、降水量和相对湿度资料, 采用线性倾向估计、Mann-kendall、累计距平、Morlet小波等方法分析了49a来和田地区气温、降水、相对湿度三要素年及四季的时空变化、突变及周期特性, 结果表明:(1)自西向东呈现出气温下降、降水减少、湿度减小的分布规律;(2)气温、降水、相对湿度呈线性增暖、增多、增大的变化趋势, 尤以冬季气温增暖、相对湿度增大, 夏季降水增多较为明显;(3)气温、降水、相对湿度均表现出明显的年代际和年际周期变化, 年际周期尺度较年代际振荡复杂且时期性明显;(4)49a来气温、降水、相对湿度均有突变发生, 各要素年、季突变点及突变性有差异;(5)三要素之间, 气温与降水、气温与相对湿度成反相关关系, 降水与相对湿度成正相关关系.
英文摘要	Using the average monthly temperature, precipitation and relative humidity information of six weather stations in Hotan region during 1960-2008, a linear tendency, Mann-kendall, a total anomaly and Morlet wavelet analysis methods were used to analyze the three elements of 49a temperature, precipitation and relative humidity, the space-time of four seasonal change, mutation and cycle characteristics in Hotan region. Results showed that:(1)From west to east, showing a drop in temperature, precipitation and humidity;(2)temperature, precipitation and relative humidity had a linear increasing trend, temperatures and relative humidity increases in winter especially, and the more obvious increasing precipitation in summer;(3)temperature, precipitation and relative humidity had significant changes in inter-decadal and inter-annual cycle;inter-annual cycle had more complex and significant inter-decadal oscillation period than inter-decadal cycle;(4)mutations of temperature, precipitation and relative humidity occurred during 49a, the point mutation of year and seasonal elements and the mutation were differend;(5)between the three elements, temperature and precipitation, temperature and relative humidity had a anti-correlation, precipitation was positively related to relative humidity.
