摘　　要：利用和田地区4个气象站点1959-2016年日照时数、降水、相对湿度、气温、风速等气象因素的逐年气象资料,选用气候趋势系数和气候倾向率等方法定量分析和田地区光要素、水要素和风等气候要素的变化趋势,分析和田地区气候要素的变化特征。结果表明:和田地区年日照时数、年日照百分率、年降水量、年平均相对湿度、年平均气温、年平均风速的多年平均值分别为2736h、62%、45.8mm、42.6%、12.2℃、1.6m/s。日照时数、降水、平均气温呈小幅度波动上升趋势,但趋势不显著。在这58年中,日照时数、降水、平均气温呈显著上升趋势,日照百分率、相对湿度呈波动上升趋势,波动幅度不大,而年平均风速总体上呈现下降趋势。气候增暖作用分析表明和田地区气候增暖作用显著,呈现出对全球气候变暖的明显响应特征。Based on the year-by-year meteorological data of sunshine hours, precipitation, relative humidity, temperature, wind speed and other meteorological factors from 1959 to 2016 at four meteorological stations in Hotan Prefecture, the change trend of light elements, water elements and wind and other climate elements in Hotan Prefecture were quantitatively analyzed by using climate trend coefficient and climate tendency rate and other methods, and the change characteristics of climate elements in Hotan Prefecture were analyzed .The results show that the annual sunshine hours, annual percentage of sunshine, annual precipitation, annual average relative humidity, annual average temperature and annual average wind speed in Hotan Prefecture are 2 736 h, 62%, 45.8 mm, 42.6%, 12.2℃ and 1.6 m/s respectively.Sunshine hours, precipitation and average temperature show a small fluctuating upward trend, but the trend was not significant.In these 58 years, sunshine hours, precipitation and average temperature show a significant upward trend, and the percentage of sunshine and relative humidity show an upward trend with slight fluctuation, while the annual average wind speed shows a downward trend in general.The analysis of climate warming indicates that the climate warming in Hotan Prefecture is significant, presenting obvious response to global warming.
