和田市农业气候资源变化趋势探析

Analysis on the Change Trend of Agricultural Climate Resources in Hotan City

利用1999-2018年和田市51个气象站20余年的气候资料,应用线性气候倾斜率方法对一年四季光热水等主要农业气候资源要素进行诊断分析,应用Mann-Kendall方法完成对主要农业气候资源要素的观测。结果表明:近20年来和田市增温趋势明显,热量资源愈加丰富,特别是年最低温增幅明显,冬季增温幅度比春夏秋季大,日照时数和降水量均呈增加趋势。

Based on the climate data of 51 weather stations in Hotan city for more than 20 years from 1999 to 2018,the linear climate tilt rate method was used to diagnose and analyze the main agricultural climate resource elements,such as light and hot water in four seasons,and Mann Kendall method was used to complete the observation of main agricultural climate resource elements.The results show that the warming trend is obvious in Hotan city in recent 20 years,and the heat resources are more and more abundant In addition,the annual minimum temperature increased significantly,and the temperature in winter was larger than that in spring,summer and autumn,and the sunshine hours and precipitation showed an increasing trend.
