"一带一路"西亚地区降水时空特征及空间均衡分析
Anglysis of spatial-temporal characteristics and spatial equilibrium of precipitation in West Asia area of " Belt and Road"
摘要
Abstract
Taking the main water resource areas of West Asia area in the " Belt and Road" as the research area,the precipitation data of climatic research unit(CRU)dataset from 1961 to 2016 were extracted to analyze the spatial-temporal change and spatial equilibrium characteristics of the precipitation of the research area by using the method of M-K rank correlation test and wavelet analysis.The results show that during the study period,the mean precipitation ranges from high to low are Turkey,Iran,and Arabia Peninsula.The precipitation in Turkey is slightly rising.The precipitation in Iran and Arabia Peninsula shows a decreasing trend,and the decreasing trend in Iran is more obvious.There are 8～10 a and 20～25 a cycle variations in Turkey and Iran.In the Arabia Peninsula,there are 8～10 a and 22～25 a cycle variations,of which 8～10 a is the main cycle variation.The western and middle eastern parts of Arabian Peninsula are the most scare area of precipitation in the research area.关键词
