摘　　要：利用1981—2008年NCEP-CFSR资料,将中国及其周边地区分为3个区域,分析了其夏季降水量和土壤湿度的时空分布特征。结果表明,中国及其周边地区夏季的降水量和土壤湿度均呈南部大、中部小、北部居中的特征;中南半岛沿岸、印度半岛西岸、云贵高原、台湾以及缅甸至孟加拉国一带降水量最大,朝鲜半岛及俄罗斯南部次之,而中国中西部、印度大沙漠、萨雷伊希科特劳沙漠等地区降水量最小;青藏高原东南部、云贵高原、东南丘陵、长江中下游以南、印度西高止山脉以及朝鲜半岛土壤湿度最大,中南半岛、俄罗斯南部、青藏高原西部、华北平原、东北平原以及印度半岛东部次之,而中国中西部、印度大沙漠、萨雷伊希科特劳沙漠等地区土壤湿度最小;1981—2008年中、北部土壤湿度呈下降趋势,南部土壤湿度在28年间持平,而3个区域的降水量均呈下降趋势,这可能与全球变暖有一定的联系。We used the NCEP-CFSR data from 1981 to 2008,and divided China and its surrounding areas into three regions,to analyze the spatial and temporal distribution characteristics of summer precipitation and soil moisture.The results showed that the summer precipitation and soil moisture in China and its surrounding areas were the largest in the south,the second in the north and the smallest in the central part.The precipitation was greatest along the coast of the Indo-China Peninsula,the West Bank of the Indian Peninsula,the Yunnan-Guizhou Plateau,Taiwan,and Myanmar to Bangladesh.The Korean Peninsula and the southern part of Russia followed,while the precipitation was smallest in the Midwest China,the Indian Desert,and the Saray Ishi Kotau Desert. The southeastern Qinghai Tibet Plateau,Yunnan Guizhou Plateau,southeastern hills,the middle and lower reaches of the Yangtze River,the West India mountains and the Korean Peninsula had the largest soil moisture,followed by the Indochina Peninsula,southern Russia,the western Tibetan Plateau,the North China Plain,the Northeast Plain,and the eastern part of the Indian Peninsula,while the Central and Western China,the Indian Desert,the Saray Ishitova Desert,etc.had the smallest soil moisture.Besides,from 1981 to 2008,the soil moisture in central and northern regions showed a downward trend,and remained flat in 28 years in the southern region,while the precipitation in all three regions showed a downward trend,which may be associated with global warming.
