中文摘要	农田铺设地膜是目前我国干旱半干旱地区采用较广泛的耕作方式。为了研究大面积地膜覆盖对东亚区域的气候效应,基于地膜试验观测与理论研究,建立了地膜覆盖的地气水热传输过程模型,并将地膜覆盖农田下垫面模块引入区域气候模式RegCM 4和WRF模式中,对17 a夏季气候进行模拟试验。通过RegCM 4模式输出的降水量、土壤温度、土壤湿度、感热通量和潜热通量等参量,与试验观测值、理论值进行对比,并通过WRF模式输出结果进行验证。结果表明:加入地膜覆盖农田下垫面模块的区域气候模式能够较为真实的描述其下垫面特征。进一步分析模拟结果发现,通过地膜覆盖影响近地面水热传输并作用于区域位势高度场、风场,进而影响大范围水汽输送,最终造成我国西北、华南地区降水减弱,西南地区和淮河流域降水增加。
英文摘要	As an effective way of farming,plastic film mulching on farmland is widely used in arid and semiarid areas in China.In order to study the climate effect of plastic film mulching on farmland in East Asia,in this research a model of heat-water transfer process on mulched farmland was developed based on carrying out the experimental observation and theoretical research and introducing the mulched farmland module into RegCM 4 and WRF model to carry out a climate simulation experiment in summer for 17 years.The outputted parameters,such as precipitation,soil moisture content,surface soil temperature,sensible heat flux and latent heat flux,were compared by RegCM 4 model with the experimental observation and theoretical value,and the parameters were verified by the outputted results of WRF model.The result showed that,after mulching plastic film,the regional climate model can be used to exactly describe the characteristics of farmland underlying surface.Further comparison revealed that the potential field and wind field could be changed by mulching plastic film through influencing heat and water transfer near surface,and the water vapor transmission was affected,resulting in a reduction of precipitation in northwestern and southwestern parts of China,but an increase of precipitation in southwest China and the Huai River Basin.
