【摘要】 土壤湿度是十分重要的气候与环境变量,它可以通过影响陆地表面与大气之间的水分与能量平衡来影响气候。准确分析土壤湿度的时空动态变化规律及其对天气与气候的影响机理,对气候、水文、与农业等相关研究都具有重要意义。本文集中讨论中国南方地区的10cm土壤湿度,分析其季节特征和气候因子降水的关系。土壤湿度与降水气温的关系分析。利用土壤湿度、降水资料在中国南方范围内做出相关分析,结果表明:土壤浅层10cm厚度层土壤湿度和降水呈正相关关系。配合1965-2005年的NASA数据,分析其区域平均的变化规律,更好的分析和了解10cm土壤湿度和中国南方气候的关系,了解土壤湿度义意。更多还原

【Abstract】 Abstract Soil moisture is very important to climate and environmental variables,it can affect the land surface and atmospheric energy balance between the water and to influence the climate.Accurate analysis of the spatial and temporal soil moisture dynamics and its effect on weather and climate mechanism,climate,hydrology,,and agriculture-related research are of great significance.This article focuses on the 10cm soil moisture in southern China,to analyze the seasonal rainfall characteristics and the relationship between climatic factors.Soil moisture between air temperature and precipitation analysis.Soil moisture,precipitation data and make relevant in the context of South China,the fruit that:10cm thick layer of soil shallow soil moisture and precipitation is positively correlated.In the NASA with the 1965-2005 data,analysis, changes of the regional average,better analysis and understanding of the 10cm of soil moisture and climate in southern China relations,better knowledge of soil moisture.更多还原
