| 摘 要： | 以玉米田实测数据为依据,对农田大气水汽稳定同位素组成δνv的影响因素及其相互关系进行了研究,据此发现,大气降雨、空气温度、相对湿度及平均风速是影响农田生态系统大气水汽稳定同位素组成δv的重要环境因素;其中空气温度与大气水汽稳定同位素组成δv拟合呈线性关系;相对湿度、平均风速与大气水汽稳定同位素组成δv拟合呈对数关系,其相关性均极高。 |
| 关 键 词： | 稳定同位素组成 影响因素 关系拟合 |
Atmospheric Water Vapor Stable Isotope Composition δv Influence Factors Analysis |
|
| Abstract: | After study the measured data on the farmland of atmospheric water vapor stable isotope composition δv influencing factors and their relationship,and accordingly found that: the atmosphere of rainfall,air temperature,relative humidity and average wind speed were important environmental factors,which influenced the water vapor stable isotopes composition δv of farmland ecological system;the air temperature and water vapor stable isotope composition δv were fitted in a linear relationship,while relative humidity,average wind speed were fitted in a logarithmic relationships with water vapor stable isotopic composition δv,and also the statistics showed that the correlation was admirable. |
| Keywords: | stable isotopic composition influence factors fitting relationship |
