摘要
该文以岱海为研究对象,以乌兰察布市凉城县岱海镇三苏木水文站为依托,以水面蒸发物理成因为基础,根据蒸发实测资料,建立了20 cm口径蒸发器与E601型蒸发器与气温、相对湿度、水汽压、降水量、风速、地温、日照等气象要素的相关性分析,通过SPSS双侧相关性检验以及散点图趋势线分析,20 cm口径蒸发器监测蒸发量时更灵敏,与气象要素相关性更好,对于气象要素的变化反应更敏感;气象要素对蒸发量的影响中,对蒸发量影响最大的是最高地面温度,其次是日照时数、平均相对湿度和最高气温,最高地面温度、最高气温越高、日照时数越长、风速越高,蒸发量越大;平均相对湿度越大,环境中水汽含量越高,蒸发量越小。
This article takes the waters of Daihai as the research object,and relies on the Sansumu Hydrological Station in Daihai Town,Liangcheng County,Wulanchabu City.Based on the physical causes of water surface evaporation and actual evaporation data,a correlation analysis between a 20cm caliber evaporator and an E601 type evaporator and meteorological factors such as temperature,relative humidity,water vapor pressure,precipitation,wind speed,ground temperature,and sunlight was established.SPSS bilateral correlation test and scatter plot trend line analysis were used.The 20cm diameter evaporator is more sensitive when monitoring evaporation,has better correlation with meteorological elements,and is more sensitive to changes in meteorological elements;Among the impacts of meteorological elements on evaporation,the maximum ground temperature has the greatest impact on evaporation,followed by sunshine hours,average relative humidity and maximum temperature.The higher the maximum ground temperature and maximum temperature,the longer the sunshine hours,the higher the wind speed,and the greater the evaporation;The higher the average relative humidity,the higher the water vapor content in the environment,and the smaller the evaporation.
