CQS.FFH-2型E601自动水面蒸发器比测分析

Comparison and Analysis of CQS.FFH-2 E601 Automatic Surface Evaporator

新型自动蒸发设备配套的自动雨量器精度为0.10 mm,和普通自动雨量站设备的0.50 mm的自动雨量器相比精度大幅提高,为保证新型自动蒸发设备的在提高计量精度的同时能得到更加准确、合理的数据,目前阿克苏水文局阿拉尔水文站积极安装了新型自动蒸发技术应用,新型自动蒸发技术的应用,阿拉尔水文站是塔里木河流域的龙头站,是南疆人民的母亲河,也是中国四大盆地之一。该站进行蒸发量自动与人工业务观测。利用2021年平行观测数据,对资料的差异和相关关性以及比对系数和影响因子进行了比测、分析,结果表明;日、月蒸发量差值基本满足正态分布,近87组比测数据自动观测和人观测数据,自动与人工观测数据之间存在很好的线性很好的关系。逐日蒸发相关性为0.86、旬蒸发相关性为0.95,在定性对比观测系数的影响因子的基础上,进一步对气温、相对湿度、平均风速考证。为塔里木河“绿色生态走廊”,为新疆经济社会绿色高质量发展奠定水文数据支撑。

The new automatic evaporation equipment,equipped with an automatic rain gauge with an accuracy of o.10 mm,significantly improves the accuracy compared to the O.50 mm automatic rain gauge of ordinary automatic rain gauge stations.In order to ensure that the new automatic evaporation equipment can provide more accurate and reasonable data,while improving the measurement accuracy,the Alar Hydrological Station of the Aksu Hydrological Bureau has actively installed the new automatic evaporation technology.The Alar Hydrological Station is the leading station in the Tarim River Basin,the mother river of southern Xinjiang and one of the four major basins in China.The station conducts automatic evaporation volume and manual service observation.Using the parallel observation data in 2021,a comparison and analysis of data differences,correlation coefficients,comparison coefficients,and influencing factors were conducted.The results show that the difference in daily and monthly evaporation values basically follows a normal distribution.Among the nearly 87 sets of comparison data between automatic and manual observations,there is a good linear relationship between automatic and manual observation data.The correlation of daily evaporation is O.86,and the correlation of ten-day evaporation is 0.95.On the basis of the influence factor of the qualitative contrast observation coefficient,the temperature,relative humidity and average wind speed are further verified.This study provides hydrological data support for the"Green Ecological Corridor"of the Tarim River and lays a foundation for the green and high-quality development of Xinjiang's economy and society.
