丹江口水库水面蒸发监测站的建设及运行

摘要

In the light of the problems of without measured water surface evaporation data in Danjiangkou Reservoir and no reli-able evaporation recording instrument for floating evaporation station in China,starting from hydrological gauging,we introduce the site selection and monitoring parameters selection scheme for the establishment of floating evaporation station.In addition,we put forward the information acquisition and transmission scheme for evaporation and related parameter from the perspective of modern transducers,communication and computer technology.According to the scheme,the floating evaporation station in Dan-jiangkou Reservoir was completed in January,2017 and has operated steadily for about half year and the self-recorded data are in good agreement with the manual observed data,which proves that the monitoring scheme is scientific and feasible.Finally,we put forward some improvement suggestions according to the actual situation%针对丹江口水库水面蒸发量无实测资料,国内水面漂浮蒸发站无成熟自记仪器的现状,从水文监测的专业角度介绍了水面漂浮蒸发站的选址方案和监测参数的选择方案,从现代传感器、通信、计算机技术的角度提出了蒸发量及相关参数信息的采集与传输方案.根据该方案建成的丹江口水库水面漂浮蒸发站于2017年元月建成,运行将近半年,系统运行稳定,设备自记数据与人工观测数据吻合良好,证明该监测方案是科学可行的,并根据实测情况提出了完善建议.
