中文摘要：

根据对额尔古纳河流域冰下水位监测的需求，本文利用基于空气、冰与水电阻特性差异的冰水情检测原理，设计了一种全新的适合额尔古纳河河道的冰下水位自动测报系统，整个系统由现场冰下水位数据采集和数据处理中心两部分组成，通过对冰水情信号的采集和传输实现了对河道冰下水位、冰厚值的定点连续自动测报。经过试验证明该系统具有工作状态良好、自动化程度高、信息传送准确和监测连续等优点。试验数据为相关部门提供了第一手的界河冰下水位的数据情况。

According to the requirements of the Argun River Basin water level monitoring under the ice. This paper based on the prin- ciple of the ice condition detection with the difference properties of the air, ice and water resistance, design a suitable water level under the ice automatic detection system for the Argun river course, and realize the water level under ice and ice thickness value continuous automatic forecasting.
