In order to realize a new fixed ice regime detection method，according to the characteristic difference rule of resistance and temperature of air，ice and water，through stratified detection, resistance and temperature data are obtained to determine the ice thickness，ice internal temperature gradient and water level under the ice. On this basis，a kind of resistance-temperature ice regime sensor and an automatic detection system are developed，which are applied to the Antarctic expedition and the ice forecast research of the Yellow River. The application results indicate that the proposed system is completely feasible in ice regime automatic detection.
