陆地水文传感器的现状与发展趋势

Current situation and development trend of hydrological sensor

温、深、流是陆地水文最基本的3个要素。传感器是获取水文信息的关键器件,然而我国水文传感器发展相对滞后。为促进水文传感器国产化,本文着重选取温、深、流3类陆地水文传感器为代表,详细比较了现有传感器的优缺点及适用范围,重点分析了温、深、流3类传感器的发展趋势。

. Temperature , depth and flow velocity are the basic elements of hydrology. The sensor is the key device of accessing to hydrological information. However, hydrological sensors make little progress in our country. In order to promote hydrological sensor localization, taking three kinds of hydrological sensors of temperature, depth and flow velocity as representatives, this paper compares advantages, disadvantages and application of existing sensors in detail, and focuses on analyzing development tendency of three kinds of the hydrological sensor.
