英文摘要：

Based on an analysis of the connotation and the extension of the hydroinformation system model, the research and application of the hydroinformation acquisition and processing technique was summarized, including the basic theoretic framework for hydroinformation acquisition, the hydroinformation acquisition technique and its development, and multi-source information fusion and processing technique. Then, three key problems about the hydroinformation system, such as the technique complement for hydroinformation acquisition, the selection of information fusion algorithm, and system evaluation, were discussed.
