Abstract:Guided by the top design of informatization of Changjiang Water Resources Commission, we summarize the basis of informatization for the current stage of Digital Yangtze River, mainly focusing on fulfilling the requirements of integrated management in Yangtze River basin that has become increasingly complex. We put forward the idea of programming Intelligent Yangtze River which aims at promoting thorough perception, comprehensive interconnection, in-depth integration, resources sharing, smart applications and ubiquitous services. It outlines an objective system of Yangtze River featuring Safety, Green, Harmony, and Beauty. An initial framework is established, which consists of a dynamic perception system, an interconnected big data system, a smart application support system, an intelligent application system, an operational environment system and a safety and security system. A three-stage implementation plan sets out a short-term (from 2018 to 2020 ) goal of foundation building, an interim (from 2021 to 2025)goal of achieving preliminary results , and long-term (from 2025 to 2035) goal of top-down implementation, based on which the short-term working processes are sorted out first. Constructing a comprehensive dispatching support system of key water projects in Yangtze River Basin and capacity building of the full-coverage water monitoring are the two backbone projects that provide basis for launching the intelligent Yangtze River plan, and paving the way for the realization of long-term goals and further supporting Yangtze River harnessing in the new era. The reference for implementation of “Intelligent Yangtze River”plan is provided.
