Abstract:
At the present stage, the basic theoretical knowledge and systematic research on national water network is still weak, which largely restricts the scientific planning and construction of national water network. To this end, the basic concepts of network, water network and national water network are analysed from the basic cognition of national water network. The basic problems of water network are initially explored in terms of the main features such as water network structure, bearers, evolutionary laws, functional roles, and type division. The target guidelines was putforward for the construction of water network with the core objective of realising a healthy water cycle, the promotion of the six balances as the basic guideline, and the principles of "real need, ecological safety, and sustainability" for the demonstration of major projects. A new trend in the construction of future water networks is envisaged, with a view to providing support for the scientific construction of national water networks at the theoretical level.
