Abstract:

 Traditional hydraulic engineering has some deficiencies such as the ignorance of integrality and ecological function of the watershed, resulting in unavoidable negative effects on the watershed ecosystem and the sustainable development of resources. Therefore, the concept of ecohydraulic engineering is proposed. With basic thoughts to resolve the problem and to achieve harmonious coexistence of human and nature, we should insist on sustainable development, keep selforganization and selfrestoration of ecosystem, attach importance to the integrality of watershed, preserve the diversity of biology, and maintain water accessibility; thus we can construct the basic principles of ecohydraulic engineering. Moreover, the health check of the watershed ecosystem, design and management of the ecohydraulic structures, and ecological restoration and reestablishment of damaged watershed ecosystem are the main research aspects for the construction of ecohydraulic engineering.

Key words: traditional hydraulic engineering, ecohydraulic engineering, transformation trend
