Abstract: In order to construct the technology database of river health restoration and management and apply the technical achievements produced in recent years to the watershed system management, based on the summary and review of the restoration and management technologies in Liaohe Conservation area, the storage process design of the river health restoration and management technologies in Liaohe Conservation Area was proposed. The process was composed of four main procedures: technology collection, classification, evaluation and storage review. First of all, the achievements of the National Water Pollution Control and Treatment Science and Technology Major Project were collected and sorted out, and classified according to their technical properties. Secondly, the evaluation results of technology innovation, technology leadership and technology readiness were used as the storage conditions for technologies. Finally, the technologies with innovation evaluation score greater than 60, technology leadership evaluation score greater than 50, and restoration technologies with readiness level 6 or above, management technologies with readiness level 4 or above, were formed as a technology list and were included in the technology database.
