Abstract: In the current context of territorial and spatial governance and control, small and medium-sized rivers regulating in towns and villages are facing a number of tangible and intangible challenges, such as conflicts with territorial space elements, environmental impacts of cross-infrastructure projects, and insufficient public awareness among local villagers.With investigations and summaries on small and medium-sized rivers regulation conditions in the Yangtze River Delta, we analyzed the reasons of project constructions delaying and highly inputs, then proposed countermeasures:(1) Strengthening the overall planning and optimization of natural resource elements such as mountains, waters, forests, fields, lakes, grass and sand in the national territorial spaces;(2) Formulating hierarchical and phased implementation plans as well as implementation policies for the composite utilization of national territorial spaces;(3) Establishing cross-industry and cross-department collaborative design and joint approval mechanisms; clarifying the requirements and technical guidelines for synchronous design of infrastructure projects;(4) Enhancing villagers′ public participation to get full play to the benefits of river construction projects;(5) Promoting and applying new digital and intelligent technologies.
