River Ecological Corridor: A Conceptual Framework and Review of the Spatial Management Scope
2. Theoretical Concepts and Structure
2.1. Concept Discrimination
2.1.1. Ecological Corridor
2.1.2. River Ecological Corridor
2.2. Structure and Function
2.2.1. Structure and Composition
3. The Relationship between River Ecological Corridor and Territorial Space Management and Control
3.1. River Ecological Corridor and River Shoreline
3.2. River Ecological Corridor and “Three Control Lines”
3.3. River Ecological Corridor and Other Scope Lines
4. The Scope of River Ecological Corridor Based on Territorial Space Control
4.1. Spatial Management and Control of the River Ecological Corridor Based on Shoreline
4.2. Spatial Management and Control of the River Ecological Corridor Based on Aquatic Ecological Redline
5.1. Principles for Defining the Scope of Space Management and Control
- The principle of consistency with dominant function and restoration goals.
- The principle of coordination with territorial spatial planning.
- The principle of adaptation to local conditions.
5.2. Thinking on the Determination of the River Ecological Corridor Management and Control Scope
5.3. Limitations and Future Research
- As an important vegetation buffer zone, wildlife migration zone, biodiversity protection zone, and also as the minimum boundary in the delineation of the river ecological corridor, the transition zone of the highland edge has important research significance. Its reasonable width range needs to be studied in depth with scientific, comprehensive, and specific methods.
- For the delineation of the ecological protection redline and aquatic ecological redline, feasible management measures and scientific demarcation methods are very necessary. The current research is not in-depth, and the delineation needs further research and exploration to truly ensure the sustainable service function of the water ecosystem.
- What are the river ecological corridor? What functions does it include?
- What is the territorial spatial control line? What is the relationship between it and the river ecological corridor?
- How to define the spatial scope of the river ecological corridor? How can the research on the management and control scope of the river ecological corridor space be carried out scientifically and reasonably?

|2019||Federal Register||Redefine the waters, terminate the jurisdiction of the “transient” rivers, and emphasize the impact of hydraulic engineering on the ecology .|
|China||2021||The 14th Five-Year Plan for Water Security Guarantee||The management of river and lake space should be strengthened to promote the protection and restoration of river shorelines, and the construction of the ecological corridor .|
|2021||The Yangtze River Protection Law||The protection of the Yangtze River Basin must be strengthened, and the protection plan for river and lake shorelines must also be formulated .|
|Germany||2009 (Amended in 2013)||The General Provisions of Water Law||In order to protect water sources from adverse effects, water protection areas should be determined, flood areas should be protected, and natural landscapes should be maintained and regained .|
|2018||Urban Nature Master Plan- Federal Government’s “Vibrant City” Action Plan||The water body and its flood plains are protected to maintain water quality and habitat. Creating a more tranquil and healthy environment to improve the quality of life .|

|Related Concepts||Foundation||Relationship with the Scope of the River Ecological Corridor|
|Urban blue line||Administrative Measures for Urban Blue Line||The blue line is structurally included in the scope of the river shoreline and is the reference line when delimiting the scope of the river ecological corridor.|
|The riparian ecological blue line||Local laws and regulations|
|Urban green line||Administrative Measures for Urban Green Line||In terms of structure, the green line is much larger than the river shoreline. It contributes less to the territorial spatial control line such as the aquatic ecological redline. But it still needs to be used as a reference line to delimit the scope of the river ecological corridor when necessary.|
