Reviewer #2: The paper presented the history, thoughts, methods and practice of eco-river construction of China. The authors emphasized the importance of ecosystem construction and local social and cultural heritage. However, the reviewer thought it a little too simple in the thoughts and design of eco-river the authors discussed in the paper. The paper discussed the function of eco-rivers on living things, human, traditional culture, environmental education and public participation, did the eco-river only have these functions? What about the other functions such as impacts on landscapes, urban form, climate? And how the authors define eco-culture river and eco-river? Are there any published works on these?
1. From the Section of Introduction, I expected to read the published works on eco-culture river or eco-river construction and theory, but there were only the history of China's river development. How about the thoughts and designs of other countries or areas?
2. There is no specific definition for eco-culture river, which made it hard to evaluate how we can do to improve the river functions to achieve eco-culture river?
3. The paper is talking about China's river, Why did the authors add some successful river construction or design of developed countries for comparison? The figures used in the paper were difficult for us to say it is good for an eco-culture river, other successful figures for eco-river of other areas are suggested.
4. The theory of eco-culture river in this paper is too simple.
