China Economic Weekly | Water Environment Management of Guiyang Nanming River and Dali Erhai Lake Selected as the Opening Cases of “Dialogue with Leading Cadres on Ecological Progress“

2022-03-07

On the occasion of the annual parliamentary meeting (China’s LiangHui) in 2022, a book named "Dialogue with Leading Cadres on Ecological Progress" as the research findings of the projects conducted by the CPC Central Committee, was published by the Central Party School Publisher. This book focuses on the nationwide ecological progress with exploration for realizing the values of ecological products. Six typical regional cases have been fully interpreted, among which "DURWEcosystems on Ensuring Urban Ecological Progress" conducted by CWEG (China Water Environment Group) was successfully selected as one of the openings. The problems and challenges faced in the process of controlling water pollution and paths and mechanisms for realizing values of ecological products are listed in this book. An innovative technology system and management pattern in this regard has also been introduced, which provides innovative experience and practices on improving ecological product values.


According to Professor Li Hongwei, the chief editor of the book, also director of the Teaching and Research Section on Ecological Progress of the Central Party School, establishing and perfecting mechanisms for realizing values of ecological products is a key measure to practice the ideology of ecological progress and to fulfill the idea that clear waters and green mountains are invaluable assets. It is also of vital importance to the overall transformation of society and economy into green ones.

The Before and After Management Situation of Nanming River


Employed by the CWEG, methods of "Distributed Underground + Mother River Management" applied to Nanming River and "Distributed Underground + Lake Management" to the Erhai Lake were selected as the opening cases in the book. Dr. HouFeng, the chairman of China Water Environment Group, said that the DURWecosystem has changed the ways of how the world dealing with water sewage for centuries. Instead of discharging the urban sewage as pollutants, we use it as a stable resource for urban water recycling and we dedicated in its scientific collection and resource utilization. This ecosystem was originated from Nanming River and first put to use for the water management here too. 16 underground WWTPs have been built along the bank of Nanming River with 5 of them are upgraded. Moreover, the river ecological restoration and landscaping covers 120 kilometers. The Guiyang Nanming River management has achieved "Three Firsts". It’s the world’s first engineering practice of DURWecosystems and the plant-river-lake integration mode within cities. It is the first water management pattern to change the water management divided by sections. Through overall planning and step-by-step implementation, this system has ensured the realization of the govern goal for a green city with clear waters and green landscape and where all the creatures can live harmoniously together. It will also be the first city in China to achieve carbon neutrality in the near future.

Guiyang Nanming River After Management


"The DURWecosystem is a great example for cities in China, especially for those large and medium-sized cities with large population, scarcity of land but at the same time, with black-smelly rivers lack of clean waters. And it plays a vital role in promoting the value of urban ecological products. This system has been used by 22 regions for reference in China, such as Beijing and Shanghai. It further provides countries lacking land and water across the world a solution based on the experience of China." Dr. Houfeng told us.

        During the 14th Five-Year Plan period (2021-2025), two documents were issued, and they were the Opinions on Establishing and Perfecting Ecological Progress System, and the Opinions on Advancing Ecological Conservation Compensation Revolution. After that, all regions in the country have started to explore the pathways to realize the values of ecological products. Against the backdrop of the 14th Five-Year Plan period, this book, with an in-depth interpretation and analysis of typical cases, presents us the theoretical and practical proposition for realizing the values of ecological products based on the concept of "clear waters and green mountains are invaluable assets". This proposition provides experiences for leading cadres in China to push forward the realization of ecological values and further the progress of turning clear waters and green mountains into invaluable assets.
