Core Viewpoint - The successful inclusion of the Shiyan River (Shiyan Reservoir) in Shenzhen into the fourth batch of beautiful rivers and lakes by the Ministry of Ecology and Environment highlights the city's innovative "city-water symbiosis" governance model, which has gained national recognition and serves as a replicable model for similar urban reservoirs [2][3]. Group 1: Urban Challenges - The Shiyan Reservoir, built in 1960 with a capacity of 31.98 million cubic meters, is the second-largest water supply reservoir in Shenzhen, providing an annual average of 360 million cubic meters of water [3]. - As urban development rapidly expanded, the reservoir became surrounded by dense construction, leading to challenges such as water resource shortages and unstable water quality from tributaries [3]. Group 2: Governance Solutions - Shenzhen implemented a systematic approach to governance, establishing a 108.02 square kilometer water source protection area and constructing over 105 kilometers of isolation fencing [4]. - The city executed a significant "one water demolition" campaign, removing 310,000 square meters of illegal constructions within the primary water source protection area in just eight months, a model now promoted nationwide [4]. Group 3: Technological Empowerment - A comprehensive monitoring network was established at the Shiyan Reservoir, including 35 automatic water quality monitoring stations and 11 AI ecological monitoring devices to detect illegal activities [5]. - The management team, consisting of nearly 100 personnel, ensures effective ground inspections to address issues promptly [5]. Group 4: Ecological Benefits - The water quality of the Shiyan Reservoir has improved to a stable level of Class II surface water, with an increased annual water supply capacity of 500 million cubic meters [6]. - The ecological restoration has led to a high natural ecological shoreline rate of 89.1% and a vegetation coverage of 91.4% in the buffer zone, supporting over 500 species of flora and fauna [7]. Group 5: Economic Transformation - The ecological improvements have transformed the Shiyan Reservoir into a "green engine" for high-quality regional development, enhancing both ecological and economic benefits [8]. - The area has attracted high-end talent and industries, with over 130,000 various talents introduced, showcasing the strong appeal of a livable ecological environment [8]. Group 6: Sustainable Development Model - The governance practices at Shiyan Reservoir provide a systematic model for managing urban reservoirs, emphasizing fine governance over large-scale demolition and promoting sustainable mechanisms instead of short-term fixes [9].
