Core Viewpoint - Tianjin has successfully reduced the average ground subsidence in the plain area from 20 millimeters to 1 millimeter through comprehensive groundwater management strategies, including a significant increase in deep groundwater levels and a reduction in extraction volume [1]. Group 1: Groundwater Management Achievements - From 2018 to 2024, the deep groundwater level in Tianjin has risen continuously for six years, with a total increase of 11.8 meters [1]. - The extraction volume of deep groundwater has decreased from 150 million cubic meters to 42 million cubic meters [1]. - The average ground subsidence in the plain area has been reduced to 1 millimeter [1]. Group 2: Water Conservation Initiatives - Various sectors are being promoted to save water, including agriculture, industry, and urban areas, with specific measures to enhance efficiency and reduce waste [2]. - The water consumption per unit of GDP has decreased to 17.75 cubic meters, while the water consumption per unit of industrial added value has dropped to 8.1 cubic meters [2]. - A total of 10.1 thousand deep groundwater wells have been shut down, and management practices have been implemented to prevent illegal water usage [2]. Group 3: Water Source Management - The city has effectively expanded the surface water supply range, converting water sources for 286.8 million rural residents and 35 million acres of farmland [2]. - Annual water source guarantees for agriculture in areas of deep groundwater over-extraction exceed 1 billion cubic meters through various water source management strategies [2]. - The delineation of groundwater prohibition and restriction zones has been reinforced, with no new deep groundwater extraction permitted in these areas [2].

Group 1 - The core viewpoint is that Tianjin has successfully implemented comprehensive measures to manage groundwater over-extraction, resulting in a significant recovery of deep groundwater levels and a reduction in extraction volume [1][2] - From 2018 to 2024, the deep groundwater level in Tianjin has risen continuously for six years, with a total increase of 11.8 meters [1] - The extraction volume of deep groundwater has decreased from 150 million cubic meters to 42 million cubic meters [1] Group 2 - The city has adopted a multi-faceted approach focusing on "saving," "controlling," "adjusting," and "managing" water resources to combat groundwater over-extraction [2] - Various sectors have been encouraged to save water, with the water consumption per unit of GDP reduced to 17.75 cubic meters and the water consumption per unit of industrial added value reduced to 8.1 cubic meters [2] - A total of 10.4 thousand deep groundwater wells have been shut down, and water source conversions have been implemented for 286.8 million rural residents and 1.684 thousand enterprises [2]

Core Viewpoint - The article highlights the successful restoration of spring water in various regions of China due to comprehensive management of groundwater over-extraction, leading to increased tourism and ecological benefits. Group 1: Groundwater Management Efforts - Various regions in China, including the North China Plain and Fenwei Valley, have implemented comprehensive groundwater over-extraction management, resulting in the revival of previously dried springs [1][3]. - The Ministry of Water Resources, in collaboration with other governmental departments, has introduced the "14th Five-Year Plan for Key Areas of Groundwater Over-Extraction Management," targeting specific regions for effective measures [3]. Group 2: Regional Success Stories - In Jinan, the implementation of the "Jinan Spring Protection Regulations" has led to a reduction of approximately 10 million cubic meters per year in groundwater extraction, enhancing the monitoring system with 213 groundwater level monitoring points [2]. - In Taiyuan, the historical Nanao Spring, which had been dry for over 30 years, has seen a resurgence due to ecological restoration efforts, including the closure of over 200 coal mines and 2,000 high-water-consuming enterprises [2]. - The revival of springs in Xingtai, such as the Baquan Yuanshui Park, has attracted numerous tourists, showcasing the integration of spring water ecological value into cultural tourism [2]. Group 3: Positive Outcomes and Future Plans - The water levels in the shallow and deep groundwater in the Beijing-Tianjin-Hebei region are projected to rise by 3.19 meters and 8.46 meters, respectively, by 2024 compared to 2018, indicating significant progress in groundwater management [3]. - The Ministry of Water Resources plans to continue enhancing groundwater over-extraction management efforts and establish long-term protection mechanisms to ensure the sustainability of spring water revival [3].
