晋祠难老泉复涌！太原多措并举推动地下水超采治理

Core Viewpoint - The revival of the Nandao Spring in Taiyuan, Shanxi Province, is a significant ecological restoration achievement after years of environmental degradation caused by industrial activities and excessive groundwater extraction [1][4][6]. Group 1: Historical Context - The Nandao Spring, known as "the first spring of Sanjin," dried up in 1994 due to large-scale coal mining and industrial water extraction, leading to a continuous decline in groundwater levels [2][4]. - In the 1980s, the spring provided water for over 30,000 acres of farmland and local industries, but its water supply diminished due to environmental damage from mining activities [2][4]. Group 2: Restoration Efforts - From 2006 to 2014, Taiyuan undertook a large-scale consolidation of coal mines, reducing the number of mines from 275 to 53, which significantly decreased the water discharge from mining operations [4][5]. - The city implemented 15 concentrated water source replacement and ecological replenishment projects, reducing groundwater extraction from 451 million cubic meters 20 years ago to an expected 185 million cubic meters by 2024 [5][8]. - In 2023, the Nandao Spring naturally flowed for the first time in years, with a total of 133 days of flow, marking a new high in water levels [6][7]. Group 3: Future Plans - The local government aims to restore the ecological balance by controlling groundwater extraction and limiting high-water-consuming projects within the spring's protection area [7][8]. - Plans are in place to further reduce groundwater extraction by an additional 80 million cubic meters by 2025, aiming for a balance between groundwater extraction and replenishment [8].
