环境监测五十载 美丽陕西有我在 ——陕西生态环境监测50年发展纪实

Core Viewpoint - The development of ecological environment monitoring in Shaanxi Province over the past 50 years has transformed from basic manual methods to a sophisticated, integrated monitoring network that utilizes advanced technology and data analysis to ensure environmental protection and improvement [5][9][27]. Group 1: Historical Development - The Shaanxi Provincial Environmental Protection Monitoring Station was established in 1975, starting with over 40 personnel and basic equipment, evolving into a comprehensive monitoring network covering the entire province [5][9]. - By 2024, the province has developed a three-tiered ecological environment monitoring system with 116 monitoring institutions and a workforce of 2,254, equipped with 11,100 advanced instruments [9][12]. Group 2: Technological Advancements - The monitoring capabilities have expanded from basic parameters like pH and dissolved oxygen to 1,320 parameters across 11 categories, including water, air, soil, and noise [9][17]. - The establishment of a "super station" in 2017 equipped with over 30 advanced monitoring devices has strengthened the data foundation for air quality monitoring [16][14]. Group 3: Environmental Achievements - As of 2024, all 46 national control sections of water quality in the Yangtze River Basin within Shaanxi meet Class II standards, with 8 sections achieving Class I [18]. - The PM2.5 concentration in Shaanxi decreased from 51 µg/m³ in 2016 to 35 µg/m³ in 2024, a reduction of 31.3%, with the number of good air quality days increasing from 270.5 to 294.6 [25][26]. Group 4: Future Outlook - By 2035, Shaanxi aims to establish an "Ecological Environment Monitoring Brain" for intelligent pollution tracing, risk warning, and assessment [30]. - The province plans to leverage new technologies such as artificial intelligence and blockchain to enhance ecological monitoring capabilities [27].
