Core Viewpoint - The Ministry of Ecology and Environment has announced the third batch of 43 ecological quality comprehensive monitoring stations, contributing to a total of 214 stations across three batches, aimed at establishing a "sky-ground integrated" monitoring system for ecological quality [1][2]. Group 1: Monitoring Stations Overview - The ecological quality comprehensive monitoring stations are essential components of the "sky-ground integrated" ecological quality monitoring system, designed to support ecological protection and restoration through long-term monitoring and data accumulation [2]. - The first batch included 55 stations, with 33 led by the Ministry of Ecology and Environment, 17 by the Chinese Academy of Sciences, and 5 by other entities, covering major ecosystem types such as forests, wetlands, grasslands, deserts, oceans, cities, and farmland [2]. - The second batch consisted of 116 stations, bringing the total to 214 stations across the first three batches [2]. Group 2: Monitoring Content - The monitoring content of the ecological stations includes eight major categories: atmospheric environment (e.g., SO₂, PM 2.5), soil physicochemical indicators, vegetation growth parameters (e.g., leaf area index, NDVI), wildlife populations, hydrological water quality (e.g., turbidity, flow rate), and greenhouse gas flux [3].
