Core Viewpoint - The implementation of ecological environment zoning and control aims to safeguard regional ecological functions and improve environmental quality through differentiated and precise management [1][2] Group 1: Ecological Environment Zoning and Control System - Jiangsu has divided its land and sea into 4,570 control units, with 4,268 on land and 302 at sea, each equipped with an "ecological environment access list" that specifies entry requirements and regulates development activities [1] - The "Jiangsu Provincial Ecological Environment Zoning and Control Comprehensive Service" platform has been established to support this system, integrating vector data from all control units and facilitating data sharing across various levels of government [1] - The platform has over 6,700 registered users, with a total of 133,000 visits and 29,000 analysis reports generated, providing public services such as environmental feasibility analysis for site selection [1] Group 2: Impact of Zoning and Control Implementation - Since the introduction of the "Three Lines and One List" ecological environment zoning and control scheme in 2020, the system has optimized the site selection of 102 linear projects, avoiding national ecological protection red lines and provincial ecological space control areas [2] - The initiative has protected 202 important ecological spaces and has either blocked or optimized 281 projects in industries such as chemicals, metallurgy, and electroplating, effectively preventing ecological damage at the source [2]

Core Viewpoint - The ecological environment zoning and control system in Jiangsu Province is a significant innovation in ecological civilization construction, aimed at implementing differentiated and precise management by region, thereby establishing clear boundaries for development and protection [1][3]. Group 1: Implementation and Progress - Since the implementation of the ecological environment zoning and control system, Jiangsu has optimized the site selection for 102 linear projects, actively avoiding national ecological protection red lines and provincial ecological space control areas, thus protecting 202 important ecological spaces [1][3]. - The Jiangsu Provincial Environmental Protection Department has established a comprehensive service platform for ecological environment zoning and control, aiming for clear management rules and easy access to policy documents and services for enterprises [3]. Group 2: Environmental Quality Improvement - The ecological environment quality in Jiangsu has significantly improved since the implementation of the zoning control system, with the annual average water quality of national monitoring sections reaching excellent levels for three consecutive years [4]. - As of January to August 2025, 92.4% of national monitoring sections' water quality met or exceeded Class III standards, and the overall water quality of the Yangtze River and the Grand Canal in Jiangsu is rated as excellent [4]. - The average concentration of PM2.5 has met the secondary air quality standard for four consecutive years, indicating a steady improvement in air quality [4].
