摘要: 开展长江沿线城市水生态环境跟踪驻点研究,是贯彻习近平总书记“长江大保护”重要指示精神的具体体现。以长江中游城市九江市全域为研究区域,在资料收集和实地调研的基础上,运用信息化手段,采用统计分析、数值模拟等研究方法,开展了以数据库构建、驻点研究平台建设、水生态环境问题诊断、污染物溯源剖析、综合解决方案制定为主要内容的系统研究,探索了驻点城市需求与长江生态环境保护联合研究任务相互嵌套的研究思路,摸索出一条“数据平台构建→全域问题诊断→逐层双向剖析→全过程综合施策”的城市水环境问题“把脉、问诊、开药方”技术路线和方法体系,提出了一套统筹“结构减排、技术减排、管理减排”3个维度,遵循“源头预防、过程控制、末端治理”的全过程管治的“一市一策”综合解决方案,以期为拥有复杂水生态环境的城市开展同类型研究提供借鉴。Abstract: Carrying out tracking station research on water ecological environment in cities along the Yangtze River is a concrete manifestation of implementing the spirit of President Xi Jinping′s important instructions on "Great Protection of the Yangtze River". The whole area of Jiujiang City, a city in the middle reaches of the Yangtze River was taken as the research area. On the basis of data collection and field research, and applying information technology, statistical analysis, numerical simulation and other research methods, a systematic research was conducted mainly on database construction, station research platform construction, water ecological environment problem diagnosis, pollutant traceability analysis, and comprehensive scheme formulation. The research ideas of the mutual nesting of the demands of the stagnation city and the joint research tasks of the Yangtze River ecological environment protection were explored. The technical route and the method system of "data platform construction → global problem diagnosis → layer-by-layer two-way analysis → comprehensive policy implementation in the whole-process" for "pulse examination, inquiry, and prescription" for urban water environment problems was established. A set of comprehensive solutions of "one city, one policy" that coordinated the three dimensions of "structural emission reduction, technical emission reduction, and management emission reduction" and followed the whole-process governance of "source prevention, process control, and end management" were proposed. The research could provide reference for the same type of research in cities with complex water ecological environment.
