面对此次污染过程，四川建立高效应对机制。每日召开全省重污染天气应急响应会商会，动态筛查、派 发异常问题线索，督促各地及时反馈处置情况，形成闭环管理。针对问题突出、整改不力的个别城市， 四川省生态环境厅直接派出现场核查组，必要时统筹力量开展集中攻坚，确保应急响应措施落地见效。 全省各地市州迅速响应，结合自身实际打出精准管控"组合拳"。成都市调动VOCs走航监测车排查高值 区域，联合公安部门开展柴油货车路检路查，加大重点区域道路洒水降尘力度；自贡市成立7个专项工 作组，落实24小时"人盯数"专报制度，通过无人机排查、走航车雷达扫描强化监测溯源，同步开展移动 源监管与夜间降尘作业；广元、乐山等地聚焦重点排污企业、施工工地，督促落实减排及扬尘管控措 施，联合多部门管控高污染车辆；宜宾由市委市政府相关负责人带队督导，组建夜查小组严防秸秆焚烧 等问题；眉山、资阳等地则通过现场督导帮扶，推动企业优化生产流程、提升治污设施效能，从源头削 减污染。 成都12月23日消息 近日，记者从四川省生态环境厅了解到，四川省遭遇一轮颗粒物污染过程，全省上 下统筹联动、协同作战，通过狠抓工业减排、扬尘管控等一系列举措强化污染源头治理，成功实 ...

Core Viewpoint - The newly issued "Regulations on Ecological Environment Protection Supervision" emphasizes the importance of rectification work to address identified issues, ensuring a closed-loop process in environmental governance [1][2]. Group 1: Rectification Process - The regulations require entities under supervision to develop rectification plans that specify responsible parties, goals, timelines, key measures, and verification units for each identified issue [1]. - Rectification is categorized into three types based on complexity: immediate rectification for simple issues, structured long-term plans for complex issues, and comprehensive strategies for historical problems [2][3]. Group 2: Types of Issues - Simple issues are expected to be resolved quickly, with local governments mobilizing resources to achieve satisfactory outcomes for the public [2]. - Complex issues often involve significant investment and technical challenges, necessitating a resilient approach and continuous optimization of solutions to minimize pollution at the lowest cost [3]. - Historical issues present significant challenges due to their complex backgrounds, requiring careful management and a gradual approach to achieve compliance with environmental standards [4]. Group 3: Case Studies - A case involving a town with multiple stone processing enterprises highlighted the need for a balanced approach, combining shutdowns and upgrades to address noise and air pollution effectively [3]. - In another instance, a long-standing antimony pollution issue in a mountainous area required a phased strategy to manage both point and non-point source pollution while considering the operational viability of local mining enterprises [4].

Core Viewpoint - The contributions of ecological and environmental scientists are essential for the protection and improvement of the environment, yet they often remain unrecognized and underappreciated in society [1][2][5]. Group 1: Contributions and Recognition - Ecological and environmental scientists play a crucial role in pollution control, ecological restoration, and the development of policies that support a beautiful China [1][5]. - Their work is often characterized by teamwork and systemic engineering rather than individual breakthroughs, making it difficult for the public to recognize their contributions [1][2]. - The efforts of these scientists are vital for achieving green and high-quality economic development, as they provide the necessary technological support for environmental governance [2][5]. Group 2: Challenges and Support - The perception of environmental protection as merely institutional constraints overlooks the significant role of ecological science in addressing environmental issues [2][3]. - Continuous innovation and exploration are required to tackle evolving environmental challenges, necessitating support for both advanced and exploratory research [3][4]. - There is a need to support both young, innovative researchers and experienced scientists, including retired professionals who continue to contribute to environmental protection [3][4]. Group 3: Legacy and Cultural Significance - The spirit of ecological and environmental scientists is characterized by a commitment to knowledge production and social practice, which is essential for addressing environmental justice and public understanding [4]. - There is a lack of comprehensive documentation of the contributions and stories of these scientists, with only a few published biographies in the field [4]. - Systematic efforts are needed to document and share the narratives of ecological scientists to build a foundation of confidence in ecological science [4].
