以金融担当筑牢秋粮丰收基石
Zheng Quan Ri Bao· 2025-08-24 14:26
近日,财政部会同农业农村部下达中央财政农业生产防灾救灾资金11.46亿元,支持13个粮食主产省份 实施秋粮"一喷多促",全力做好防灾减灾促稳产工作。 这一举措彰显了国家对于秋粮生产的高度重视,为稳定秋粮生产、全年粮食丰收提供有力保障。在这一 过程中,银行作为金融服务实体经济的关键力量,同样肩负着重要使命。 秋粮在全年粮食生产中占据大头,其产量关乎国家粮食安全大局。从播种到收获,秋粮生产周期长,面 临诸多不确定性,如自然灾害、病虫害侵袭等,每一个环节都离不开资金支持。银行应充分认识到秋粮 生产的重要性,提前布局,精准配置金融资源,满足秋粮生产各环节的资金需求。 加大信贷支持力度是银行助力秋粮生产的关键举措。一方面,针对广大秋粮种植户,尤其是受前期低 温、干旱、洪涝等灾害影响的地区,银行应迅速行动,推出专项贷款产品。简化审批流程,降低贷款门 槛,以最快速度将资金送到受灾农户手中,帮助他们恢复生产、补种改种,确保农事活动按时推进,不 误农时。另一方面,聚焦秋粮主产区的种粮大户、家庭农场、农民合作社等新型农业经营主体,这些主 体规模化程度高,对资金的需求更为庞大。银行需深入调研,根据其经营特点、种植规模和资金周转周 ...

Core Viewpoint - The research team from the Chinese Academy of Sciences has made significant advancements in the precise monitoring and accounting of carbon emissions from large coal-fired power plants, which is crucial under the global "dual carbon" goals of peak carbon emissions and carbon neutrality [1][2]. Group 1: Research Breakthroughs - The research team has developed a new satellite remote sensing solution that enables high-precision dynamic quantification and mapping of carbon dioxide emissions from large coal-fired power plants, marking a significant achievement in the field [1]. - The study was published in the international academic journal "Clean Production," highlighting its importance in providing objective and effective technical means for carbon emission accounting and verification [1][2]. Group 2: Methodological Innovations - The team introduced a model optimization algorithm based on the U.S. Orbiting Carbon Observatory-3, significantly improving the efficiency of background carbon emission value identification [2]. - A dynamic wind direction correction algorithm was developed to enhance the accuracy of smoke plume trajectory inversion, along with a smoke plume elevation model that accurately characterizes the dynamic lifting process of flue gas [2]. Group 3: Implications for Carbon Monitoring - The research results indicate that the improved Gaussian plume model successfully quantified carbon dioxide emissions from 14 large coal-fired power plants, with emissions ranging from 21.54 thousand tons to 82.3 thousand tons per day, demonstrating a significant increase in inversion accuracy [2]. - This research signifies a critical shift from static carbon emission inventories to dynamic management, which is essential for effective carbon monitoring and policy calibration [3].
“四农普”来了,将对农业新质生产力等进行调查
