北方暴雨频发,多地突发山洪 对话水文专家徐宗学:防洪何以“为水让路”
Mei Ri Jing Ji Xin Wen· 2025-08-26 16:27
近日,内蒙古巴彦淖尔市乌拉特后旗乌盖苏木东乌盖沟突发山洪,致使12名野外露营人员遇难——这一 沉重事件再次将极端天气下的防灾体系推至公众视野。当暴雨频频"光顾"北方、屡次突破防洪标准,是 否忽略了系统性防御中最关键的一环? 针对这个话题,近日,《每日经济新闻》记者(以下简称NBD)专访了国际水文科学协会(IAHS)前 副主席、城市水循环与海绵城市技术北京市重点实验室主任、北京师范大学水科学研究院徐宗学教授。 "在山洪易发的汛期,切勿在行洪区域逗留。"徐宗学提醒道。 面对超标准暴雨洪水,徐宗学认为,根本出路在于"为水让路"。他建议,结合城市更新与城中村改造 等,建设下沉式公园、绿地与人工河湖,将其作为特大暴雨发生时的临时滞洪区。同时,他也呼吁加强 全民防洪避险教育,提升全社会对洪水灾害的敬畏和防范能力。 问诊:传统少雨北方频遭暴雨侵袭,防洪体系短板何在? NBD:近期,北方多地突发特大暴雨,这些地区传统上属于少雨区,但出现了极端降水情况。从您的 观察来看,与过去相比,北方城市面临的暴雨灾害有哪些新特点? 徐宗学:从水文周期规律看,今年北方的暴雨虽然感觉异常,但其实符合水文周期性特征。以北京为 例,从2000年前 ...

Core Viewpoint - Climate extremization has become a norm, with global warming leading to intensified rainfall and drought conditions in specific regions, resulting in sudden shifts between drought and flooding [1][3][8]. Group 1: Extreme Weather Events - Recent years have seen a significant increase in extreme weather events globally, with high temperatures, floods, and storms becoming more frequent and intense [5][6]. - In July, the average temperature in Henan Province reached 30.5°C, 3.2°C higher than the historical average, marking the hottest period in 64 years [2]. - Northern China experienced above-average rainfall, with Inner Mongolia recording the highest precipitation for this period since 1961 [2][3]. Group 2: Impact on Agriculture - Extreme weather is adversely affecting major grain-producing areas in China, with high temperatures and heavy rainfall impacting crop growth and increasing irrigation costs [3][14]. - The growth of winter wheat is particularly vulnerable to insufficient low-temperature periods, which can lead to premature ear formation and reduced yields [15]. - High temperatures can cause corn leaves to curl, affecting photosynthesis and increasing water requirements, thus raising irrigation costs for farmers [15]. Group 3: Future Projections and Preparedness - The ongoing climate crisis requires urgent action, with a need for five times the current effort to effectively address climate challenges [11]. - Transitioning to green renewable energy is essential, despite the associated costs, as it presents significant industrial opportunities while mitigating future disaster losses [11]. - The upcoming weather patterns indicate that northern regions may continue to face flooding, while southern areas will experience heightened drought conditions [12]. Group 4: Economic Implications - The volatility of agricultural prices due to extreme weather events is expected to persist, with "weather-related price hikes" becoming more common [16]. - Developing countries may be disproportionately affected by extreme climate events, leading to potential resource conflicts and social instability [17]. - Industries related to agriculture may need to adapt their insurance models and financial tools to better manage the risks associated with climate change [18]. Group 5: Urban Planning and Infrastructure - The concept of sponge cities is being emphasized, but their capacity to handle extreme rainfall is limited, necessitating additional strategies for flood management [19][20]. - Urban planning must evolve to incorporate designs that can effectively manage high temperatures and heavy rainfall, ensuring resilience against climate impacts [18][20].
