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
Core Viewpoint - The recent extreme weather events, particularly the flash floods in Inner Mongolia, highlight the urgent need for a robust disaster prevention system in the face of increasing rainfall and flooding in traditionally arid northern regions [1][2]. Group 1: Flood Risk Characteristics - Northern cities are experiencing unprecedented rainfall, which, while appearing abnormal, aligns with historical hydrological cycles, indicating a shift from drought to a period of increased precipitation since 2012 [2]. - The distribution of this year's rainfall has been more regional and scattered, affecting areas that are not adequately covered by existing flood prevention measures [2][3]. Group 2: Flood Prevention Strategies - The concept of "giving way to water" is emphasized, suggesting the construction of sunken parks and artificial lakes to serve as temporary flood retention areas during extreme weather events [1][4]. - A call for enhanced public education on flood risks and disaster preparedness is made to improve societal awareness and response capabilities [1][4]. Group 3: Evolution of Flood Management - The flood management system in China has evolved significantly since the 1998 Yangtze River floods, with a focus on large rivers initially, followed by attention to smaller rivers and urban flood management in recent years [4][5]. - The "sponge city" concept has been developed to integrate urban water management systems, but it is acknowledged that it has limitations in extreme weather scenarios [5][6]. Group 4: Infrastructure and Standards - Current urban flood prevention standards are fragmented across different departments, leading to inconsistencies in flood management strategies [7][8]. - The reduction of natural water retention areas due to urban development has exacerbated flood risks, necessitating a reevaluation of urban planning and flood management practices [7][8]. Group 5: Community Involvement and Awareness - Public participation in flood prevention, such as clearing drainage systems and preparing emergency supplies, is crucial for mitigating small-scale flooding [12][13]. - There is a need for increased public awareness regarding flood risks, particularly in northern regions where such events are less frequent, to prevent tragedies like the recent flash flood incident [12][13][14].

Core Viewpoint - The article discusses the increasing frequency of extreme weather events, particularly heavy rainfall in northern China, and emphasizes the need for a more effective flood prevention system that incorporates the concept of "giving way to water" [1][3]. Group 1: Flood Prevention Strategies - Xu Zongxue suggests creating sunken parks, green spaces, and artificial lakes as temporary flood retention areas during extreme rainfall events [3]. - The article highlights the importance of enhancing public education on flood prevention and risk awareness to improve societal preparedness for flood disasters [3][35]. Group 2: Characteristics of Recent Flooding - Northern cities are experiencing unprecedented heavy rainfall, which is characterized by its widespread and irregular occurrence, differing from past patterns [5][6]. - The areas most affected by flooding are often those that have not been adequately addressed by existing flood prevention systems, indicating weaknesses in current infrastructure [6]. Group 3: Historical Context and Evolution of Flood Management - Since the 1998 Yangtze River floods, significant investments have been made in flood management, focusing initially on major rivers and later shifting towards smaller river systems [8][9]. - The concept of "sponge cities" was introduced post-2012 to enhance urban flood management capabilities, integrating various urban water systems [10][13]. Group 4: Urban Planning and Infrastructure - Urban planning must consider regional differences in climate and hydrology, with tailored solutions for northern and southern cities [17][18]. - The article advocates for restoring natural water retention areas that have been lost due to urban development, which is crucial for improving flood resilience [22][23]. Group 5: Public Awareness and Community Involvement - The article stresses the need for increased public awareness regarding flood risks, particularly in areas that have historically been considered safe [7][36]. - Community efforts, such as clearing drainage systems and preparing emergency supplies, can significantly mitigate the impact of flooding [34][37]. Group 6: Limitations of Current Flood Management Approaches - The article points out that current flood management standards are inconsistent across different departments, leading to potential vulnerabilities in urban flood defenses [22]. - It emphasizes that while "sponge cities" can manage typical rainfall, they are not sufficient for extreme weather events, necessitating emergency response plans [14][38].
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· 2025-08-23 05:24
Core Viewpoint - The recent tragic event in Inner Mongolia highlights the urgent need to improve disaster prevention systems in the face of extreme weather, particularly in northern regions that are traditionally less prone to heavy rainfall [1][2]. Group 1: Flood Prevention Strategies - Xu Zongxue emphasizes the importance of creating temporary flood retention areas through urban renewal and village renovations, such as sunken parks and artificial lakes, to manage extreme rainfall [2][3]. - The current flood prevention system in northern cities has significant weaknesses, particularly in areas not covered by major river protections or sponge city initiatives [3][4]. Group 2: Historical Context and Evolution of Flood Management - Since the 1998 Yangtze River flood, China has invested heavily in flood management, focusing initially on major rivers and later shifting to smaller river systems over the past decade [5][7]. - The concept of sponge cities has evolved to integrate urban water management systems, addressing both common rainfall and extreme flooding events [11][12]. Group 3: Public Awareness and Preparedness - Public education on flood risks and safety measures is crucial, especially in light of recent tragedies caused by flooding in areas where people underestimated the risks [22][23]. - Community efforts, such as clearing drainage systems and preparing emergency supplies, can significantly mitigate the impact of minor flooding events [22][23]. Group 4: Technical and Infrastructure Recommendations - There is a need for a unified standard for flood management across different governmental departments to improve coordination and effectiveness [17][18]. - Enhancing urban drainage capacity, increasing floodwater retention areas, and utilizing green infrastructure are essential strategies for improving urban resilience against flooding [19][20].
从“热岛”到“雨岛” 专家解读“晚高峰”为何频遇阵雨
Xin Lang Cai Jing· 2025-08-22 03:44
Core Viewpoint - The increase in urban rainfall during peak hours is attributed to the "rain island effect," which is a consequence of the "heat island effect" in cities [2][3]. Group 1: Urban Climate Effects - The "heat island effect" refers to urban centers being significantly warmer than surrounding rural areas, with temperature differences of 2°C-3°C due to artificial structures and reduced green spaces [2]. - The "rain island effect" is formed as urban pollutants create condensation nuclei that lead to cloud formation, resulting in increased rainfall in urban areas [2][3]. Group 2: Urbanization and Flooding - Rapid urbanization has transformed agricultural land into urban areas, increasing impervious surfaces and reducing water absorption, which exacerbates flooding during heavy rainfall [3]. - Climate change is also a significant factor contributing to extreme weather events, including urban flooding [3]. Group 3: Urban Flood Management Strategies - The concept of "sponge cities" aims to enhance urban resilience to environmental changes and natural disasters by improving rainwater absorption and management [3][4]. - The "big sponge" approach emphasizes integrated flood management at the watershed level, considering urban areas alongside surrounding natural ecosystems [4]. - The Chinese government has initiated policies to strengthen urban flood management, focusing on source reduction, drainage systems, and emergency responses [4].
