抗战时期黄河南泛与豫东黄泛区生态环境的变迁

The Yellow River's Flooding toward South during the Anti-Japanese War Period and Ecological Environment Changes of the Flooded Area in East Henan

花园口决堤而形成的黄泛区问题,是抗日战争时期的重要社会问题之一。由于黄河南泛,导致豫东泛区生态环境发生巨大变化。首先,土壤的沙化、盐碱化彻底改变原有的地理环境,形成特殊的地貌特征;其次,广阔土地被水淹没,农业生产严重破坏,各种生态灾害频发,导致农作物减产加剧;最后,河水摧毁房屋和村落,破坏防洪排涝和灌溉系统,人居环境持续恶化,导致人口大量死亡与逃离家园。上述三者之间相互影响、相互关联,对当地生态环境产生了深远的消极影响。

The Yellow River＇s flooding toward south as a result of dyke breaching at Huayuankou during the Anti-Japanese War period lead to changes of soils and land features,destruction of agricultural production and deterioration of dwelling environment.The foregoing three aspects interacted and correlated,thereby having lasting and profound negative effects on the local ecological environment.
