Due to continuous damage to vegetation and excessive development in history, the ecological environment has been seriously damaged. In this paper, historical literature and geographic information system technology were used to investigate the ecological environment in the Huangfanyu area from 1938 to 1947. The study found that the ecological environment in the Huangfanyu area was poor, with dense water grass on the surface, sparse green vegetation, serious soil erosion, and severe water pollution. In addition, there is a large-scale desertification in northern China. The results of this study can provide a reference for environmental protection and ecological restoration in the Huangfanyu area.【Keywords】Huangfanyu area; ecological environment; soil erosion; water pollution; desertification in northern China【引言】豫东黄泛区是我国北方典型的黄淤土区，也是我国曾经的“九省通衢”之一，其生态环境历来备受关注。然而由于长期的过度开发和不当利用，豫东黄泛区的生态环境受到了严重的破坏，影响到了当地百姓的生产生活。为了解豫东黄泛区生态环境的变化，本文利用历史文献资料及地理信息系统技术，对该区 1938 年至 1947 年的生态环境进行初步探究。【讨论方法】本文采纳文献资料法和地理信息系统技术相结合的方法，对豫东黄泛区 1938 年至19...
