黄河与开封关系密切。建炎二年(1128)后渐次南泛的黄河,再造了开封城及附近的地理景观。系统梳理了金代黄河下游上段河道的变迁情况,指出大定十一年(1171)黄河开始影响开封。黄河决溢南泛使开封紧邻险工、广济河淤废和东明、胙城、长垣政区改隶。金代黄河未决入开封城内,城市发展取决于金宋之间的军事形势和城市地位的升降,故黄河对开封无直接影响,但始终是城市的重要防御线。
Yellow River is closely related to Kaifeng. Its southward course changes since 2nd year of Jianyan Reign (1128) reshaped systematic survey of the course c the geographical landscapes of hanges of upper-reach Yellow Kaifeng River in the River began to influence Kaifeng in the 11th year of Dading Reign City and adjacent areas. Based on Jin Kingdom, it is pointed out that (1171) . Flooding of Yellow River endangered Kaifeng City, silted Guangji River and changed the administrative segmentation of Dongming, Zuocheng and Changyuan region.
