摘要
在追寻黄河面积和河长的历史沿革时发现,黄河有历史记载以来的2 000多a间,很难找到黄河面积和河长等特征数据。通过查阅清朝至中华民国的相关资料,参考黄河的历史变迁,发现由于黄河的水系、流域边界经常变化,加之当时测量技术的限制,因此黄河流域面积、河长等特征概念和特征数据到了中华民国时期才开始出现。介绍了新中国成立后几个时期的黄河集水面积和河长特征值的历史沿革情况,最新的河湖普查结果表明:黄河流域集水面积约为813 122 km~2,黄河干流河长约5 687 km;黄河流域面积大于50 km~2的河流有4 157条,水面面积大于1 km~2的湖泊有146个。
When looking for the area and length of the Yellow River,it was difficult to find theeigenvalue such as area and length of the Yellow River during more than 2,000 years since the Yellow River was recorded in history. By consulting relevant information of more than one hundred years since the late Qing Dynasty,we found that the latest characteristics concept and data such as length of the Yellow River began to appear in the recent period of the republic of China because of the frequent change of Yellow River water system and basin boundary,combined with the limitation of measurement technology. The paper introduced the history of the eigenvalue such as watershed area and the length of the Yellow River in detail. The latest river and lake survey results show that the catchment area and the length of the Yellow River are about 813,122 km~2 and 5,687 km respectively. There are 4,157 rivers with an area of more than 50 km~2 and 146 lakes with an area of more than 1 km~2 in the Yellow River basin.
