摘　　要：为使广大治黄工作者更好地了解黄河流域河流与湖泊普查的情况,介绍了河湖普查的内容、技术路线以及河湖普查的主要地理特征信息,包括标准以上河湖数量及河湖名录,最新的黄河集水面积(813 122 km2)、河长(5 687 km)、河源和河口位置、标准以上河湖以及水文测站的地理水文特征值等。同时,对一些关键的地理特征提出了新的认识和界定。在此基础上,对新成果和原特征值进行了对比分析。In order to make better understanding of basic characteristics of river and lake survey situation of the Yellow River basin to the governance of the Yellow River , the target and technical route were introduced in this paper , and statistical analysis was done on the main ge-ographical feature information of river and lake of the Yellow River basin which was extracted by multi-source data method from advanced 3S technology. This geographical feature information include the number and list of lakes and rivers which above standard , the latest watershed area ( 813 122 km^2 ), length ( 5 687 km ), and estuarine position of the Yellow River , the geographical hydrological eigenvalue of the river and lake and hydrological stations which above standard and so on. The innovation point was that new understanding and definition of the key characteristics of the river and lake were done. On this basis , the new results were compared with the original eigenvalue , and the differences and the reasons were found out.
