摘　　要：从1986-1999年,沿河南省水系、河流及道路布设了数百条各等级水准线路,把河南省的水利高程系统统一归算到国家现行1985国家高程基准上。文章简单介绍了河南省高程系统在河南省各水利工程建设中所发挥的重要作用及标石破坏的现状,并对复测的必要性和重要性等工作提出了建议。From 1986 to 1999,hundreds of leveling lines of various levels were laid out along the water system,rivers,and roads of Henan Province,and the water conservancy elevation system of Henan Province was unified and calculated on the current 1985 national elevation benchmark.The article briefly introduces the important role played by the elevation system in the construction of various water conservancy projects in Henan Province,as well as the current situation of stone damage,and puts forward work suggestions on the necessity and importance of retesting.
