计算机技术在水库原始地形及库容采集中的应用

Computer data acquisition for the Xiaolangdi reservoir

黄河小浪底水库设计阶段使用的原始库容是依据 196 6年航测的 1:1万地形图 ,利用求积仪人工量算的 ,距今已 30余年。为了满足水库运用方式研究的需要 ,黄委会设计院于 1995年 5月航测了水库 1:1万地形图。本次以该地形图为基础 ,利用先进的计算机技术对水库的原始地形、库容及分布进行了采集 ,取得了满意的成果。

The original storage capacity of the Xiaolangdi reservoir was artificially calculated with a planometer as per the topographic map (Scale 1:10000) aerial surveyed more than 30 years ago in 1966. For research of operation mode of the reservoir, the aerial topographic map was surveyed once again by the Yellow River Design Institute in 1995. Data of the original topography and storage capacity as well as their distribution are collected on the basis of the map by adopting the advanced computer technology.
