本文简介南宁地区几个“区域代表站”受水利工程影响的概况,提出受水利水电工程影响的水文站要收集有关资料,验证原水文分区,确定设站目的。这类站的测验工作,强调点面兼顾,实测与调查相结合;特别是水库配套观测要加强。对资料还原方法作初步探索并提供了阶段成果。这些成果表明:水库调蓄对洪水资料影响明显,跨流域引水和灌溉用水则对月年径流影响显著。并对站网调整问题提出雏议。
This article describes the situation of several “regional representative stations” in Nanning affected by water conservancy projects. It is proposed that hydrological stations affected by water conservancy and hydropower projects should collect relevant data, verify the original hydrological subarea and determine the purpose of setting up stations. The test work of this type of station emphasizes point-to-point combination of actual measurement and investigation; in particular, supporting observation of reservoirs should be strengthened. The method of data reduction for the initial exploration and provide the stage results. These results show that: reservoir regulation and storage have obvious impact on flood data, and inter-basin water diversion and irrigation water have a significant impact on monthly annual runoff. And propose the adjustment of station network.
