随着电子科学技术的迅速发展,我国水文系统应用计算机整编水文资料已取得了一定的成效。然而由于计算机的外部设备不断更新,现行运用打印机输出电算成果已显得很不够了。因为由计算机整编连续性的水文资料,而得到的只是离散式数据成果,还需要人工进一步整理绘制成有关水文图线,以供各方面的使用。这些绘制图线工作不仅占用人力和时间,而且成图的质量也因人而异。因此,研究由数 With the rapid development of electronic science and technology, our country hydrological system has made some achievements in using computer to rebuild hydrological data. However, due to the continuous updating of the external equipment of the computer, the current output of the computer using the printer has become insufficient. Because computer-aided continuity of hydrological data is only discrete data results, but also need to be further manual finishing of hydrological mapping, for all aspects of use. These drawing lines work not only takes up manpower and time, but also the quality of the mapping varies from person to person. Therefore, the number of studies
