数字流域与雨量站网论证技术的集成应用研究

Integration of Digital Basin and Rainfall Network Demonstration Technology

针对传统站网论证方法难以与降雨分布的影响因素相关的局限性,将数字流域引入站网论证方法中,阐述了数字流域建设和信息提取的相关技术,并将数字流域与站网密度、相关分析、雨量等值线、历史洪水预报分析4种站网论证技术进行集成和应用研究。研究结果表明,数字流域与雨量站网论证技术的集成考虑了地形等因素影响,论证结果更合理,其基本思想可为类似的站网论证分析提供借鉴。

There are shortages in correlation between existing method of rainfall network demonstration and influencing factors of the precipitation distribution. We took the digital basin into the methods of rainfall network demonstration, and described the digital basin construction and information extraction technology. The integration of digital basin and rainfall demonstration technology were made in this paper, the technology of rainfall demonstration includes station network density, correlation analysis, rainfall contours and historical flood forecast analysis. The integrated method of digital basin and rainfall network takes into account the influencing of terrain. The basic idea can offer a reference function for other similar rainfall network demonstration analysis.
