基于ArcGIS Engine的暴雨参数自动查算系统设计与实现

由于小流域一般缺乏实测水文资料，设计洪水多根据各省的设计暴雨洪水查算手册，查算各暴雨洪水参数，间接推求。但暴雨参数种类繁多，传统的手工查算任务繁重，影响工作效率。本文主要探讨基于ArcGIS Engine开发暴雨参数自动查算系统的系统设计依据、查询数据库建立途径及系统功能实现方法，在查算数据库建立时考虑了经纬度坐标的运用，提高了工程定位的准确性。通过应用于江西省暴雨参数查算的实例验证了其可行性、可靠性和高效性。

英文摘要:

Due to the general lack of Hydrological data in small watershed，usually，we indirect Calculation the design flood of small watershed by check the rainstorm parameters according to the Storm flood manual. However，there are many kinds of rainstorm parameters, the traditional manual searching task is arduous and affects the working efficiency. This paper mainly discusses the system design basis, query database establishment method and system function realization method of the automatic calculation of rainstorm parameters system based on ArcGIS Engine.The use of longitude and latitude coordinates is taken into account in the establishment of the database, which improves the accuracy of project positioning. The feasibility, reliability and efficiency of the method are validated by the example of the rainstorm parameter calculation in Jiangxi Province.
