摘 要:在流域植被生态需水信息管理中,数据关系复杂,信息量庞大,因而确定用什么样的方法实现合理有效的信息化管理显得尤为重要。运用可视化编程工具Visual Basic 6.0和MapObjects组件,开发出山西永定河流域植被生态需水信息管理系统。本研究是在开发前期研究的基础上进行了系统设计、系统的数据库设计以及系统的体系结构设计,实现了对山西永定河流域植被生态需水调查数据的图文一体化管理。并在综合前人研究成果的基础上,在该信息系统中实现了植被生态需水量的计算模型的嵌入。此外还设计实现了信息管理、地图操作、属性查询、空间分析等功能。最后对山西永定河流域植被生态需水量数据进行统计,结果显示该流域每年植被最小生态需水量为256 817.10万m3,最适生态需水量为427 159.6万m3。In the information management course of watershed ecological water requirement of vegetation, that to determine what kind of method to achieve a reasonable and effective information management is very important. The authors utilize Visual Basic 6.0 and MapObjects, develop the information system of watershed ecology water requirement of vegetation of Shanxi Yongdinghe Basin. This study is based on the development of preliminary studies carried out system design, database design and system architecture design. The system realizes integrated management of the texts and maps about Shanxi Yongdinghe watershed ecological water requirement of vegetation. After colligating results of previous studies, design and realize computation model of ecological water requirement of vegetation. The other designed software functions include information management, map operation, attribute query, spatial analysis and so on. Finally, statistical data for the Yongdinghe Basin in Shanxi vegetation ecological water requirement, results show that the minimum ecological water requirement and the suitable ecological water requirement of the vegetation per year is 2. 568 171 ×10^9 m^3 and 4. 271 596 × 10^9 m^3 respectively, according to analyses the data of Yongdinghe Basin ecological wa- ter requirement of vegetation.
