| 摘 要： | 针对小流域数据种类多、数据量大的特点,利用PostgreSQL的空间扩展插件PostGIS实现对小流域的空间数据以及影像数据的存储与管理,并利用Python和JDBC技术实现对小流域基本属性数据及长时间序列的小流域降雨、径流数据的存储与管理。本文提出了对小流域不同数据类型数据存储的数据库设计思路,实现了小流域多类型数据的统一管理;同时,本文结合WebGIS技术发布相应的网络服务,实现数据的可视化以及管理应用。

| Abstract: | In view of the characteristics of large amount and variety of data in small watershed,PostGIS,a spatial extension plug-in of PostgreSQL,is applied to store and manage the spatial data and image data for small watershed. Python and JDBC techniques are used to store and manage the time-series rainfall-runoff data and the basic attribute data for small watershed. We put forward the design thought of database for storing and integrated managing multiple types of data in small watershed. We also implement data visualization and application through publishing the corresponding network services based on WebGIS technique. |
