水文模型空间数据库的建立——以普定后寨河流域为例

Establishment of Spatial Database for Hydrological Model ——A Case Study of Houzhaihe Catchment of Puding

在水文模型研究中 ,往往要利用多种信息 ,包括属性数据和空间属性数据 ,这些数据只有在地理信息系统的管理下才能方便地为水文模型所利用 ,因此有必要建立一个水文模型空间数据库。本文 ,以后寨河流域为例 ,阐述了水文模型空间数据库的建立过程。建立的空间数据库不仅十分有利于水文模型的建立与校验 ,同时在空间信息查询、专题图件的生成与管理。

In the study of hydrological modeling a lot of information which has different sources, including spatial information, has been involved. It is necessary to set up a Spatial Information System that all of those information can be used in hydrological models easily by using a Geographical Information System to manage the various information. In this paper, the procedures of a spatial information system for Houzhaihe catchment at Puding in Guizhou province have been discussed detailedly. With the support of the spatial information system, the information query, thematic maps generation and management landuse assessment as well as hydrological models setting up and calibration are very convenient.
