摘要:
以宁夏固原上黄试验示范区为例，对数字流域构建与应用作了尝试。构建“数字流域”主要包括数据采集及预处理、基础数据库的建立、基础空间信息框架的建立、空间信息的图形库管理、“数字流域”网络化管理与维护五大步骤。“数字流域”加速了流域信息化，为土壤侵蚀及水土保持领域动态模拟、监测提供全新的数据支持平台和虚拟环境，具有重要的理论和实际意义。
Abstract:
The way and use of digital watershed construction is showed taking the Shanghuang experimental area in Ningxia as an example. Construction of digital watershed includes five steps, data collection and preprocess, construction of basic database, construction of basic frame for spatial data, graphic management of spatial information and the web management and maintenance. Digital watershed construction offers a new supporting platform and virtual environment for monitoring and modeling in the fields of soil erosion or water and soil conservation, and accelerate the informationization process of watershed, which has very important significance both in practice and theory.
