数字湿地及其实现的关键技术框架探讨

Discuss on the framework of digital wetland and its key technologies

湿地作为人类重要的生存环境之一,具有重要和独特的生态环境功能。数字湿地是数字地球的一个重要区域层次,是集数字化、网络化和信息化等多种高新技术为一体的可视化计算机管理和决策的湿地信息系统。数字湿地的构建对于实现湿地资源信息的共享、湿地环境的保护、退化湿地的恢复与重建及流域管理等方面具有重要的现实意义。数字湿地实现的关键技术主要包括数字湿地数据获取、数据存储与处理、数据的高速网络传输与共享、虚拟现实与数字湿地可视化、空间数据挖掘、信息提取与知识发现等方面。

The wetland, as one of the most important ecological environment for human living, has very important and particular ecological and environmental functions. The digital wetland is one of the important regional levels of the Digital Earth, and it could be defined as a kind of high-teeh information system for visible wetland management and decision-making, which is to be integrated by digitalization, network and informationization. The construction of a digital wetland would play meaningful function for wetland resources information sharing, wetland environment protection and degraded wetland restoration, etc. The key technologies in constructing a digital wetland mainly involve data acquisition, data storing and management, data transmission with high-speed network, virtual-reality and visualization, and data space mining and knowledge discovery, etc.
