基于GIS的中国地下水资源空间数据库建设

中国地下水资源数据库是国土资源大调查预警工程项目"新一轮全国地下水资源评价"综合研究成果之一.它包含了该项目重新评价的覆盖全国范围的地下水资源与环境的所有空间信息和属性信息,利用先进的GIS技术,较好地实现了科研成果的表现形式由纸介质向数字化信息流的转变,为更大范围地实现数据共享奠定了基础.本文从该数据库系统的总体结构、地下水资源信息的标准化、图层划分、数据采集、建库技术流程、质量控制体系等方面阐述和探讨了中国地下水资源数据库的设计思想及建设过程.

The Construction of Spatial Database for Groundwater Resourcein China Based on GIS

The database for groundwater resource in China constitutes a part of the research achievements of the project "New Round Nationwide Groundwater Resource Assessment" sponsored by the Ministry of Land and Resources. Covering the spatial and attribute information of groundwater resource and environment, it has realized the transition from the paper media to the digitalized information flow so as to represent the achievements in a better way, and has also laid a foundation for realizing the data sharing to a wider extent. This paper deals with the designing thought and the construction process of the groundwater resource database in such aspects as its overall structure, standardization of groundwater resource information, map layer division, data gathering, technical flowing process and quality control system.
