空间信息技术在水利普查中的应用

Application of Spatial Information Technology in Water Census

2010年开展的全国第一次水利普查是建国以来水利行业水利基础数据全口径调查,分为清查阶段、普查阶段、数据汇总阶段和成果展示及开发利用3个阶段,涉及河湖基本情况普查、水利工程基本情况普查、经济社会用水情况调查、河湖开发治理保护情况普查、水土保持情况普查、行业能力建设情况普查、灌区专项普查、地下水取水井专项普查等8大专项。在3个阶段和8大专项中,空间信息技术都得到了充分利用。特别是河湖基本情况普查和水土保持情况普查调查,主要是依靠空间信息技术,采用内业获取和处理的方式获取相关信息。在成果展示及开发利用方面,以空间信息技术为技术支撑,实现了普查成果"一张图"展示,直观展示了空间信息技术在水利行业中全面和深入的应用。

The first national water census in 2010 was an overall survey for basic water data since the founding of the People＇s Republic of China. It is divided into three phases： inventory, general investigation, data summarization and results display. The water census involves eight investigations： the basic situations of rivers and lakes, water conservancy projects, economic and social water consumption, development and protection of rivers and lakes, con- servation of water and soil, water industry capacity building, and specialized investigation on irrigation area and groundwater wells. During the three phrases and the eight investigations, spatial information technology has been applied extensively. Especially, the investigation of rivers and lakes and conservation of water and soil mainly de- pends on the spatial information technology： the data was mainly acquired using remote sensing image interpreta- tion. During the phase of results display and results development and utilization, spatial information has been used as technical support. All water census results are displayed in a map, which directly reflects the extensive and in- depth application of spatial information in the water industry.
