Abstract  

The Information System of Water Conservancy Project Statues for Zhangye City (ISWCPZY) was developed based on the remotely sensed image interpretation and in\|situ Global Position System (GPS) measurement,which were used to collect the geographic spatial data of the water conservancy project statues.The linked attribute data were provided and collected by the Zhangye Water Conservancy Bureau and its subordinate water management stations.The correlative thematic and background information were also collected.The data of the water conservancy project include 159 main canals,782 branch canals,5 315 lateral canals,6 228 pumping wells and 43 reservoirs.The total length of the canals is 8 745.0km.The data collection procedure is introduced in detail and the data quality of the water conservancy project is evaluated preliminarily in this paper,which would afford important reference for the data users.The ISWCPZY was developed by using Components GIS technologies and based on these data resources.The ISWCPZY,as one of the most integrated information management platforms of water conservancy project,has been widely used in the thematic atlas compilation,decision\|making supporting system development,social and economical module development,hydrological model construction,and so on.The canal,as the key information in the ISWCPZY,was analysed on the length ratio of different classes of canals,density,and direction.The results elicit obvious scale effects among the Zhangye City level,county or district level,and water management station level.
