The Application Of The GIS & RS Technology In Water Resources Management Of The Irrigation Area

GIS(Geographical Information System) and RS(Remote Sensing), two new and high technology in developped the "Digital Earth",are increasingly applied to many social fields by their powerful abilities of spatial information analysis, management,storage, analog, data refreshment,decision and forecast.The development of the new century hydraulic information also urgently needs the strong support ofGIS,RS,GPS(3S)and computer technology, specifically,in drought and semi-drought areas,it is an important and urgent task that morden information technology are widely used in development and management of land and water resources.The study takes FengShou irrigation area in Awati County of Aksu Prefecture, Xinjiang as the application example and takes basic survey data, terrain map, TM and ASTER remote sense data as data source,establishing water resources information system ,mainly carrying out the application and study of the GIS & RS technology and developping some related function modules based on the pattern of water resources management .The thesis, by the integration of Powerbuilder and Mapinfo, mainly inserts remote sense vector data of crop land,woodland,waters,grassland,barren land,barren land cultivated in FengShou irrigation area and GIS vector data of village and town district division,trench system network,water gate, depth to groundwater table in FengShou irrigation area into client programs programed, realizing the application of remote sense vector data and GIS vector data in water resoures management of FengShou irrigation area in Awati County, realizing the integrated management of the texts and maps of the water resources survey data, and some spatial analysis and map edit functions of MapInfo as well. The system, which bases on Geographical Information System(GIS) and Remote Sensing(RS) image processing technology, realizes the integrated application of remote sense data as main information source on the Geographical Information System(GIS) plat.
