Abstract


Water resources are irreplaceable resource . The issue of water resources is the most serious resource problem facing humanity in the 21st century . The Water Regulating able regional reasonable use of water resources is one of the effective measures to solve the water shortage problem . Remote sensing technology as a cutting-edge technology of the Earth Information Science , is currently the most effective earth observation technology and information access to tools to be widely used in water regulation and storage areas . The Huairou Emergency Groundwater construction projects is an emergency water supply system works to protect the city orderly water supply caused the groundwater level decline , but due to the long-term sustainability of mining water source , groundwater flow field changes , localized landing funnel. Therefore, emergency groundwater source and Shunyi plains of Huairou as the study area , the regional geological data , hydrogeological data collection , collation and analysis ; using remote sensing technology , three-dimensional numerical model of groundwater flow in the study area sources and sinks of precision processing ; proposed constraints to establish the study area water resources optimal regulation and storage model , to determine groundwater resources sustainable use of the program . The main contents are as follows : (1) based on the SPOT remote sensing images , remote sensing digital image processing techniques are discussed . Of ground spectral analysis based on the application of object-oriented method of remote sensing image interpretation, mainly for agricultural information accurate classification results . (2) application of the results of the agricultural information accurate classification The agricultural groundwater irrigation demand as well as irrigation water infiltration the clawback amount of calculation and accurate processing of three - dimensional numerical model of groundwater flow sources and sinks . ( 3 ) the application of groundwater flow three-dimensional numerical model simulation and prediction of groundwater resources for sustainable use of the program under the control of the constraints to determine . In support of remote sensing technology , three - dimensional numerical model of groundwater flow forecast more accurate . Groundwater resources for sustainable use of the program , to provide a scientific basis for the sustainable use and management of Huairou emergency water source for regional water resources rational use of services is determined on the basis of the model predictions .
