Résumé partiel
With the implementation of the western development policy, groundwater resources as an important source of water northwest arid and semi-arid areas, the protection of the lives of the residents to support the economic and social development, and to maintain ecological balance have played a very important role, at the same time, water shortages are increasingly become a bottleneck restricting regional development issues. Belonging to the arid and semi-arid areas in Inner Mongolia Erdos City Dalateqi his show once summoned water Groundwater is the main source of water of life of urban residents, therefore, reasonable water source water resources assessment and proposed a reasonable and efficient development mode is particularly important. For the above reasons, the thesis exhibition once summoned water source for the study area, to carry out the following research : 1) first reviewed the status of Groundwater simulation and management model and development history, to clarify our groundwater simulation model and management model the existing problems and lack of prospects of the development trend of the groundwater system simulation model and management model, and lay a good foundation for scientific, objective and accurate evaluation of groundwater resource situation, reasonable modeling. 2) for the accurate determination of hydrogeological parameters of the study area, in this study, the use of nuclear magnetic resonance water system, an MRI test test ; drilling geological hydrogeological holes conducted unsteady flow pumping tests and geological stratigraphic test test ; combined the existing hydrogeological collected hole data, using different methods to determine the hydrogeological parameters of the water source. Also, select the unconfined aquifer permeability coefficient, specific yield and confined water aquifer permeability coefficient, storage coefficient four parametric variable, the use of the spatial variability of the random function theory, system analysis to determine the parametric statistical characteristics and structure function and application logarithmic kriging, Pan kriging, co-kriging system parameters valuation forecast to improve simulation accuracy of evaluation of the groundwater system model. 3) on the basis of detailed analysis of geological and hydrogeological conditions of the study area, the supply of the status quo mining conditions in the study area, excretion resource evaluation. In accordance with the the mineable coefficient method, mining strength method to estimate the amount of available groundwater. 4) hydrogeological conceptual model of the study area and the groundwater system mathematical model using GMS6.0 Software. Creating a simulation model of the aquifer system, give full consideration to the dynamic changes in the characteristics of the various recharge and discharge information. First, the establishment of precipitation infiltration recharge the diving evaporation and precipitation size, the diving evaporation intensity, size of the exploitation and the groundwater level depth curve, followed by the model to reflect the dynamic impact of water resources development of the information. 5) consider industrial structure optimization, rational utilization of water resources, on the basis of the protection of the ecological environment, and other factors, the use of large-scale system decomposition coordination principle, the establishment of a water resource system simulation optimization coupled management model, enabling the analysis of the issue of water resources, forecast , optimization, simulation and management of five one function. Organic coupling application management model and the simulation model of this article, the combination of water resources management time and space, so that the description of complex groundwater system more realistic, flexible, simple, easy to modify, the conduct of this study, to a certain extent on the promotion of the study of the development of the interactive program analysis, also indirectly expands the future direction of development of the water resources management research.
