The Adaptive Partition Of Shallow Geothermal Energy Application In Chongqing Area

Shallow geothermal energy refers to the reserves in a certain depth below thesurface within the rock and soil, groundwater, surface water development and utilizationof the value of geothermal energy, is a new kind of renewable green energy.Development and utilization of shallow geothermal energy in China less, coupled withthe intense and disorderly competition in the market and the lack of strict market accesssystem, and many cities in the survey and evaluation of shallow geothermal energy, didnot formulate a scientific development program, the blind development of shallowgeothermal energy, so they should not be used with a suitable place contrary useless"phenomenon, not only caused a serious waste of resources, is not conducive to shallowpromote the development of geothermal energy industry.For the above phenomenon, the paper the Chongqing shallow geothermal able todevelop the use of appropriate zoning, the purpose is to determine the Chongqing areaof shallow geothermal energy resources suitable for development and utilization of theregion and its rational development for the Chongqing region as well as south westregion of shallow geothermal energy development and utilization of resources toprovide a scientific basis to ensure that local shallow geothermal energy developmentand utilization of resources in the future, should economic and environmental benefits.In this paper, the1670km2the scope for the Chongqing city in the study area, theoccurrence of the basis for the study area within the scope of the shallow geothermalhydrogeological conditions made a detailed analysis of the survey, then the geotechnicalthermophysical properties in the region parameters test site geothermal monitoring data,the results of the in-depth analysis of the thermal performance characteristics of theaquifers with the next comprehensive evaluation method to establish district evaluationmodel using the analytic hierarchy process and non-structural fuzzy assignment methodto determine the project the index weights Finally, application of MAPGIS6.7softwareto partition the total score calculation grid points within the study area, and spatialanalysis, Chongqing region in shallow geothermal energy development and utilizationof appropriate partition results.This work is to commence for the first time in Chongqing region, the specialstructural characteristics of the bedrock strata of the Chongqing region, shallowgeothermal energy application of adaptive partition, shallow geothermal energy use inthe rational development of the Chongqing region have an important reference value.
