Evaluation And Prediction Of Groundwater Enrichment Based On Domestic High-resolution Data

Along with the development of the domestic satellite,especially the rapid progress of domestic high satellite,spatial resolution and spectrum resolution of remote sensing data increased significantly,from dozens of meters,a few meters has been raised to a few centimeters,and accumulated a lot of remote sensing data.Under the background of such remote sensing development,how to apply the vast amount of domestic remote sensing data and avoid the waste of data resources has become a serious problem for the national remote sensing industry.In order to solve the problem,the primary goal is to actively expand the application field and find the breakthrough and joint point of domestic satellite and remote sensing technology.From the perspective of geology,this paper explores the application of remote sensing technology in groundwater conservation by combining with the domestic high score satellite,so as to make some contribution to the development of domestic satellite.Since the 60 s,more and more researchers using aerial photograph,interpretation of satellite image and remote sensing methods,the study area of groundwater formation,storage and movement characteristics,and the change rule of water quality,water quantity,and combined with various mathematical analysis method to improve the objectivity and reliability of results,and increasingly brought to the attention of the researchers in hydrogeology.Remote sensing technique can not only save unnecessary consumption of manpower and material resources in the exploration of the field,can also be conducted on macro planning,development and reasonable utilization of groundwater resources,with fast,convenient,obvious advantage.In this paper,based on the high score of remote sensing data no.1 and no.2,liaoning chaoyang as study area,combining with the relevant hydrogeological data,collected by spatial analysis functions of GIS technology and the field survey,the extraction and analysis of remote sensing image information reflect the topography,land use status quo,drainage,geological structure,hydrogeological characteristics,and on the basis of exploring to establish a scientific and reasonable forecast model,more quickly and effectively forecast the water enrichment region,for the area of hydrogeology survey field work provide certain reference basis.The author collected by previous hydrological geological data and the analysis and study of relevant literature,established the evaluation index of groundwater potential prediction,and comparing advantages and disadvantages of various mathematical methods,fuzzy analytic hierarchy process(AHP)to select the evaluation factors of groundwater in weight distribution.Eventually determine the indicators for the assessment of landscape type,land use present situation,the terrain slope,precipitation,hydrogeology types,the development and structure of river water system,and through the fuzzy analytic hierarchy process(AHP)to evaluate the index analysis demonstration area of groundwater enrichment region distribution were obtained,which selects five rich water area of the precision of the early stage of the drilling data validation,has certain persuasive,after for the study of the Chaoyang district of groundwater resources exploration provides several relatively reliable rich water area,as well as similar hydrogeological conditions area of hydrogeological prospecting work provide effective reference and guidance.
