Abstract

Using the frequency ratio (FR) statistical model can provide a simple geospatial assessment tool to calculate the probabilistic relationship between dependent and independent variables, including constructing multiple classification maps in a geographic information system (GIS) environment. A total of 10,465 springs were identified and mapped in the GIS environment during the research, including 5,302 in the Flysch Belt, 2,832 in the Crystalline complex, 351 in the Paleogene, and 1,980 in the Older Paleozoic. The effective factors - slope, aspect, plan curvature, elevation, topographic wetness index (TWI), stream power index (SPI), slope length (LS), lithology, distance to rivers, distance to ridge-lines, distance to faults, and distance to lithological borders - were derived from a spatial database. Using these effective factors, groundwater spring potential was calculated using a single model, and the results were plotted in ArcGIS. The final result indicated that the bivariate statistical index model (like FR) could be used as a simple tool in the assessment of groundwater spring potential.

基于gis的西喀尔巴阡山脉选定含水层地下水资源潜力评估和制图

使用频率比（FR）统计模型可以提供一个简单的地理空间评估工具来计算因变量和自变量之间的概率关系，包括在地理信息系统（GIS）环境中构建多个分类图。研究期间，共在GIS环境中识别和绘制了10465个泉水，其中复理石带5302个，结晶杂岩2832个，古近系351个，老古生代1980个。从空间数据库中导出了影响因素——坡度、坡向、平面曲率、高程、地形湿度指数（TWI）、水力指数（SPI）、坡长（LS）、岩性、到河流的距离、到山脊线的距离、离断层的距离和到岩性边界的距离。利用这些影响因素，利用单一模型计算了地下水泉势，并将结果绘制在ArcGIS中。最后的结果表明，双变量统计指数模型（如FR）可以作为一种简单的工具来评估地下水泉水潜力。

期刊介绍： Acta Montanistica Slovaca publishes high quality articles on basic and applied research in the following fields: geology and geological survey; mining; Earth resources; underground engineering and geotechnics; mining mechanization, mining transport, deep hole drilling; ecotechnology and mineralurgy; process control, automation and applied informatics in raw materials extraction, utilization and processing; other similar fields. Acta Montanistica Slovaca is the only scientific journal of this kind in Central, Eastern and South Eastern Europe. The submitted manuscripts should contribute significantly to the international literature, even if the focus can be regional. Manuscripts should cite the extant and relevant international literature, should clearly state what the wider contribution is (e.g. a novel discovery, application of a new technique or methodology, application of an existing methodology to a new problem), and should discuss the importance of the work in the international context.
