【 摘 要 】

Remote sensing (RS) and geographic information systems (GIS) have become efficient tools in groundwater investigation, and shown great potential for groundwater surveying. As there is a close connection between groundwater and the surface above, this paper selected lithology, lineament density, drainage density and slope as factors affecting groundwater formation, and thermal inertia and vegetation canopy as indicators of the groundwater occurrence to link surface phemomena to the groundwater potentiality so as to develop a method for groundwater potential mapping. The groundwater-related information was obtained from conventional maps and remotely sensed data using RS and GIS techniques, and they were further processed as thematic layers to assess groundwater potentiality. Analytic hierarchy process were applied to the thematic layers to understand the connection among the layers and the groundwater, and to integrate individual layers to map groundwater potential zones. The map was compared with field-measured well yield data to understand its efficacy in groundwater potentiality estimation, and the resulits suggested that the field measured data and the corresponding index were exponentially related, with a Pearson correlation coefficient of 0.8034.
