초록
The purpose of this study was to analyze the impact of greenhouse cultivation area and groundwater level changes due to the water curtain cultivationin the greenhouse complexes, which are mainly situated along rivers where water resources are easy to secure. The groundwater observation networkin Miryang, Gyeongsangnam-do, located downstream of the Nakdong River, was selected for the study area. We classified the groundwater monitoringwell into the greenhouse (riverside) and field cultivation areas (plain and mountain) to compare the groundwater impact of water curtain cultivation inthe greenhouse complex. The characteristics of groundwater level changes classified by terrain type were analyzed using the observed data. Riversidewells have significant permeability coefficients and are close to rivers, so they are greatly affected by river flow and precipitation changes so that waterlevel shows a specific pattern of annual changes. Most plain wells do not show a constant annual change, but observation wells near small rivers andsmall-scale greenhouse cultivation areas sometimes show annual and daily changes in which the water level drops during winter. Compared to otherobservation wells, mountain wells do not show significant yearly changes in water level and show general characteristics of bedrock aquifer well witha low permeability coefficient.
