수막용수 사용으로 인한 시설재배지역의 지하수 수온과전기전도도 변화 특성 분석

Abstract

This study aimed to analyze the impact of water curtain cultivation in the greenhouse complexes on groundwater’s electric conductivity and watertemperature. The greenhouse complexes are mainly situated along rivers to secure water resources for water curtain cultivation. We classified thegroundwater monitoring well into the greenhouse (riverside) and field cultivation areas (plain) to compare the groundwater impact of water curtaincultivation in the greenhouse complex. The groundwater observation network in Miryang, Gyeongsangnam-do, located downstream of the NakdongRiver, was selected for the study area. As a result of analyzing the electric conductivity and water temperature, the following differences were foundin the observed characteristics by region. 1) The electric conductivity and water temperature of the riverside area, where the permeability is high andclose to rivers, showed a constant pattern of annual changes due to the influence of river flow and precipitation. 2) The flat land in general agriculturalareas showed general characteristics of bedrock observation in the case of water temperature. Still, it seemed more affected by the surrounding well'swater use and water quality. The electric conductivity did not show any particular trend and was influenced by the surrounding environment accordingto the location of each point.
