Abstract

This study analyzed the spatio-temporal change pattern of greenhouse areas for Sangnam-myeon and Samrangjin-eup of Miryang-si in Gyeongnam,which is one of major greenhouse area. First, in order to overcome the lack of statistical data of the distribution of greenhouses, aerial and satelliteimages were interpreted from 1987 to 2018, and the spatial distribution of the greenhouse parcels which has continuously increased was mapped basedon the digital cadastral map. Next, through the emerging hot spot tool in ArcGIS Desktop, the spatio-temporal change in transition from open-fieldto greenhouse cultivation was classified into 9 clusters. About 67.7% of the target area was categorized as a hot spot, and the p attern o f New hot spot,which were recently converted to greenhouse parcels, covered about 34.1%. While, about 11.3% of parcels were expected to keep the existing open-fieldcultivation practice for a while. Overall, the greenhouse parcels have been densely developed along a river and were lately expanding even to the farneighbor. It implied that, in the future, the competition of water intake among farms would be more serious and the environmental responsibility inconsideration of water quality as well as quantity would be getting strengthened due to increasing pollution loads and river intake.
