This study aimed to analyze the recent status and changes in impervious surface areas and their ratios across regions in Gyeongsangnam-do, providing fundamental data for regional development and impervious surface management. Based on the ‘Guidelines for Calculating Water Cycle Management Indicators for Nonpoint Pollution Source Control(Ministry of Environment)’, we processed the land characteristics survey map(shapefile) from 2018 and 2022 to analyze impervious surface area and their rates by administrative boundaries. The impervious surface area in Gyeongsangnam-do increased from 75,652 ha in 2018 to 81,055 ha in 2022, with the rate rising by 0.51% from 7.18% to 7.69%. The average of impervious surface area across 545 eupmyeon units expanded by approximately 9 ha, from 139.8 ha in 2018 to 148.8 ha in 2022, with the rate increasing by 0.71%. Concurrently, the whole population declined by 2.8% while the number of households surged by 6.4%, correlating with the growth in impervious areas. Despite population decreases, factors such as population migration, increased household fragmentation, new residential developments, and industrial facility expansions have consistently contributed to the rise in impervious surface area. Notably, even in areas with high impervious surface area rate, significant disparities existed between urbanized areas and predominantly rural regions. Furthermore, about 333 units(61% of the whole eupmyeons), showed negligible changes in their impervious surface area rate, with an increase of less than 0.5%.
Abstract
This study aimed to analyze the recent status and changes in impervious surface areas and their ratios across regions in Gyeongsangnam-do, providing fundamental data for regional development and impervious surface management. Based on the ‘Guidelines for Calculating Water Cycle Management Indicators for Nonpoint Pollution Source Control(Ministry of Environment)’, we processed the land characteristics survey map(shapefile) from 2018 and 2022 to analyze impervious surface area and their rates by administrative boundaries. The impervious surface area in Gyeongsangnam-do increased from 75,652 ha in 2018 to 81,055 ha in 2022, with the rate rising by 0.51% from 7.18% to 7.69%.
