This study surveyed the actual status of reclamation areas in South Pyongan Province, North Korea, using satellite images and literature to survey thecreation date, area, and length of the embankment of the reclamation areas. The reclamation areas in South Pyongan Province were created in threestages, with the first stage completed in the late 1970s or early 1980s, the second stage in the late 1980s or early 1990s, and the third stage in the2000s. The total area of the reclamation areas is 105,570 hectares. The land cover of the reclamation areas is as follows: agriculture (50.5%), saltern(29.5%), water bodies (13.6%), foreshore (12.4%), grasslands (3.0%), bare land (0.4%), facility (0.1%), and forests (0.1%). The study also found thatthe NDVI values of the reclamation areas vary depending on the location. The NDVI values of the Gwiseong and Namyang reclamation areas are low,while the NDVI values of the Samcheonpo and Jigdongbaedali reclamation areas are high. The study found that the NDVI values of the reclamationareas are correlated with the land cover of the reclamation areas. The study’s findings can be used to understand the development direction and regionalcharacteristics of the reclamation areas in South Pyongan Province. The study’s findings can also be used to develop policies and plans for thesustainable development and utilization of the reclamation areas in South Pyongan Province.
Abstract
This study surveyed the actual status of reclamation areas in South Pyongan Province, North Korea, using satellite images and literature to survey thecreation date, area, and length of the embankment of the reclamation areas. The reclamation areas in South Pyongan Province were created in threestages, with the first stage completed in the late 1970s or early 1980s, the second stage in the late 1980s or early 1990s, and the third stage in the2000s. The total area of the reclamation areas is 105,570 hectares. The land cover of the reclamation areas is as follows: agriculture (50.5%), saltern(29.5%), water bodies (13.6%), foreshore (12.4%), grasslands (3.0%), bare land (0.4%), facility (0.1%), and forests (0.1%). The study also found thatthe NDVI values of the reclamation areas vary depending on the location. The NDVI values of the Gwiseong and Namyang reclamation areas are low,while the NDVI values of the Samcheonpo and Jigdongbaedali reclamation areas are high. The study found that the NDVI values of the reclamationareas are correlated with the land cover of the reclamation areas. The study’s findings can be used to understand the development direction and regionalcharacteristics of the reclamation areas in South Pyongan Province. The study’s findings can also be used to develop policies and plans for thesustainable development and utilization of the reclamation areas in South Pyongan Province.
