Abstract:

As an important part of the East Asia鈥揂ustralia Flyway 锛圗AAF锛夛紝 wetlands along the Yellow Sea play important roles in global biodiversity conservation. Here we examined the wetland landscape dynamics and their driving forces in the western Korean Peninsula by Landsat series images for supporting the coastal ecosystem conservation and management and regional sustainable development. Using a method combining object-oriented and decision-tree classification to obtain the multi-temporal wetland datasets from 1980 to 2018 the wetland landscape pattern锛� the difference in wetland changes and driving forces were compared between North Korea and South Korea. The results revealed that natural wetlands dominate the coastal wetland landscapes in the western Korean Peninsula with 41.1% of the total area of study area. Tidal flat is the main natural wetland type. During the recent four decades锛� the natural wetland in the western Korean Peninsula experienced a consistent areal decline with the total wetland loss of 1 094.4 km2锛� while the human-made wetland got a rapid increase in area with a percentage of 45.1%. Due to the differences in national system锛� politics锛� population锛� and economy锛� most of the natural wetlands in North Korea were converted into cultivated land锛� while the natural wetlands in South Korea were mainly converted into artificial surface. Human activities are the driving forces of wetland changes in this zone and thus require the improvement in controlling anthropogenic threats and sustainable usage of coastal resources.

Key words: Coastal wetlands, The western Korean Peninsula, Remote sensing, Landsat, Driving forces
