- Abstract:
-
After entering the 21st century, the development of Yanbian Korean Autonomous Prefecture in all aspects has been further improved, and human activities have seriously affected changes in landscape patterns and ecological service functions. Therefore, studying the evolution of the landscape pattern of Yanbian Korean Autonomous Prefecture and its impact on ecosystem service value is of great significance to the development of border areas in the future. Based on the Fragstas 4.2 software platform and referring to the ecosystem service equivalent factor table, the landscape pattern and ecosystem service value changes of Yanbian Prefecture from 1996 to 2016 were explored; and the impact mechanism of landscape pattern evolution on the ecosystem service value of Yanbian Prefecture was analyzed. The results show that:(1)during 20 years, cultivated land, grassland, and construction land had respectively increased by 371.57 km2, 291.69 km2, and 235.23 km2, respectively, while forest land and water area had decreased by 780.60 km2, and 118.95 km2, respectively, and the degree of fragmentation had increased;(2)over the past 20 years, the total value of ecosystem services in Yanbian Prefecture had decreased by 3.349 billion yuan; the values of ecosystem services in forests and waters had declined significantly, and the values of ecosystem services of cultivated land and grasslands had increased significantly; the distribution of ecosystem service value presented the low level in the central cities and the high level in the surrounding cities;(3)the ecosystem service value was positively correlated with the maximum patch index, spread index and aggregation index, and negatively correlated with the number of patches, patch density, landscape shape index and Shannon diversity index. The results of the study can provide decision-making suggestions for the formulation of land-use policies and sustainable development in this area.
