基于土地利用变化的抚州市生态系统服务价值变化研究

Study on change of ecosystem service value in Fuzhou City based on land use change

基于2010年的土地利用现状变更数据以及2020年的第三次国土调查变更数据对江西省抚州市域的生态系统服务价值及其变化进行了研究。结果表明,2010—2020年抚州市水域和建设用地面积增量及单一动态度最大,未利用地、草地和湿地减少幅度较大,耕地减少面积最大,以草地、耕地转为林地,耕地、林地转为建设用地的土地转移方向为主;2010—2020年抚州市生态系统服务价值呈上升趋势,净增加量为136.68亿元,其增加主要来源于水域与林地面积的增加;生态系统服务价值的增值区与减值区在空间上呈分布不均匀的特点,对此应加强生态环境建设补偿机制建设,促进抚州市未来生态环境的平衡与协调发展以及经济的可持续发展。

The ecosystem service values and their changes in Fuzhou City,Jiangxi Province were studied based on the change of land use status data in 2010 and the change of the third land survey data in 2020.The results showed that,from 2010 to 2020,Fuzhou City had the largest area increase and single dynamic degree of water and construction land,the relatively larger reduction range of unused land,grassland and wetland,and the largest decrease of arable land area;the main direction of land transfer was the conversion of grassland and arable land to forest land,and the conversion of arable land and forest land to construction land.From 2010 to 2020,ecosystem service values in Fuzhou City showed an upward trend,the net increase was RMB 13.668 billion yuan,and the increase mainly came from the increase of the area of water and forest land.The spatial distribution of the value-added and value-impaired areas of ecosystem service value was uneven.Therefore,the construction of compensation mechanism for ecological environment construction should be strengthened to promote the balanced and coordinated development of ecological environment and sustainable economic development in Fuzhou City in the future.
