摘要
以南京沿江两岸各3 km范围内的岸线为研究区域,利用遥感数据通过当量因子法计算2010—2020年研究区生态系统服务价值并探究其演变特征。结果表明:在研究期内,耕地、草地面积有不同程度减少,建设用地占比上升,水域和林地面积变化不大;研究区生态系统服务总价值呈现持续增长的趋势,单项生态系统服务价值呈现不同程度的增减变化,除土壤保持的价值量波动外,其余生态服务价值均保持增长态势。
Taking the coastline within 3 km of both sides of the Yangtze River in Nanjing as the study area,the ecosystem service value of the study area from 2010 to 2020 was calculated by using the equivalent factor method based on remote sensing data and its evolution characteristics were explored.The results showed that during the study period,the area of cultivated land and grassland decreased to varying degrees,the proportion of construction land increased,and the area of water and forest land changed little.The total value of ecosystem services in the study area showed a trend of sustained growth,and the value of single ecosystem services showed varying degrees of increase and decrease.In addition to the fluctuation of soil value,the value of other ecosystem services remained increasing.
