多尺度生态系统调节服务价值时空演化分析
Spatio-temporal Evolution Analysis of Multi-scale Ecosystem Regulation Services Value
摘要
Abstract
Taking Yunyang District,Hubei Province as the research area,we explored the spatio-temporal evolution characteristics of ecosystem regulation services value(ERSV)at the plot scale and 30 m×30 m,300 m×300 m,and 1 km×1 km grid scales from 2015 to 2020.The results showed that①the district ERSV decreased with the increase of accounting scale from 2015 to 2020,and showed a trend of first decreasing and then increasing,with an overall increase by 628～727 million yuan,an increase of about 1.41%～1.59%.The plots and grid cells with increased ERSV accounted for 64.73%to 72.99%of the total area.②The ERSV presented more detailed spatial details with the improvement of account-ing scale.The spatial distribution characteristics of ERSV at different scales were"high in the north and south,low in the middle",and the high value areas were mainly located in the forest and wetland ecosystem.③The value of each single regulation service function in Yunyang Dis-trict decreased with the increase of accounting scale.The contribution of climate regulation function to the total ERSV was the largest,and the contribution degree was greater than 44.00%.The results can provide a targeted and scientific basis for spatial optimization,ecological environ-ment protection and restoration in Yunyang District.关键词
