- Abstract:
-
The spatio-temporal changes of ecosystem services, trade-offs and synergies of ecosystem services were explored to provide decision-making reference for formulating ecological protection policy and regional sustainable development in the future. Based on the land use classification data of the Anhui Province from 1990 to 2018, the equivalent factor method, GIS spatial analysis and GeoDetetor were used to depict the spatial geographical pattern of ecosystem services values(ESV), then the trade-offs and synergies was explored, spatial heterogeneity of the county ESV was quantitatively detected, and the interaction mechanism between the ESV and the geographical environment was revealed. The results showed that:(1)the ESV in Anhui was decreasing from 3 647.37 billion yuan in 1990 to 3 567.78 billion yuan in 2018;(2)in terms of spatial distribution, the spatial distribution pattern of ESV in Anhui Province changed little and the spatial heterogeneity was obvious from 1990 to 2018;(3)there was significant heterogeneity of trade-offs/synergies between ecosystem services on the spatial pattern; the tradeoffs and synergies of ecosystem services varied with different spatial scales;(4)the spatial differentiation of ESV was affected by a variety of factors; the difference in density of population and HAI had always been the most decisive factor for the spatial differences; in the interaction detection, each factor had significant differences in the spatial distribution of ESV, and showed a two-factor enhancement. Therefore, the tradeoffs and synergies of ecosystem services had spatial heterogeneity, and synergistic development of multiple ecosystem services should be spatially promoted at spatial scale in the future.
