区域生态系统服务权衡与协同关系研究
Research on Tradeoff and Synergy between Regional Ecosystem Services
摘要
Abstract
The climate,vegetation and terrain conditions of the Yangtze River Delta demonstration zone were comprehensively considered;the land use change of the Yangtze River Delta demonstra-tion zone during 2000-2020 was analyzed;and the temporal and spatial distribution of ecosystem service functions such as habitat quality,water production service,carbon storage and food supply was quantitatively calculated with the help of InVEST model.Spearman rank correlation analysis was used to analyze the tradeoff and synergistic relationship between pair ecosystem service functions.The results show that the cultivated land area in the Yangtze River Delta demonstration zone has been continuously reduced,mainly transformed into construction land and water body.The area of construction land gradually expanded,the unused land decreased,the water area increased,and the area of grassland and forest land increased.The spatial and temporal heterogeneity of ecosystem service functions is obvious,and there is a tradeoff relationship between HQ and WY,CS,FP;WY has a synergistic relationship with CS,FP and CS,FP.The tradeoffs/synergies and heterogeneity are obvious under different land use types.The results of this paper provide the basis for ecosystem management planning and regional sustainable development in the Yangtze River Delta demonstration zone.关键词
