Abstract
Scientifically understanding the trade-off and synergy relationship among ecosystem services of cultivated land is of great significance for cultivated land protection and the refined management of ecosystem services. This study quantified four typical cultivated land ecosystem services in the Yangtze River Delta from 2000 to 2020 through models such as InVEST and MaxEnt. The difference comparison method was adopted to identify the trade-off and synergy relationships among ecosystem services， and the geographical weighted logistic regression was used to reveal the influence of different influencing factors on the trade-off and synergy relationships. Finally， the cultivated land in the study area was zoned and optimized with the aid of the production-possibility frontiers. The results showed that： ① During the research period， grain production presented a spatial distribution pattern of "high in the north and low in the south，" while the spatial distribution of carbon sequestration and habitat quality was opposite to that of grain production. The high-value areas of recreation service gradually shifted from the northern part of the Yangtze River Delta to the central and southern parts. Between 2000 and 2020， grain production increased significantly by 33.97%， while other ecosystem services declined slightly to varying degrees. ② Overall， carbon sequestration-grain production and habitat quality-recreation service showed a synergistic relationship， while other ecosystem services showed a trade-off relationship. The trade-off and synergy relationship among ecosystem services had obvious spatial heterogeneity. ③ The synergy relationship of ecosystem service trade-off mainly showed a significant negative response to precipitation and mainly showed a significant positive response to the urbanization rate and population density. ④ Based on the trade-off intensity of ecosystem services， the cultivated land in the study area was divided into the vulnerable area， the single dominant trade-off area， the balanced development area， and the coordinated development area. Among them， the overall trade-off intensity of the vulnerable area was relatively high， accounting for 24.92% of the study area， and it is a key area for future ecological restoration and optimization improvement. This article aims to provide a scientific basis for the refined management of cultivated land in the Yangtze River Delta and offer a reference for the optimization of the spatial pattern.
