摘要：

The trade- off and synergy analysis of ecosystem services is a hot topic in current research on ecosystem services, which can provide scientific basis for ecosystem management. Based on ecological functional areas in Hebei province, this study evaluated the value of four ecosystem services, including food production, carbon storage, soil conservation and water conservation. Then the trade- off and synergy of ecosystem services in different ecological functional areas were analyzed through the spatial overlay method. The results showed that the total grain production in Hebei province was 38.28 million tons in 2017, and the contribution ranking of the five major ecological areas is Low Plain Ecological Restoration Area (PY) > Yanshan and Taihang Mountains Ecological Conservation Area (YS) > Surrounding Beijing and Tianjin Ecological Transition Zone (HJJ) > Bashang Plateau Ecological Protection Zone (BS) > Coastal Ecological Protection Zone (YH). The total amount of carbon storage, soil conservation, and water conservation services in Hebei was 85.7 million tons of carbon, 4701.61 million tons of soil, and 6568.75 million tons of water, respectively. These three services exhibit a similar spatial pattern, with the contribution of Yanshan and Taihang Mountains Ecological Conservation Area was the highest, while the contribution of other ecological functional areas was generally lower. Strong trade- offs and low synergies among different ecosystem services were the main relationship. The area proportions of strong tradeoffs, low synergies, weak trade- offs, and high synergies were 48.15%, 45.92%, 5.09%, and 0.83%, respectively. The dominant function of strong trade- offs in ecosystems was basically consistent with the functional positioning of the ecological zone where it is located, which can provide basis for the better play of the dominant function of the ecological functional zone. This study can provide new ideas for managers to optimize the trade-off and synergy effects of ecosystem services from the perspective of ecological functional zones. © 2023 Science Press.
