摘要:

提出了一种基于生产可能性边界(PPF)的湿地生态系统服务权衡强度计算方法,包括湿地生态系统服务定量评估、权衡关系判定、PPF曲线绘制和权衡强度计算四个步骤。以黄河三角洲湿地为研究对象,对保护情景、现状发展情景及开发情景三种土地利用发展模式下的主导生态系统服务进行了定量化权衡分析。结果表明:各生态系统服务间呈现显著相关关系(R2≥0.9,P<0.01),各发展情景下,栖息地质量与碳储量之间均为协同关系;物质生产与栖息地质量间均为权衡关系,排序为保护情景<基期<现状发展情景<开发情景;而对于物质生产与碳储量之间,在保护及现状发展情景下存在协同关系;而开发情景下转变为权衡关系。该模型通过灵活比较不同生态服务间权衡关系分析进行系列管理规划的方案优选,为实现区域可持续发展提供科学依据。

Abstract:

We developed a four-step method to quantify trade-offs among ecosystem services: evaluate the targeted services at different spatial-temporal scales; identify whether a trade-off exists between pairs of ecosystem services; graph the production-possibility frontier curve; and use that curve to calculate the trade-off intensity between services. Using China's Yellow River Delta wetlands as a case study, we examined the potential trade-offs between material production, carbon storage, and habitat quality under three land-use scenarios (business-as-usual, protection, and exploitation). We found significant correlations between all pairs of the three ecosystem services. Trade-offs existed between material production and habitat quality in all scenarios, with the following order of intensity: protection (6.4) < 2015 status quo (21.8) < business as usual (22.5) < exploitation (24.3). Synergies always existed between habitat quality and carbon storage. The material production and carbon storage services were synergistic in the protection and business as usual scenarios, but they exhibited a trade-off in the exploitation scenario, with a trade-off intensity (59.9) comparable to that (60.3) in the 2015 status quo. The methodology can be flexibly used to analyze trade-offs and compare alternative management plans, thereby revealing the optimal management, which provides a scientific basis for achieving sustainable regional development and resource management.
