湿地恢复是世界范围内环境管理的主要目标。我们提出了一个区域一级的框架，优先考虑历史生物多样性和恢复适宜性。该框架的目标是最大限度地增加恢复生物多样性的收益，同时将成本降至最低。我们使用C-Plan，一个系统保护规划(SCP)的优先工具，来平衡生物多样性的收益与恢复的成本，或恢复的适宜性。我们叠加了1995年以来的历史空间数据，以估计91个生物多样性特征的历史分布。这些特征被用于进行不可替代性分析，以评估历史生物多样性的恢复价值。然后，我们根据六个标准的环境数据对恢复适宜性进行了建模。最后，我们应用互补性分析来实现所有生物多样性特征的量化目标，同时将恢复成本降至最低。中国，我们在三江平原高度退化的湿地上测试了这个框架。通过将我们的框架应用于三江平原，我们成功地确定了既具有高恢复价值又具有高恢复适宜性的区域。这一划算方案的面积为延伸4620公里(2)，覆盖80%的消失湿地和占整个三江平原4%的面积。与仅具有恢复价值的计划相比，具有成本效益的计划延伸了4486公里(2)，覆盖了更多的区域来实现所有生物多样性特征的目标，但实施成本更低，高恢复适宜性的比例从43%增加到50%。我们的优先排序框架可以用于分析其他区域和生态系统的区域恢复努力，并告知规划者如何在最大限度地增加生物多样性收益的同时将成本降至最低。
Wetland restoration is a major objective of environmental management worldwide. We present a frameworkat the regional level that prioritizes historical biodiversity and restoration suitability. The goal of the framework is to maximize biodiversity gains from restoration while minimizing the cost. We used C-Plan, a prioritization tool for systematic conservation planning (SCP), to balance the biodiversity gains withthe costs of restoration, or restoration suitability. We overlaid historical spatial data from 1995 to estimate historical distributions of 91 biodiversity features. These features were used to conduct an irreplaceability analysis to assess the restoration value of historical biodiversity. We then modelled restoration suitability based on environmental data of six criteria. Finally, we applied a complementarity analysis to achieve the quantitative targets of all biodiversity features while minimizing the cost of restoration. We tested this framework in the highly degraded wetlands ofSanjiang Plain, China. By applying our framework to Sanjiang Plain, we successfully identified areas with both high restoration value and high restoration suitability. The area of this cost-effective plan was an extension of 4620 km(2), covering 80% of the disappearing wetlands and 4% of the total Sanjiang Plain. Compared to the restoration value-only plan, which had an extension of 4486 km(2), the cost-effective plan covered a little more area to achievethe targets forall biodiversity features but with lower implementation costs where the proportion of high restoration suitability increases from 43% to 50%.Our prioritization framework can be used to analyse regional restoration efforts in other regions and ecosystems, and inform planners on how to maximize biodiversity gains while minimizing costs.
