Due to the global magnitude of forest degradation and deforestation and the high cost of ecological restoration, several approaches have been used to prioritize conservation or restoration areas based on different objectives and criteria. The present work aims to develop a multicriteria approach to defining forest restoration priority areas in the Itacaiúnas River basin, eastern Amazon, that maximizes the criteria equitably. The selected criteria were: improve forest connectivity, provide climatic refuges for biodiversity, mitigate the impacts of deforestation on streamflow, and improve the probability of natural regeneration. A strong difference between selected areas was observed when the criteria of forest connectivity and mitigate the impact on streamflow were considered separately, but greater equity among the criteria was achieved using the multicriteria approach. The most priority areas were concentrated near protected areas. The method used provides a flexible framework, and different criteria or subarea selections can be applied for different purposes to facilitate adaptive management. Analyzing forest restoration prioritization on rural properties can provide guidance for conserving and restoring biodiversity at the landscape scale while complying with legal requirements.
由于森林退化和毁林的全球性规模以及生态恢复的高昂成本，已经采用了几种方法来根据不同的目标和标准优先考虑保护或恢复区域。本工作旨在为亚马逊东部伊塔卡亚努纳斯河流域制定一种多标准方法，以最大限度地公平地确定森林恢复优先区域。所选标准为：提高森林连通性、为生物多样性提供气候避难所、减轻毁林对径流量的影响以及提高自然再生的可能性。当分别考虑森林连通性和减轻对径流量的影响的标准时，观察到所选区域之间存在明显差异，但使用多标准方法实现了各标准之间更大的公平性。最优先区域集中在保护区附近。所使用的方法提供了一个灵活的框架，可以根据不同的目的应用不同的标准或子区域选择，以促进适应性管理。分析农村土地的森林恢复优先级可以在遵守法律要求的同时，为保护和恢复景观尺度上的生物多样性提供指导。
