基于多准则决策分析评价大熊猫受损栖息地恢复优先级OA北大核心CSTPCD

Identifying and prioritizing the restoration of impaired giant panda habitats is a crucial prerequisite for habitat restoration initiatives within the Giant Panda National Park.When park managers decide to undertake habitat restoration work,it becomes imperative to determine the priority areas.The study considers habitat protection and restoration diffi-culty comprehensively,to establish a multi-criteria decision analysis for evaluating the priority areas of habitat restora-tion.This method is based on the analytic hierarchy process and ordered weighted averaging(AHP-OWA),and the Yingjing area of the Giant Panda National Park was selected as a case study to assess the adaptability of the method with-in the National Park.The results indicate that the damaged or impaired habitat covers an area of 4 273.97 hm2,compris-ing nine types and accounting for 5.11％of the total area of the Giant Panda National Park in Yingjing County.Notably,low-quality secondary forests,artificial pure forests and mine area constitute the largest types of damaged habitat.The AHP-OWA decision analysis method quantitatively reveals the trade-off in the'protection-cost'relationship.This meth-od offers a range of priority strategies for restoring damaged habitats under different decision-making scenarios.Ulti-mately,it provides crucial decision-making support for habitat protection and restoration efforts within the Giant Panda National Park.Irrespective of the various scenarios considered,the study identifies the low-quality secondary forests in the high-density distribution area of giant pandas in the northern region of the Toudao watershed along G108 highway as the habitat restoration areas with the highest priority.Given the diverse types of damaged giant panda habitat with vary-ing vegetation and soil characteristics,future habitat restoration efforts should employ measures such as soil restoration,planting,thinning,or striped clear-cutting,tailored to the specific needs of each habitat type.
