基于集成物种分布模型的历山华北豹栖息地研究
Habitat study of the northern Chinese leopard in Alexandria based on an integrated species distribution model
摘要
Abstract
Habitat,as the fundamental basis for the survival,reproduction,and development of organisms,plays a crucial role in maintaining populations,preserving species diversity,and ensuring the balance and stability of ecosystems through its quality and integrity.The North China Leopard(Panthera pardus japonensis),a subspecies endemic to China,serves as a keystone predator within its ecosystem.However,it faces significant threats,particularly habitat fragmentation.Despite its ecological importance,research concerning habitat suitability and environmental preferences within the Lishan Nature Reserve remains limited.This study integrates past research literature on the North China leopard,relevant information,and monitoring data with corresponding environmental data,to construct an ensemble species distribution model(ESDM)that evaluates habitat suitability.By incorporating relevant environmental data,the model explores the environmental preferences of the North China leopard in the study area.Additionally,a comprehensive analysis is conducted based on the current configuration of different zones within the protected area.This approach provides insights into the factors influencing the distribution and habitat use of the North China leopard,aiding in the development of targeted conservation strategies.The result indicated that over 40％of the reserve remains suitable habitat for the North China Leopard.In terms of spatial distribution,the moderately to highly suitable habitats within the reserve are composed of large,continuous patches on the eastern and western sides,as well as numerous fragmented patches.The discontinuity of suitable habitats within the reserve may impose certain limitations on the dispersal of the North China leopard in the area.The environmental preferences of the North China leopard include areas with medium altitudes,dense vegetation,rugged terrain,close proximity to water sources,and significant precipitation variability.Interestingly,there was no evident inclination to avoid inhabited areas.These findings suggest that while the reserve has made progress in conserving suitable habitats for the North China Leopard,challenges such as habitat fragmentation and insufficient coverage of core conservation zones persist.Therefore,it is recommended that the conservation strategies for the North China leopard within the protected area be dynamically adjusted in response to habitat changes.A series of scientific management measures should be implemented to address these challenges.These measures include strengthening the monitoring of human activities to minimize disturbances,conducting habitat restoration projects to enhance the quality and connectivity of suitable habitats,and establishing mechanisms for the maintenance of ecological corridors to facilitate the movement of the leopards.Such initiatives are crucial for promoting the recovery and dispersal of the North China leopard population in the region.By adopting these adaptive conservation strategies,the long-term survival and ecological role of the North China leopard can be better supported,contributing to the overall health and stability of the ecosystem.By adopting these adaptive conservation strategies,the long-term survival and ecological role of the North China leopard can be better supported,contributing to the overall health and stability of the ecosystem.关键词
