Identifying Source Areas in Urban Wildlife Habitat Networks Based on Species Habitat-Suitability Assessment:A Case Study of Qingpu District,Shanghai
摘要
Abstract
[Objective]This study aimed to develop a species habitat-suitability assessment approach for identifying source areas within urban wildlife habitat networks at the local urban scale,thereby supporting urban biodiversity conservation.[Method]The analysis was conducted at the local scale in Qingpu District,Shanghai.High-resolution satellite imagery was combined with multi-source data on population distribution,road networks,and species records.We first developed criteria for selecting representative species,classifying habitat types,and assessing anthropogenic disturbance.The capacity of individual habitat patches to support target wildlife species was then quantified and adjusted according to the intensity of human disturbance.Based on the integrated suitability assessment,habitat patches with high species-support capacity were identified as source areas in the urban wildlife habitat network.[Result]The empirical research ultimately identified 195.8 km2 of"source"areas with critical habitat value.It is found that farmland habitats constitute the main component of"source"patches;natural or semi-natural habitats adjacent to urban habitats can function as"sources",yet the closer they are to urban habitats,the smaller and more scattered.[Conclusion]By coupling suitable habitats for urban wildlife with key species requirements,this study developed an integrated technical framework comprising habitat classification,representative species selection,habitat species-support capacity assessment,anthropogenic disturbance evaluation,and source habitat identification.The proposed framework provides a methodological reference for incorporating biodiversity conservation actions into local-scale urban spatial planning.关键词
