Do Biotope Area Factor values reflect ecological effectiveness of urban landscapes? A case study on university campuses in central Taiwan

摘要: Abstract In recent years, applying ecological concepts into landscape designs to enhance biodiversity within urban areas has become an important strategy worldwide. A commonly adopted for the development of systems is estimate effectiveness relative mosaics. Biotope Area Factor (BAF) a general methodology that used, however it only considers land use surface types mosaic unit using aerial photos and expert questionnaire method. It not clear whether estimated by BAF system congruent with actual characteristics diversity inhabiting organisms. The practicality are evaluated in this study comparing values homogenous units amongst eight university campuses central Taiwan vegetation density/structure arthropod/plant collected situ. We used linear models evaluate relationship between situ diversities structures. results showed various were partially correlated structure, but incongruent plants arthropod. Our findings indicated current area quantifying may be appropriate. For future studies, we suggest operation scale should adjusted factors influencing considered weighting realistically precisely designate units.
