The landscape patterns of UGS have not improved with town renewal and developments. Some old districts have relatively low-quality landscape attributes. Vegetation-dominated land uses often have more interfacial benefits. UGS in land uses with less human disturbance tend to be larger and more homogeneous. r t i c l e i n f o rticle history: eceived 17 April 2013 eceived in revised form 0 September 2013 ccepted 2 October 2013 vailable online 29 October 2013 eywords: ompact city cological quality andscape characteristics a b s t r a c t The interrelated nature of landscape metrics calls for their joint application in analyzing complicated landscape patterns and associated ecological processes. Using geographic information system, remote- sensingand factor-analysis techniques, the landscapepatternsofurbangreenspaces (UGS) in thecompact city of HongKongwere analyzed for their landscape-ecological quality in different land uses and districts. Using the Fragstat software, some key indices were selected to characterize the landscape mosaic with reference to patch size, patch shape, proximity relationship and edge configuration. Some old districts have smaller and more heterogeneous UGS than newer ones due to relatively low-quality landscape attributes. The landscape patterns of UGS have not improved with ol
