Abstract

In this study,the maps of land use in Gaochang District,Turpan,Xinjiang were obtained using the supervised classification based on the remote sensing images in 2015.The morphological spatial pattern analysis(MSPA) was used to classify the green space landscapes into 7 types based on the data of forest land and grassland in the land use maps.Moreover,the core area and the bridging area,which played an important role in ecological network construction,were extracted to evaluate their connectivity degrees.During this process,the minimum path method was used to establish the potential ecological corridors in the study area.The results showed that the ecological network in the study area was consisted of 26 potential corridors.The corridors were mostly located in the southern part of the study area,and the potential corridors were not so many.The ecological network was not perfect and needed to be further optimized and improved.The research results could be referred in researching the ecological network construction in the highly fragmented area sand in other arid regions.

Key words： morphological spatial pattern analysis (MSPA); landscape connectivity; least-cost path; ecological network; Gaochang District; Turpan
