摘要： 以吐鲁番市高昌区为例,利用2015 Landsat,通过形态学空间格局分析(MSPA)方法,将绿地景观划分为7种类型;然后从MSPA景观类型中提取对生态网络构建具有重要作用的核心区和桥接区进行连接度评价,根据结果选取“源地”;采用最小路径方法建立研究区的潜在生态廊道。结果表明:该研究区生态网络是由26条潜在廊道组成,廊道大多分布在研究区南部,潜在廊道数目较少。该成果可为干旱区的生态网络构建研究提供参考和依据,具有一定的借鉴意义。

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.
