Abstract: The rapid advancement of urbanization in Inner Mongolia pastoral areas has led to the isolation of various green patches, resulting in the continuous reduction of biodiversity and severe habitat fragmentation. Protecting and improving the ecological environment of small towns in pastoral areas has become an urgent need at present. Many previous studies have shown that building a green space habitat network for small towns in pastoral areas is more practical than protecting isolated green patches. Therefore, this study takes the small town of Xinbaolage in pastoral areas as the research object, uses Morphological Spatial Pattern Analysis (MSPA) to identify green space habitat elements, and determines the key habitat sources of the green space core area through landscape connectivity evaluation. Combining the minimum cost distance model (MCR) of ArcGIS software to identify the habitat corridor, it then constructs a green spatial habitat network pattern for small towns in pastoral areas. Finally, it connects the results of Morphological Spatial Pattern Analysis (MSPA) with the green space planning and layout of small towns in pastoral areas, and propose targeted optimization suggestions for implementing green space layout. The study aims to provide methodological references for the theoretical research of green space layout in small towns in Inner Mongolia pastoral areas.
