基于MSPA分析的牧区小城镇绿色空间布局研究——以镶黄旗新宝拉格镇为例

Research on Green Space Layout of Small Towns in Pastoral Areas Based on MSPA Analysis:Taking Xinbaolage Town in Xianghuang Banner as an Example

内蒙古牧区城镇化进程的快速推进,导致各类绿地斑块彼此孤立,引发了生物多样性不断降低和生境破碎化严重的问题,保护与改善牧区小城镇的生态环境成为当前的迫切需要。诸多研究已经证明构建牧区小城镇绿色空间生境网络比保护孤立的绿地斑块更具实际意义,因而,本研究以牧区小城镇—内蒙古自治区锡林郭勒盟镶黄旗新宝拉格镇为研究对象,利用形态学空间格局分析法(MSPA)对绿色空间生境要素进行识别,通过景观连通性评价确定绿色空间核心区的关键生境源地,结合ArcGIS软件最小成本距离模型(MCR)识别生境廊道,进而构建出牧区小城镇绿色空间生境网络格局。最终将形态学空间格局分析(MSPA)结果与牧区小城镇绿色空间规划布局衔接,并针对性提出实施绿色空间布局的优化建议,以期为内蒙古牧区小城镇绿色空间布局理论研究提供方法参考。

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.
