摘要
随着城市化步伐的加快,持续扩张的城市建设用地导致物种栖息地不断流失,生态廊道作用有限或受到挤占,生境破碎化程度日益严重。利用图论中最短路径算法和ArcGIS的空间分析功能,对生境中动物迁徙廊道的识别与构建进行研究;在此基础上提出通过生物迁徙廊道构建生物栖息地的概念,对区域的生物栖息地进行生态恢复与重建,保持区域物种多样性起到关键作用。该方法为区域土地管理以及生态环境保护规划提供一定的科学依据。
With the acceleration of urbanization, the continuous expansion of urban construction land has led to the continuous loss of species habitats, the role of ecological corridors has been limited or occupied, and the degree of habitat fragmentation has become increasingly serious. Using the shortest path algorithm in graph theory and the spatial analysis function of ArcGIS to study the identification and construction of animal migration corridors in habitats. On this basis, the concept of constructing biological habitats through biological migration corridors is proposed, and ecological restoration and reconstruction of biological habitats in the region are played to maintain the key role of regional species diversity. This method provides a certain scientific basis for regional land management and ecological environmental protection planning.
