How to assort with the relationship between the urban construction and the maintenance of ecological
security is a hot issue during the process of urbanization. The purpose of this study is to identify the key
ecological land maintaining ecological security and to put forward some measures for environmental
management. Based on the GIS technology, from the view of water security, biodiversity conservation,
disaster protection, natural recreation security, and human disturbance, an integrated index is put
forward to evaluate the ecological importance of regional space. Then, a GIS-based approach for
evaluating ecological importance was created, with Xingguo county of China as a case study. The results
show that the area of core eco-space in the study area accounts for 30% of the total area. These areas
mainly consist of the core areas of regional river systems, wetlands, nature reserves, forest parks, and
scenic spots and the endangered and protected zone of geological hazards. According to the spatial
characteristics of ecological importance for different regions, this study proposes some zoning
regulations and measures for environmental management.
