摘要： Constructing an urban ecological corridor system is a major component and critical factor of forming an effective network within an urban ecosystem. Shenzhen, as a highly urbanized area in China, is facing the dual pressures of urban development and ecological conservation. The ecological corridors in Shenzhen are being constantly eroded by urban expansion, resulting in an urgent need to carry out sensitivity evaluations and ecological land management studies. By identifying the spatial range of planned ecological corridors in Shenzhen, we develop a GIS-based ecological sensitivity evaluation model from the perspectives of soil environment, habitat conditions, geological hazards, and human disturbance. Management strategies are proposed with regard to macroscopic protection guidance and microscopic land-use control. The results show that there is little difference in the sensitivity grade of ecological corridors in Shenzhen. With regard to spatial distribution, the sensitivity level is high in the north and low in the south, with moderately sensitive corridors being the dominant type. Meanwhile, we design the land-use control program by taking into account the present management and new land demand and provide the path for implementing the withdrawal, reservation, occupation, and avoidance polices. The results of the sensitivity evaluation objectively reflect the eco-environmental condition of ecological corridors in Shenzhen. The classified and graded protection guidance and space regulatory framework proposed in this study are of significance for guiding the ecological conservation, land use, and sustainable development in urban contexts with similar issues.
