Optimization of Landscape Ecological Security Patterns and Planning in Low Hilly Areas —A Case Study of Beigong Town, Fengtai District, Beijing City, China

With the continuous expansion of mega-cities in China, the landscape pattern of the original urban-rural area is broken, resulting in serious fragmentation of landscape patches in the fringe area of the urban center and threatening urban ecological security. Therefore, how to consider the needs for construction and development based on securing ecological security patterns is a key consideration for the fringe areas of megacities. The study takes Beigong Town as the research object and uses the MSPA model analysis method to extract nine ecological source sites that are important for ecological network construction. Then, the study constructs a comprehensive ecological resistance surface based on the MCR minimum cumulative resistance model, generates minimum cost paths to simulate regional potential corridors, and constructs the ecological security pattern in Beigong Town. The study further combines the current situation of land use in Beigong Town to optimize the ecological safety pattern and proposes the planning control systems, which provides the basis for the next planning and construction
