基于MSPA-MCR-FLUS模型的葫芦岛市生态安全格局构建
Construction of Huludao's ecological security pattern based on MSPA-MCR-FLUS model
摘要
Abstract
Building an ecological security pattern is an important way to implement the strategy of ecological civilization.Taking Huludao City,Liaoning Province as the research object,the FLUS model was used to predict the land use structure and layout of Huludao City under different scenarios in 2030.Combined with land use prediction data,MSPA and MCR models were coupled to construct the ecological security network of Huludao City,and corresponding ecological construction ideas were proposed.FLUS model simulation results showed that the overall land use layout in different scenarios of Huludao City in 2030 was similar,and there were differences in the changes in the"three living spaces"structure.The four differentiated scenarios set were basically suitable for the different development directions of Huludao City in the future.Under the ecological protection scenario,the ecological security network structure was more complex and had higher connectivity.A total of 25 biological source areas had been identified,mainly distributed in Jianchang County and Suizhong County.There were 50 ecological corridors with a total length of 986.89 km,forming a dense spider web pattern in the central and western regions,and a rare spider web pattern in the eastern coastal areas,extending in a southwest-northeast direction.There were 36 ecological nodes and 97 fault points,mainly located in the ecological corridors of Bailang Mountain and Hongluo Mountain,as well as the ecological corridors of Lingshan and Hongluo Mountain.The study proposed an ecological security pattern construction strategy of"one core,three zones,four belts,and multiple points"to achieve continuous improvement of the ecosystem service function in Huludao City.The research results can provide scientific suggestions for optimizing ecological protection in Huludao City.关键词
