Biodiversity Conservation Planning Based on Habitat Network Optimization
Urban green space is the key to carrying biodiversity.The construction of habitat network based on urban green space helps to integrate fragmented green patches,promote species exchange and migration,and provide a basis for biodiversity protection.There are some problems in the construction process of the existing habitat network,such as dependence on a single model,neglect of the actual species in the region,lack of unity in the working path of network construction,and difficulty in connecting the output results with the upper planning and practical application in the planning level.This research in the working content and biodiversity conservation planning target,based on habitat quality analysis,geographic detector,minimum cumulative resistance model such as model method,identify regional source of habitats and corridor,and considering the range indicator species added important habitat nodes,build habitat for biodiversity conservation network.The network construction method of"source identification-corridor simulation-node extraction-network construction"was systematically optimized.Docking studies to national spatial planning of green space system under special planning as the goal,the habitat network builds results through comparing red and green space classification matching,and protection measures are proposed from the angle of space control,to realize the effective connection with the green space system planning,and build a unified,standardized work path of biodiversity conservation planning.This study took Tongcheng County as an example to verify the feasibility of the work path,optimize the construction method of habitat network for biodiversity protection,and provide a scientific basis for the planning of the county green space system and biodiversity protection.
