RESEARCH ON THE EVALUATION METHOD OF ECOLOGICAL NETWORK STRUCTURE BASED ON THE MODULARITY DEGREE
Currently,China is carrying out territorial spatial planning with the theme of ecological civilization.The traditional ecological network structure optimization method of land ecological space only evaluates the functional importance of patches and corridors and does not consider the structural significance of ecological patches in the net-work.To solve the problem of lack of structural importance evaluation of ecological patches in the network,this pa-per proposes a modularity-based ecological network structure importance evaluation method from the perspective of complex network structure analysis.The application of the method is verified within Harbin city.The results show that modularity can be used for ecological network structure optimization,and the network structure with high modu-larity is more stable than that of tradition method.Identifying key strategic points maintains the stability of the eco-logical network structure and provides a basis for the game between ecological space,urban space,and agricultural space in territorial spatial planning.
