Construction of Greenspace Landscape Ecological Network Based on Resistance Analysis of GeoDetector in Jinan.

In the field of landscape ecology, the distribution of different kinds of landscape, determined the resistance in ecological processes such as species migration and energy flow. Various connection ways among them would establish diverse corridors with different resistance. Thus, it was important to choose scientific ecological network with consider of minimum resistance. Based on the land use data in 2010 and 2020, the paper firstly analyzed the spatiotemporal distribution characteristics of greenspace in Jinan, then assessed the influence of each natural and socio-economic factor on the change of greenspace by GeoDetector. The weights of each resistance factor in the ecological process were acquired based on the results of factor detector. Finally, the paper constructed an ecological network of greenspace in Jinan by the minimum cumulative resistance (MCR) method, which would provide scientific basis for decision support of urban plan and management.
