Abstract

The accelerating process of urbanization leads to the fragmentation of landscape patches.The construction of ecological network can improve the landscape connectivity between patches,which is of great significance to protect the ecological environment and enhance the ecosystem service function.Taking Tengchong City center as an example,this paper used morphological spatial pattern analysis (MSPA)and landscape connectivity index to identify the ecological source,constructed the potential ecological corridor based on ArcGIS software minimum cost distance model (MCR),and used gravity model to judge the importance of the corridor.1)Combined with MSPA and landscape connectivity analysis,the top 12 patches with plaque importance (dPC)value>1 were selected as important ecological source areas,which enhanced the scientificity of source patch selection and avoids the subjectivity of previous artificial selection;2)Based on the MCR model of ArcGIS software,66 potential ecological corridors were generated to quantitatively analyze the best migration path of species between multiple patches;3)Using the gravity model to quantitatively evaluate the interaction force between source patches,this paper scientifically judged the important corridors (strength > 300)and general corridors,analyzed the importance of ecological corridors between patches,and finally obtained the ecological network of the study area.The analysis was conducted by combining various methods,in order to provide theoretical reference and scientific basis for the construction of ecological spatial network in landscape fragmentation area.

Key words： MSPA; landscape connectivity; minimum path; ecological network; central city
