Landscape fragmentation and habitat loss are one of the important factors resulting in biodiversity decrease and species extinction. A large amount of Eucalyptus have been introduced into Yunnan Province in China since 2003, replaced the native forest, farmland, wasteland and other ecosystems, leading to natural habitat loss and landscape fragmentation. In order to protect habitat and the biodiversity, the secondary evergreen broad-leaved forest were selected as “protection source”, land cover types, altitude, slope and soil texture were selected as resistance factors, to construct a medium-security and high-security level landscape eco-security patterns for Eucalyptus introduction regions by using the minimum cumulative resistance model and GIS technology. The patterns were composed of the eco-security pattern compositions and ecological function zones. The eco-security pattern compositions were composed of corridor, radiating routes and strategic point etc. The ecological function zones were composed of key eco-protection zone, eco-buffer zone, eco-transition zone, Eucalyptus planting zone, Eucalyptus banned zones, farming zone, living zone etc.
