Abstract:

Based on the forest distribution map of 10 m spatial resolution in 2006 and 2016,the forest in Puzhehei Provincial Nature Reserve of Qiubei,Yunan Province,was divided into 7 types of fragmentation.By using morphological spatial pattern analysis method,the index of forest fragmentation was established to explore the characteristics and changes of forest fragmentation in the reserve.The results show that:from 2006 to 2016,the forest landscape of the reserve has changed greatly and the proportion of various patches in the forest area has increased.The core and edge patches are the main compositions of the forest,while the proportion of island,perforation,connecting bridge,ring and branch patches is relatively small.In the reserve,the forest integrity is enhanced,the edge effect is reduced,the connectivity and the spread are enhanced.The characteristics of forest fragmentation in each functional area are different.The degree of fragmentation in the core area is low,while in the experimental area is just the opposite.The forest in buffer area has better connectivity and spread.Evergreen broad-leaved forest landscape is the most fragmented vegetation type,with many islands and large edge effect,which should be protected and restored.

Key words: nature reserve, morphological spatial pattern, forest fragmentation, vegetation landscape, Puzhehei
