摘要:

基于2006年和2016年10 m空间分辨率森林分布图,利用形态学空间格局分析法将云南省丘北普者黑省级自然保护区森林分为7种不同破碎化类型;建立森林破碎化指标,探索保护区森林破碎化特征及其变化情况。结果表明:2006—2016年间,保护区森林景观发生较大改变,各类斑块占森林面积比均有所增加;核心和边缘斑块为森林主要构成,岛屿、穿孔、连接桥、环、分枝斑块占比则相对较小;保护区森林完整性增强,边缘效应降低,连通性和蔓延性改善;各功能区森林破碎化特征存在差异性,核心区森林破碎化低,而实验区刚好相反;缓冲区森林具有较好的连通性和蔓延性。常绿阔叶林是破碎化最大的植被景观类型,孤岛较多,边缘效应大,应重点保护与恢复。

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
