摘　　要：运用景观空间数据分析软件计算相关景观指数,通过穆棱东北红豆杉国家级自然保护区内景观格局总体情况、斑块面积、周长、总数、分维数、破碎化、均匀度及多样性指数等分析,探讨保护区内森林景观空间格局。结果表明:针阔混交林、阔叶混交林、针叶混交林为保护区主要森林景观;景观要素的斑块面积、周长、数量差异极大;亚乔林及低矮阔叶乔木林景观斑块形状最复杂,且破碎化程度较高,针阔混交林景观斑块形状同样较复杂,但破碎化程度低,且成因不同;保护区总体景观多样性程度较低,景观类型分布不均匀,景观异质性较差。The landscape spatial data analysis software was used to calculate the relevant landscape indices by National Nature Reserve Muling yew overall landscape pattern analysis, patch area, perimeter, total, fractal dimension, fragmentation, evenness and diversity index analysis of protected areas such as forest landscape spatial pattern. The results showed that ： mixed coniferous and broadleaf forest, coniferous forest protected areas were the main forest landscapes; landscape elements such as patch area, perimeter, and number vary greatly; Asia arbor and low broad-leaved trees forest landscape patch shape were the most complex and a higher degree of fragmentation was shown. Conifer landscape patch shape was also more complex, but showed lower degree of fragmentation, and the causes were different ; The overall landscape diversity of the protected areas was low with uneven distribution of landscape types and poor landscape heterogeneity.
