摘　　要：人类活动已经改变了鞍山大麦科自然保护区的景观格局。本研究基于自然保护区1∶10000土地利用图(1995年勘测)和实地调查资料 ,从斑块、廊道的特征入手 ,分析景观格局变化的原因。结果表明 :决定格局的主体景观类型是水田、林地和天然湿地 ,这三者的面积之和占研究区总面积的85.75 % ,面积较小的斑块呈补丁状散布在整个研究区内。沙地、菜地斑块破碎化较其他斑块明显 ;水田斑块数较多 ;灌丛、阔叶林斑块的破碎化程度较小。廊道在人工斑块中分布较多 ,在自然斑块中分布较少 ,天然湿地中的廊道密度最小。As a result of the disturbance associated with human activities,the landscape pattern of Damaike Nature Reserve in Anshan has been completely changed.By examining the soil utilization map of1995(1:10000)and investigation data,the landscape pattern of the Damaike region was analyzed.Results showed that the principal part of landscape pattern was fixed by paddy fields,forests and natural wetland,the three parts were85.75percent of the area.The other patch types interspersed in the area.The fragmentation of moor land and vegetable land were evidentd,paddy field was most in the region,the corridor types in natural wetlands were forest belt and embankment.Shrub and deciduous forest type had a low degree of fragmentation.Corridors of the area concentrated in paddy fields and unirrigated lands,which were continually activity region by human beings.The density of corridors was small in natural patch type,and the density of corridor was least in paddy fields.
