摘要
根据景观生态学原理,在RS、GIS软件支持下提取景观斑块的数量、面积、周长等信息,对福建省天宝岩国家级自然保护区的景观生态格局进行分析;并利用层次分析法,选取多样性、稀有性、自然性、代表性、面积适宜性、人类干扰、稳定性等7项指标对该自然保护区进行景观生态评价。结果表明:常绿阔叶林、常绿针叶林和常绿针阔混交林是研究区的主导景观类型且破碎化程度低,植被的保护较完整;居民点的斑块数多,孔隙度最大,对景观类型的形成有主要的影响;景观类型多样性以类型斑块数最大,类型面积最小。福建省天宝岩国家级自然保护区景观生态质量的综合评价指数为0.819,说明该自然保护区的景观生态质量较好。
Based on the principles of landscape ecology and supported by RS and GIS technology,data on the number,area and perimeter of landscape patches in Tianbaoyan Nature Reserve（a national nature reserve） of Fujian Province were extracted and used to analyze the landscape pattern of the protected area.Then by using AHP method along with multiplicity,rareness,naturalness,representation,area feasibility,human disturbance and stability indices,a comprehensive landscape evaluation was performed.The study reveals three dominant vegetation types in the area ― evergreen broadleaf forest,evergreen coniferous forest and evergreen conifer-broadleaf mixed forest.There is a low degree of landscape fragmentation in the area,indicating that vegetation in the area is somewhat under sound protection.Residential patches are in the greatest number with large landscape porosity,which has a major effect on landscape formation in the study area.The diversity of landscape is highest at the patch-scale and lowest at area-scale.The integrated landscape ecological quality evaluation of Tianbaoyan Nature Reserve is 0.819,implying that the ecological quality of the study area is still sound.
