Analysis and evaluation of ecological landscape pattern of Tianbaoyan Nature Reserve of Fujian

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.
