摘　　要：以研究区1996、2005年的SPOT卫星影像为原始数据,运用3S技术进行数据处理和信息提取分析,采用景观格局指数分析方法,分析了福建省永安市天宝岩国家级自然保护区的森林景观结构变化。结果表明,从1996-2005年,整体景观斑块平均面积减少了73 690.2 m2,平均斑块周长减少了223.3 m,而各景观组分斑块总周长明显增加。珍贵针叶树种形状指数增加了0.41,破碎度增加了0.051。景观多样性、均匀度指数降低,优势度指数增加。对研究区和相关地区的自然地理、社会经济等研究表明,地形、地貌、土壤和旅游开发等是森林景观变化的关键性驱动力。Based on remote sensing data of Tianbaoyan National Nature Reserve in 1996 and 2005, the forest landscape pattern was processed and analyzed using 3S technology. Index analysis methods for landscape patterns were used for analyzing changes of forest landscape pattern in Tianbaoyan National Nature Reserve. The results showed that the whole patches average area decreased 73 690.2 m2, average perimeter decreased 223.3 m, but the perimeter of each landscape element increased. The shape index of precious conifer species increased 0.41, the fractal dimension of which increased 0.051. Landscape diversity index and evenness index decreased, and dominance index increased. The analyses of physical geography and social economics in the study area and the regions related showed that the most decisive driving forces of landscape changes were terrain, topography, soil and tourism development.
