摘要
利用航测真彩色图像,在GIS软件MAP/INFO支持下提取济南植物园景观斑块信息,从景观总体特征、斑块面积、斑块周长、斑块数和形状指数、多样性指数、分维数、均匀度指数、破碎度指数等角度对其景观格局和破碎化程度进行了分析和评价。从总体来看,破碎化指数较小,景观具有较好的完整性。
The landscape pattern and fragmentation degree of Jinan Arboretum were analyzed and evaluated based on GIS software MAP/INFO by utilizing colorful map of plane and the fragmentation were analyzed after studying the overall characteristics, patch area, patch circumference, patch numbers and shape index, diversity index, fractal dimension, evenness index, and fragmentation index. Generally speaking, the less the fragmentation index is, the better the completeness of the landscape is.
