| 摘 要： | 本文以闽江流域为研究区域,以LandsatTM遥感图像为主要信息源,以Erdas Imagine图像处理软件作为空间信息处理工具,采用斑块平均面积、形状指数、分维数、香农多样性指数、均匀度指数和优势度指数等指标,对闽江流域森林景观格局进行了研究.研究结果表明:闽江流域景观的主要斑块类型为杉木林、松林和阔叶林.分维数表明竹林与经济林受人类干扰大,斑块形状简单;阔叶林与松林受人类干扰小,斑块形状复杂.香农多样性指数(SHD I)表明景观异质性较高的特点,均匀度指数(SHEI)则表明景观中有一定的优势类型,以杉木林、阔叶林和松林等景观类型占优势. |

| Abstract: | In the support of the RS and GIS technology,with the help of RS tool of Erdas Imagine based on the information from Landsat TM image,six indices were put forword to analyze the patterns of forest landscapes in Minjiang watershed.These indices(included) mean matrix area,contour index,fractal dimension,Shannon-weiner diversity index,Shannon-weiner evenness index,dominance index.Fractal dimension indicated bamboo groves and economic forest were mainly managed by human,the patch shape was simple.Pine forests and broadleaved forests were less managed by human,the patch shape was complicated.The results showed that the forest landscape were mainly Chinese fir forests,pine forests and broad-leaved forests.SHDI showed that the landscape(heterogeneity) was high;while SHEI showed that the proportion of each landscape type was very different,Chinese fir forests,pine forests and broad-leaved forests were the dominant landscape type. |
