湄潭县城规划区景观指数的粒度效应分析
Landscape indices with sensor grain size changes in Meitan County, China
摘要
Abstract
Based on the aerial remote sensing image of Meitan in 2010 and the thematic mapper (TM) image of Meitan in 2007, the grain size effect and fitted functions of 15 selected landscape pattern indices, which were divided into five categories of amplitude-accreting: stable decreasing and then stable, undulatory decreasing and then stable, undulatory decreasing, and anomalistic changing, from Meitan County were analyzed with ArcGIS 9, Fragstats 3.3 and SPSS software. Results showed that for the range of the grain size, most of the selected indices had an effect on grain size and there response curves could be fitted with linear function, quadratic function, cubic function, inverse function, power function and logarithmic function. To research the landscape of Meitan County, a suitable range for grain size when computing and analyzing landscape indices was 2-10 m with an aerial remote sensing image and 55-65 m with a TM image. To improve the results, high-resolution image data could be utilized to analyze the landscape pattern of Meitan County. [ Ch, 2 fig. 2 tab. 19ref.]关键词
