摘要
基于地统计分析理论,选取香农多样性指数和斑块密度2个景观格局指数,对南京钟山风景区不同幅度下的景观格局进行分析,选出南京钟山风景区的最佳景观格局研究尺度,并在最优尺度下,对2个景观指数进行插值分析,将单一的景观指数转换为丰富的面状数据,进而研究钟山风景区景观指数的空间分布特征。结果表明:南京钟山风景区地类景观的最佳分析尺度是600 m,在该尺度下,钟山风景区的景观多样性指数空间分布分为3个较高值区域和1个较低值区域,斑块密度指数则呈现环状分布。
The landscape pattern of Nanjing Zhongshan scenic spot was analyzed under different scales based on the geo-statistical analysis theory and by taking Shannon Diversity Index and Patch Density as landscape pattern indexes.The optimal scales were selected to study the landscape pattern of Nanjing Zhongshan scenic spot,and the spatial distribution characteristics of the landscape pattern of Nanjing Zhongshan scenic spot was studied and the single data of the landscape indexes were transferred to the rich polygon data by means of interpolation analysis of the two landscape indexes under the best scales.The results showed that the best scale for the landscape pattern analysis on Nanjing Zhongshan scenic spot was 600 m,under which the spatial distribution of the landscape diversity index could be divided into three high value regions and a low value region,and the patch density index showed circular distribution.
