Scale Effect of Landscape Pattern of Nanjing Zhongshan Scenic Spot Based on Statistic Analysis

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 600m, 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.
