- Abstract:
-
Landscape scaling effect becomes one of the hottest subjects in landscape ecology. We can study the change of landscape pattern by changing the scale. Based on landscape ecology theory and the support of software ArcGIS, Fragstats 3.4 and GS+, using Hongsipu 2015 TM remote sensing image, selecting landscape diversity index and patch density index, using semivariogram analysis and kriging interpolation, we analyzed landscape pattern index response to scale change. The results of analysis indicate that:the results differed at different scales we had chosen, and the spatial heterogeneity and spatial pattern of landscape diversity and patch density had changed; (2) the landscape diversity and patch density depended on spatial scale; with the increasing scale, the spatial heterogeneity caused by spatial autocorrelation increased; (3) the sizes of the indexes have the relationship with human activity, the greater the land use intensity was, the larger the index became; (4) with the increasing scale, the local pattern of spatial pattern was gradually concealed, and the macroscopic rule was prominent; (5) overall consideration, the scale of 3 km is the perfect choice.
