The Effect of Grain Size on Landscape Indices Analysis of Shijiazhuang

Abstract:

Grain size effect has great impact on landscape patterns quantification analysis.The purpose of this research is to investigate the behavior of six landscape level indices in respond to the grain sizes changing in the scale of province capital city, Shijiazhuang , by using Landsat TM image recorded in 2010. Analyses were conducted for finding out the appropriate grain size for study area. Results showed that: 1) respond type for the value of given landscape indices to grain size changing varied significantly. 2) The grain size range of Area-weighted mean shape index, Mean shape index and Interspersion juxtaposition index are 23m-25m, 25m-30m and 23m-25m. While Shannons evenness index and Shannons diversity index are not sensitive to grain size changing. The Total core area index has not appropriate grain size range. Therefore the suitable grain size for the study area should be 23m-25m.
