The concept of topographic index (TI), for characterizing the likely distribution of variable source areas within a watershed, has been successfully incorporated into some land-surface processes parameterizations and climate models. Representing the spatial distribution regime of TI accurately and simply is a crucial issue for those topography-based land- atmosphere interactions studies. In this paper,...
Spatial heterogeneity with scale multiplicity inherent is the most fundamental characteristic of all landscapes, thus multi-scale analysis is imperative for understanding the structure, function and dynamics of landscapes. Lacunarity index and wavelet analysis were employed in this study to determine landscape heterogeneity and multi-scale spatial patterns of Hotan Oasis by using RS and GIS techniques...
