Abstract

The 1:50,000 Digital Elevation Model (DEM) data of Longitudinal Range-Gorge Region (LRGR), meteorological observation data from the station establishment to 2010, hydrological observation data, Normalized Difference Vegetation Index (NDVI) and Net Primary Productivity (NPP) products of MOD13 and MOD17 as well as 1:1,000,000 vegetation type data were used. Based on ANUSPLIN spline function, GIS spatial analysis, wavelet analysis and landscape pattern analysis, regional differentiation characteristics and main-control factors of hydrothermal pattern, ecosystem structure and function in this region were analyzed to reveal the effects of terrain pattern on regional differentiation of eco-geographical elements. The results show that : influenced by terrain pattern, moisture, temperature and heat in LRGR have shown significant distribution characteristics. Under the combined effect of zonality and non-zonality laws with “corridor-barrier” function as the main characteristic, special spatial characteristics of eco-geographical regional system in LRGR is formed
