Abstract

This paper aims to investigate the non-stationary relationship between vegetation distribution pattern and topographic and climate conditions in a moist sub-tropical rainforest of Minjiang River Basin in Fujian Province. The HJ-1 satellite image acquired on December 9, 2010 was utilized and NDVI index was calculated representing the range of vegetation greenness. Proper analysis units were achieved through segregation based on small sub-basins and altitudinal bands. Results indicated that the geographic weighted regression (GWR) model was more powerful than ordinary linear least square (OLS) regression in interpreting vegetation-environmental relationship. This paper confirmed that the non-stationary analysis through the framework of GWR could lead to a better understanding of vegetation distribution in subtropical mountainous and hilly region
