Abstract :
Different ecological and environmental information can be revealed at different scales. This method reveals the temporal and spatial patterns of the ecological capacity of the Li River Basin (LRB) at three different scales including perpixel, county and regional levels over past 20 years. Although the total ecological capacity at regional level doesn´t exhibit any sign of ecological deficit, the pixel-based results reveal that the ecological deficit concentrated in part of Guilin County, Xing´an County, Yangshuo County and the surroundings of Li River. The deficit had been expanding from these regions to their surroundings during the period of 1991 through 2013. The results offer detailed and unique information to assist with decisions and strategies associated with further regional development and ecological conservations.
