Description :
This discussion results in new understanding on eco-geographic regions and their boundaries, especially on gradual changes of natural conditions between eco-geographic regions. It clarifies differences and causes of the differencies for the results. New concepts of tropical, annual tropical, true tropical and tropical fluctuating zone are formed to understand tropical area. Based on the indexes of climate, vegetation and soil, boundaries of tropical, annual tropical, true tropical and tropical fluctuating zone of the study area are established. The tropical fluctuating zone explains different locating of different researchers. This paper also puts forward a new method to display boundary for eco-geographic regions.
