Abstract
There is a close relationship between climate system and ecological system. Apparently, air temperature on ecosystem , to great extent, affects the physiological and biochemical processes of the ecology, which influences the development of the ecological system, so studying the relationship between air temperature and the ecological system is very important. In this paper, the ecological system (i.e. oasis) is assumed to be all covered by plants, in terms of both Charney's desert theory(Charney,1975) and Pan et.al.'s thermal energy balance method (Pan et.al.,2001), we theoretically build a climate dynamical model, With which air temperature on underlying ground(i.e. vegetation) is calculated separately in consideration of elements(the underlying ground's albedo, resistance of stomata of plant and solar radiation flux). It is shown that changes among these elements can produce different changes of air temperature on the underlying ground, which will affect the development of ecology in return, leading to further understanding relationship between climate and oasis. And further research of these questions is on the way.
A Climate Dynamical model on Oasis Development
