Abstract: The importance of the land-atmosphere interaction studies over the living environment in the arid areas is presented. Meanwhile the system of model parameterized and measuring index as well as the measuring field and results have also been introduced. The measuring results of the land-atmosphere water-heat exchange process in the non-watering plot in Shapotou desert area, Ning Xia Province, in high-cold meadow of Qing Hai Province, and in the irrigating agricultural fields in Tarim Basin, Xin Jiang province are discussed. Through the comparison with the actual measuring data, the model is proved to successfully simulate the land-atmosphere interaction processing. The land-atmosphere interaction rule in various land surfaces in the arid areas can provide scientific foundation for the optimizing use of local water-heat resources.
