- Abstract:
-
Through measuring the water evapotranspiration by weighing at Dunhuang Mogao Grottoes in the extreme dry area, the factors affecting on evapotranspiration, such as the size of soil grain, salt, water, climate status, the kind of vegetation and etc., were comparatively analyzed, and the nonlinear relationship between the factors and evapotranspiration were found. The evapotranspiration and the factors have a wide nonlinear active mechanism, fitting in the conditions and characters of the existence of the dissipative structure theory. All relative factors are the elements of the evapotranspiration. The integrate action makes evapotranspiring intensity nonlinear state. The intensity of the evapotranspiration is a structure function formed by all factors. When the factors of soil, weather, water, vegetation and etc. fluctuate the cooperating resonance, the dissipative structure will be formed, and the evapotranspiring intensity shows a branching and great variance with a higher or lower nonlinearity. The dissipative structure prevalently exists everywhere in the evapotranspiration system. It is an integrate reflecting a spatio-temporal heterogeneity of evapotranspiring factors. The theory of dissipative structure is testified primarily, reflecting it is suitably applied in the evapotranspiring processes.
