Abstract

The invention provides a multilayer soil moisture simulation method and a multilayer soil moisture simulation system. The method comprises the steps of establishing a soil moisture layer equilibrium model, and adjusting the structure of the model by combining a remote sensing technology; acquiring model parameters by the remote sensing technology, and establishing a watershed hydrological spatial information database; and carrying out multilayer soil moisture process numerical simulation by utilizing the adjusted soil moisture layer equilibrium model and the watershed hydrological spatial information database. According to the method and the system, a remote sensing inversion method is coupled with the traditional typical soil moisture layer equilibrium model, so that the model with a clear and definite physical mechanism and simple structure can be established, a certain soil moisture simulation accuracy can be maintained, and spatialization and dynamism of multilayer soil moisture simulation can be realized.

Description

technical field [0001] The invention relates to the field of ecohydrological sciences, in particular to a multi-layer soil moisture simulation method and system. Background technique [0002] Soil moisture is an important part of the water cycle and an important indicator parameter in the fields of hydrology, meteorology and agricultural science research. Changes in soil water content and movement profoundly affect the transformation process of soil internal substances, and play an important role in agricultural production, ecological environment construction and protection through evapotranspiration. In the Global Soil Wetness Project (GSWP), soil water has been discussed and studied as a special topic, and has become one of the important focuses of global change research. Therefore, it is of great practical significance to study the mechanism of soil moisture change and clarify the soil moisture content and migration rules to strengthen regional water resource management,...
