Analysis model is a description of objective things or phenomena.Model is one of the studied objectsabstract。The objective thing or phenomenon is a multifactor complex.There is a relationship of interdependence and mutual restriction between factors, which is usually a complex nonlinear relationship.
In order to analyze the interaction mechanism and reveal the internal laws, a model can be designed to represent the research object according to theoretical derivation, or analysis of observation data, or based on practical experience.The model reflects the essence of the object and omitsRamifications, is the substantial description and some degree of simplification of the studied object, which is intended to facilitate analysis and research. The model can be a mathematical model orphysical model 。The former is not subject toSpace and timeThe limitation of scale, which can be compressed or extended, can be simulated by computer, so it is widely used;The latter is based onsimilarity theory To build the model.In geography, material, energy andinformation transferMany analytical models have been established in the research of and transformation.It is an effective scientific method to analyze by means of models.
