Abstract: This paper,by analysing the maps of physical conditions,studies the theories and methods of the combined analysis of isoline maps and quality feature maps.Deep researches have been made into the samplins methods and size and arrangement of samples of simulating geographycal phenomena on the maps of different properties and expressions.Especially,the fuzzy evaluation and fuzzy cluster have been introduced into the information acquisition and processing.Trial for regions of agricultural climate types has proved the result is correct and is able to be used in practice also.It shows that fuzzy mathematics has a unique advantage in the combined analysis of maps of different properties and expressions.
