Abstract
It is not to mention that the meteorological phenomena are very significant environmental factors for the life of plant, but it is a rather difficult problem to clarify in what extent the factors act the role in the growing process of plant. The phytometer method, proposed as one of the methods of environmental analysis by CLEMENTSet al., does not yet work in practice, since the method is nothing more than one giving the plasiticity of plant through a consideration that “ the environmental variation reflects on the function and formation of plant, ” and then is not available for the analysis of practical process.
The present author presents a new met h od of environmetal analysis, on the basis of the same consideration as in phytometer method, and demonstrates the through practicability of the new method for analysis for the actual cases with bamboo forest and pasture community. For example, it is clarified that the precipitation amount in June plays the major role as the first order factor in bamboo forest at Toyama Village in Chiba Pref., Japan, where was chosen as one of object sites in the present investigations. While, the thickness of surface soil is pointed out as the first order factor in the case of pasture community at Asama Village in Nagano Pref.
