In the geographic research, for example classification and mathematical modelling, division of the research area onto network of basic spatial units (quasi-homogenous) is applied. An often applied is division of research area onto regular geometric units. The question, which has not been solved yet, is a determination of an optimal size of a basic spatial units. Two objective methods of the research area division into the basic units network are presented in the paper. Górna Wilga watershed has been used for comparing effects of the watershed division on the basic fields, which are obtained from the geometrical and geostatistical methods. Application of the geometrical methods enables to obtain the optimal basic field size from in-formation on dimension of research area. This method can be used in the investigation in the regional scale, where researches and results are more generalised. Application of geostatistical methods (semivariance and nearest-neighbour analysis) enables to obtain the celi size of the quasi-homogenous fields' network from the spatial variability of environmental conditions and from the measure points localisation. Geostatistical methods can be used in the investigations on small areas (for example small watersheds), where the greater detailing of data and results is required.
