 abstract={The paper presents a method of testing trends in spatial distribution of objects and phenomena. which has been called by the author ,,the spatial concentration method". For those fields of knowledge, where information about trends in spatial distribution of phenomena is important, two meanings of the term ,,concentration" arc used. With respect to functionality it means a mechanism of processes, which lead to Ji versification of concentration of tested objects or phenomena in space. With respect to the structural aspect, the term ,.concentration" is understood as description of certain conditions of the tested spatial system, i.e. conditions of higher or lower concentration of the system elements. This paper focuses on concentration with respect to the latter case. The proposed method of spatial concentration is a tool, which allows for wide research investigations. It has been assumed that concentration is specified with respect to a reference function, which is selected according to the objective of investigations. Therefore it is possible to investigate various aspects of trends in distribution of phenomena. It should be stressed that the proposed method is of general nature, in a sense that it also covers other methods of investigations, which have been based on measures of concentration; the proposed method also allows for searching for trends in spatial distribution of phenomena and objects. The algorithm of determination of spatial concentration, presented in a simple form, is the base for software development and for automation of investigations.},
