Abstract
Soil temperature influences the course of many important processes across the landscape. Nevertheless, the studies performed of it so far have made only small progress in the field of soil physics, as well as in climate studies. This paper systematically summarises the hitherto vaguely arranged pieces of knowledge on the factors affecting the soil temperature and related approaches to spatial interpretation and simulation of soil temperature. Subsequently, two main problems limiting the development of the scientific study of soil temperature have been identified: 1) methodological inconsistencies in the study of soil temperature and factors affecting soil temperature and 2) the low density of points with a representative measurement of soil temperature. Because of the high spatial heterogeneity and the complexity of the relationships of the factors influencing soil temperature, any further studies of soil temperatures must develop in a methodically coherent manner. To achieve this, it seems appropriate to use the concept of elementary process-oriented geo-systems.
