PRINCIPAL PROBLEMS IN REGARD TO CLIMATE I N FOREST SITE SCIENCE AND FOREST ECOLOGY

A combination of the terms ''atmosphere and soil'' is better than ''cl imate and soil''. Unfortunately, forest site science relates climate t o woodless terrain, soil to forests. Methodically favourable is the di stinction between ''basis climate'' (Basisklima, site without forest) and ''state climate'' (Zustands-klima, site with forest). Weather stat ions do not measure the basis climate. Furthermore, problems connected with the selection of climatic elements, the measuring errors and the fertility of climate are discussed.
