| 描述 | In the European Alps the importance of forests as protection against ava- lanches and soil erosion is becoming ever clearer with the continuing increase in population and development of tourism. The protective potential of the moun- tain forests can currently only be partially realised because a considerable propor- tion of high-altitude stands has been destroyed in historical times by man‘s extensive clearing ofthe forests. The forests still remaining are of limited effec- tiveness, due to inadequate density of trees and over-maturity. Considerable efforts, however, are now being made in the Alps and other mountains of the globe to increase the high-altitude forested area through reforestation, to raise depressed timberlines, and to restore remaining protection forests using suit- able silvicultural methods to their full protective value. This momentous task, if it is to be successful, must be planned on a sound foundation. An important prerequisite is the assembly of scientific facts con- cerning the physical environment in the protection forest zone of mountains, and the course of various life processes of tree species occurring there. Since the introduction of practical field t |
