The possibility analysis of natural poplar-birch forest recovery to broad-leaf Korean pine forest through the method of life table in the Xioaxing’an Mountains

Abstract

The basic principle of life table method is described, and the method of tree height instead of tree age in static life table is suggested, and it is also discussed that the possibility of natural poplar-birch forest recover to broad-leaf Korean pine forest on low pitches in the Xiaoxing’an Mountains by this method. If there is no particular situation, Korean pines after high than 5m under natural Poplar-birch forest will basically survive and make their way into dominant canopy accompanied by climax broad-leaf species.
