CHANGE OF THE PLANT COVER AND FOREST REGENERATION ON THE CLEAR CUTTING AREA IN PINE FOREST OF WESTERN KHENTEI

Abstract

In article show results of study and an estimation of change plant cover in pine forest of the western part Khentei upland Mongolia under influence of anthropogenous and natural factors. It is established, that after removing the main part of the stand 34 years ago in the taiga pine forest herb-fireweed-reedgrass (on the clear cutting area) of the Western Khentei floristic composition rate was 67.8% and coenotic rate-30.2% in comparision native forest. The comparative analysis showed, that the considered trial areas have reduction of occurrence and plant covering of taiga forest species and increase of specific variety forest meadow and steppe and forest steppe species.
