  • Life form, flower color, flowering and seed-ripening seasons of 59 alpine plants in Paeknokdam, the crater of Mt. Halla, were investigated in order to obtain the information about ornamental potentials of alpine plants. Life form spectrum of alpine plants are characterized by a high percentage of hemicryptophytes (67.8%). This result was similar to those of other alpine plant communities. Flowering season of alpine plants was July to August and seed-ripening season was August to September. Flower color of these alpine plants was dominated by white (27%), blue (22%) and yellow (20.3%).

  • Mt. paektu(altitude 2,749.6m) is ecologically important because successional processes following volcanic eurption are quite clear. We investigated plant communities with altitude know vertical distribution of plant vegetation on the north-western slope of Mt. paektu was divided into five parts; the pine-hardwood forest zone(600∼1,000m alt.), the lower coniferous forest zone (1,000∼1,500 m alt.), the upper coniferous forest and birch forest zone(1,500∼2,000 m alt.), the alpine shrub zone(2,000∼2,500 m alt.) and the alpine meadow zone(2,500∼2,749 m alt.). In particular, the alpine zone was divided into alpine shrub and alpine meadow zones and distributed up to 2,500m alt. these results reflet the adaptations of these shrubs at this altitude. But these shrubby communities disappeared on the alpinemeadow zone. In the alpine meadow zone above than 2,500m alt., some meadows, papaver radicatum var pscudoradicatum. bistorta ochotensis, chrysathemum zawadskii var. latilobum etc., were occured.

  • The alpine grassland vegetation at the northwest slope of Mt. Paektu were investigated by Penound- Howard's cover-degree method. The floristic composition of the alpine grassland from 2,100m altitude to the top of mountain were 35 species, 1 subspecies, and 6 varieties, and most of the plants were short p e r e ~ i a l herbs and shrubs. The dominant species of the vegetation distributed along to altitude were Rhododendron aureum (2,100-2,20Om), Dryas octopetala var. asiatica(2,200-2,30Om), Dryas octopetala var. asiatica(2,300-2,40Om), Rhododendron aureum- Rhododendron redowskianum(2,400-2,50Om), and Rhododendron redowskianum(2,500- 2,58Om), respectively. Characteristics of the shrub plants which settled in alpine grassland showed uniform low height(3-15cm), creeping stem and evergreen leaf. Life form of the plants were 29 species of Hemicryptophyte, 8 species of Chamaephyte, 1 species of Geophyte, and 5 species of Phanerophyte. (Key words : Alpine grassland, Mt.
