【摘要】 为了深入了解笃斯越桔的生长状况,对长白山东坡落叶松林下笃斯越桔群落进行了调查研究。结果表明:长白山东坡落叶松林下笃斯越桔的生长密度最小为36株/m2,最大为145株/m2,平均83株/m2。调查样方平均基径为2.61～4.71mm,平均高度为33.36～59.50cm。基径径级分布2～4mm最多,其次是4～6mm和<2mm,6～8mm最少,8～10mm径粗越桔鲜有见到。高度级分布30～40cm、40～50cm、50～60cm高度间的越桔所占比重最多,其次是20～30cm、60～70cm、70～80cm高度的越桔,再次是10～20cm和80～90cm,<10cm越桔很少,90～100cm高度的越桔非常少见。更多还原

【Abstract】 In order to deeply understand the growth status of Vaccinium uliginosum,Vaccinium uliginosum community under Larix olgensis forest in eastern slopes of Changbai Mountain were investigated.The results indicated that the minimum growth density of Vaccinium uliginosum was 36 plants/m2 under Larix olgensis forest in eastern slopes of Changbai Mountain,with the maximum 145 plants/m2 and the average 83 plants/m2.The average base diameter of investigated quadrat was from 2.61 mm to 4.71 mm,the average height was from 33.36 cm to 59.50 cm.The most base diameter-class distribution was from 2 mm to 4 mm,secondly was from 4 mm to 6 mm and less than 2 mm,the least was from 6 mm to 8 mm,from 8 mm to 10 mm was rare.The most proportion of height-class distribution was from 30 cm to 40 cm,from 40 cm to 50 cm and from 50 cm to 60 cm,secondly was from 20 cm to 30 cm,from 60 cm to 70 cm and from 70 cm to 80 cm,thirdly was from 10 cm to 20 cm and from 80 cm to 90 cm,little was less than 10 cm,from 90 cm to 100 cm was rare.更多还原
