通过2012—2013年顺昌县大历镇阔叶树保留木资源调查分析,结果表明：不同径阶阔叶树保留木的株数分布整体上呈“L”形,每个径阶阔叶树保留木达200株以上的主要分布于径阶为6~14 cm 之间,共有1499株,占总数的73.37%；径阶16 cm以上保留的株数仅占总数的26.63%。阔叶树保留木中间层中径木,共有1978株,占总数的96.82%；上层大树仅65株,仅占总数的3.18%。不同径阶的阔叶树保留木蓄积量分布基本上呈正态分布,径阶5~14 cm阔叶树保留木蓄积量为63.82 m3,占总保留木阔叶树蓄积量187.29 m3的34.08%；径阶16 cm 以上的阔叶树保留木蓄积量为123.47 m3,占总保留木阔叶树蓄积量的65.92%,是径阶5~14 cm 阔叶树保留木蓄积量1.93倍。阔叶树中间层中径木蓄积量为146.08 m3,占总蓄积量的78%；上层大树蓄积量为41.21 m3,蓄积量占总数的22%。阔叶树保留木胸径5~14.9 cm共需补偿3191元,胸径15 cm 以上需补偿12347.00元,大历镇阔叶树保留木共需补偿15538.00元。阔叶树保留株数平均值为138.6株 hm-2,阔叶树蓄积量保留平均值为12.75 m3 hm-2,阔叶树保留木不炼山造林成本从造林至郁闭前需投资27000元 hm-2。%Resources of residual trees for broadleaved-trees at different diameter grades in Dali Town of Shunchang County were analyzed from 2012 to 2013.Result shows that:distribution for number of trees of residual trees for broadleaved-trees at different diameter grades appears an“L”type.Residual trees (above 200 trees)of broadleaved-trees at each diameter class mainly distributed 6-14 cm,a total of 1 499 trees,constitute 73.37% of the total;the number of reserved trees only constitute 26.63% of the total above 16 cm;middle diameter wood in middle layer of broadleaved-trees,there are 1 978 trees,constitute 96.82% of the total;there are only 65 trees in the upper layer which constitute 3.18%.Distribution of stock volume of residual trees for broadleaved-trees at different diameter grade is substantially normal,the growing stock of residual trees for broadleaved-trees is 63.82 m3 with the diame-ter grade being 5-14,which constitute 34.08% of the growing stock (187.29 m3 );the growing stock of residual trees for broadleaved-trees are 123.47 m3 with the diameter grade being above 16 cm,which constitute 65.92% of growing stock for broadleaved trees for residual trees,which is 1.93 times as large as growing stock for broad-leaved-trees.Growing stock of middle diameter in the middle layer for broadleaved-trees is 146.08 m3 ,constitute 78% of the total stock volume ;the growing stock of upper trees are 41.21 m3 ,which constitute 22% of the total accumulation accounts.DBH of the residual trees for broadleaved-trees is 5-14.9 cm,compensation totaling 3 191 Yuan;DBH (more than 15 cm)of the residual trees for broadleaved-trees required to compensate 12 347.00 Yuan;broadleaved-trees in Dali Town will compensate totaling 15,538.00 Yuan.The mean value of reserved number of trees for broadleaved-trees are 138.6 trees hm-2;the reserved mean value of broadleaved-trees is 12.75 m3 hm-2 , the cost of non-slash burning afforestation for broadleaved-trees from afforestation to canopy needs an investment of 27 000 Yuan hm-2 .
