摘 要 ：在苏北京杭大运河堤引种栽培杉木研究结果表明,粗放经营林分,19a时H12.30m,D1.319.1cm,立木蓄积量224.0m³/hm²,地上部分生物量(干重)达147.12t/hm²,中径材占51.1%,小径材占46.6%;集约管抚林分,13a时H11.90m,D1.315.1cm,立木蓄积量和地上部分生物量分别达204.73m³/hm²和111.05t/hm²,中小径材各占48.4%.广西融水良种杉木,7a时H7.39m,D1.38.9cm,幼林蓄积量达129.64m³/hm²,比同龄本省杉木高1.4倍。

Abstract:It is reported in this paper that Chinese fir(Cunninghamia lanceolata)has been successfully introduced into Northern Jiangsu. In the 19 year old extensively managed plantation on The Grand Canal Bank,the mean height is 12.30 m,its mean DBH 19.1 cm and the stand volume 224 m 3/hm²,and the percentage of medium diameter timber is 51.1% and that of small diameter one 46.6%,its dry biomass above ground is 147.12 t/hm². In the intensively-managed 13-year-old plantation,the height is 11.90 m,the DBH is 15.1 cm,the volume is 204.73 m 3/hm² and its biomass is 111.05 t/hm²,both the percentage of medium and small diameter timber are 48.4%. The plantation in Yongshui,Guangxi is much better than that in Jiangsu,when the plantation is 7 years old,its mean height is 7.39 m,its DBH 8.9 cm and its volume 129.64 m 3/hm²,which are 1.4 times as much as those of the latter at the same age.
