对雷州半岛5年生11种桉树无性系的林分生长量、生物量和生产力进行了研究。结果表明：11种无性系间胸径、树高、单株材积均差异极显著,林分蓄积量分布在114.57~206.75 m3.hm-2,其大小排序为：DH201-2〉LM1〉DH32-22〉LH1〉GL9〉EC33〉EC48〉U6〉TM3〉EC42〉EC40;11种桉树无性系林分各组分生物量都以干的最大,叶的最小;DH32-22、GL9、LH1、EC48、EC48、EC48、TM3和U6各组分排序为干〉根〉皮〉枝〉叶,DH201-2、EC33和LM1各组分排序为干〉根〉枝〉皮〉叶;11种桉树无性系林分生物量大小排序为：LM1〉DH201-2〉EC33〉LH1〉DH32-22〉GL9〉U6〉EC48〉EC42〉EC40〉TM3;11种桉树无性系林分生产力大小排序为：DH201-2〉LM1〉EC33〉LH1〉DH32-22〉GL9〉U6〉EC48〉EC42〉EC40〉TM3;从生长量、生物量和生产力的角度看,DH201-2、DH32-22、EC33和LM1的林分蓄积量、林分生物量和林分生产力较大,比较适合作为能源林树种在雷州半岛种植;U6、EC48、EC42、EC40和TM3生长较为缓慢,生物质转化效率不高,不适合作为能源林品种。
對雷州半島5年生11種桉樹無性繫的林分生長量、生物量和生產力進行瞭研究。結果錶明：11種無性繫間胸徑、樹高、單株材積均差異極顯著,林分蓄積量分佈在114.57~206.75 m3.hm-2,其大小排序為：DH201-2〉LM1〉DH32-22〉LH1〉GL9〉EC33〉EC48〉U6〉TM3〉EC42〉EC40;11種桉樹無性繫林分各組分生物量都以榦的最大,葉的最小;DH32-22、GL9、LH1、EC48、EC48、EC48、TM3和U6各組分排序為榦〉根〉皮〉枝〉葉,DH201-2、EC33和LM1各組分排序為榦〉根〉枝〉皮〉葉;11種桉樹無性繫林分生物量大小排序為：LM1〉DH201-2〉EC33〉LH1〉DH32-22〉GL9〉U6〉EC48〉EC42〉EC40〉TM3;11種桉樹無性繫林分生產力大小排序為：DH201-2〉LM1〉EC33〉LH1〉DH32-22〉GL9〉U6〉EC48〉EC42〉EC40〉TM3;從生長量、生物量和生產力的角度看,DH201-2、DH32-22、EC33和LM1的林分蓄積量、林分生物量和林分生產力較大,比較適閤作為能源林樹種在雷州半島種植;U6、EC48、EC42、EC40和TM3生長較為緩慢,生物質轉化效率不高,不適閤作為能源林品種。

Growth, biomass and productivity of 1 1 5 - year - old eucalypt clones stands in Leizhou Peninsula were studied. The results showed that diameter at breast height, tree height and individual volume of 11 euca- lypt clones between each other were significantly different. The order of stand volume was： DH201-2 〉 LMI 〉 DH32-,, 〉 LH1 〉 GL9〉 EC~〉 EC4s〉 U6〉 TM3〉 EC42〉 EC40 .Thebiomassoffive components changed different- ly with stem - wood having the highest biomass and leaves the lowest. The order of various components＇ biomass of DH32-22, GL9, LH~, ECa, EC4s, EC4s, TM3 and U6 was stem - wood 〉 roots 〉 bark 〉 branch- es 〉 leaves and stem - wood 〉 roots 〉 branches 〉 bark 〉 leaves for DH20~-2, EC33 and LM1. The order of stand biomass and productivity of 11 eucalypt clones were LM1〉 DH20~-2〉 EC33〉 LH1〉 DH32-=〉 GLg〉 Us〉 EC4s〉 EC42〉 EC40〉 TM and DH201-2〉 LM~〉 EC33〉 LH,〉 DH32-~〉 GL9〉 Us〉 EC4s〉 EC42〉 EC40〉 TM3 respectively . Growth, biomass and productivity of DH~oL-2, DH32-,,, EC33 and LM~ stands were higher than those of others＇, which could be used for fuel forest. Us, ECa, EC42, EC,o and TM3 were not suitable for fuel forest because of their low growth and biomass conversion efficiency.
