摘要：从林分生长、生物量、空间分布格局及土壤养分等方面 ,对营造于福建邵武的 5年生杉木与马褂木、檫树不同模式混交林及其纯林进行了研究。结果表明 :杉木与马褂木、檫树混交林及马褂木、檫树纯林具有较高的林分生产力 ,马褂木纯林 (91.932 t· hm-2 )和杉 2∶马 1(4 5 .2 32 t·hm-2 )混交林生物量 (烘干 )分别是杉木纯林的 4 .5 5倍、2 .2 4倍 ;杉 3∶马 1(36.12 0 t· hm-2 )和杉5∶马 1(34 .2 92 t· hm-2 )混交林生物量 ,分别比杉木纯林大 78.96%和 69.90 % ;檫树纯林生物量(60 .10 5 t· hm-2 )是杉木纯林的 3.31倍 ,杉 2∶檫 1(32 .4 2 6t· hm-2 )、杉 3∶檫 1(2 8.635 t·hm-2 )和杉 5∶檫 1(2 5 .82 3t· hm-2 )混交林 ,分别比杉木纯林大 78.5 4 %、5 7.67%和 4 2 .18%。杉木与马褂木、檫树混交林不仅有利于维护地力 ,促进杉木生长 ,而且可形成较好的林分结构 ,杉 2∶马 (檫 ) 1带状混交模式是值得推广的杉阔造林模式。
From the viewpoints of tree growth,biomass,spatial distribution pattern and soil fertility,the pure and mixed stands of 5 year old Cunninghamia lanceolata and Liriodendron chinense and Sassafras tsumu grown in Shaowu of Fujian Province were studied.The results showed that the C.lanceolata L.chinense,C. lanceolata S.tsumu mixed stands and the pure stands of L.chinense ,and S.tsumu have higher productivity.The biomass of pure L.chinense stand was 91 933 t·hm -2 ,and the mixed stand(C.lanceolata∶L.chinense=2∶1)was 45 32 t·hm -2 ,which are 4 55 times and 2 24 times that of pure C.lanceolata stand.The biomass of mixed stands of C.lanceolata and L.chinense in the ratio of 3∶1 and 5∶1 were 36 1201 t·hm -2 and 34 2920 t·hm -2 respectively,which were 78 96% and 69 90% higher than that of pure C.lanceolata pure stand.The biomass of pure S.tsumu stand was 60 105 t·hm -2 ,which was 3 31 times that of the C.lanceolata Pure stand.The biomass of mixed stands of C.lanceolata and S. tsumu in the ratio of 2∶1,3∶1 and 5∶1 were 32 426 t·hm -2 ,28 635 t·hm -2 and 25 822 t·hm -2 ,which were 78 54%,57 67% and 41 18% higher than that of the C.lanceolata pure stand.The mixed stand of C.lanceolata with L.chinense and S.tsumu could form better stand structure as well as benefits the soil fertility and promotes the growth of C.lanceolata.The authors hold that the mixture pattern of C.lanceolata and L.chinense in the ratio of 2∶1 is a good afforestation pattern and worth to be extenuated .
