摘要：从林分生长、生物量、林分结构及土壤养分等方面,对营造于福建邵武的7年生杉木与山杜英不同模式混交林及其纯林进行了研究。结果表明:杉木与山杜英混交林及山杜英纯林具有较高的林分生产力,山杜英纯林(81.9210t/hm2)和杉3∶山1(58.1940t/hm2)混交林生物量分别比杉木纯林高出2.01倍、1.13倍,杉5∶山1(49.7117t/hm2)和杉2∶山1(44.5395t/hm2)混交林生物量,分别比杉木纯林高82.67%和63.66%;杉木与山杜英混交林不仅有利于地力维护,促进杉木生长,而且还能形成较好的林分结构,因此,杉3∶山1混交模式是值得推广的杉阔造林模式。
Different mixed models of seven-year-old Elacocarpus sylvestris and Chinese fir and their pure stands in Shaowu, Fujian were studied by comparing their stand growth, biomass, structure and soil nutrition. The results showed that the pure stands of Elacocarpus sylvestris and its mixed stands with Chinese fir had higher productivity. The biomass of pure Elacocarpus sylvestris stand (81.9210 t/hm 2) and that of the mixed stand of 3 Chinese fir∶1 Elacocarpus sylvestris (58.1940t/hm 2) were 2.01 times and 1.13 times that of pure Chinese fir stand respectively, the biomass of mixed stands of 5 Chinese fir ∶1 Elacocarpus sylvestris ( 49.711 7 t/hm 2) and that of 2 Chinese fir ∶1 Elacocarpus sylvestris (44.5395 t/hm 2) were 82.67% and 63.66% larger than that of pure Chinese fir stand respectively. The mixed stands of Elacocarpus sylvestris with Chinese fir not only help maintain soil fertility and promote growth of Chinese fir but form better stand structure. The mixed stand of 3 Chinese fir ∶1 Elacocarpus sylvestris was a practicable plantation model. 
