摘　　要：自１９９１ 年开始分别对浙江安吉和福建建阳的两种类型的毛竹纸浆林的丰产结构进行了４ 年的定位观察研究。研究结果表明：对于毛竹纸浆纯林的丰产结构，以竹林密度为３０００ 株／ｈｍ ２、林分年龄结构组成为１ 度竹∶２ 度竹＝ ７∶３ 等林分结构因子组合的竹林的生产力最高，其新竹度产量高达３１．１ｔ／ｈｍ ２；并根据新竹产量与竹林密度和林分年龄组成的非线性相关关系，建立了新竹产量的预测模型。对于毛竹—阔叶树纸浆混交林，影响其生产力最重要的林分结构因子是树种组成，即毛竹与阔叶树的混交比，其次是混交林中的立竹量，其中以混交比∑Ｄ竹２∶∑Ｄ树２＝ ８∶２、林分立竹量为２１００ 株／ｈｍ ２ 等林分结构因子组合的毛竹—阔叶树纸浆混交林的生产力最高，其新竹度产量达２２．８ｔ／ｈｍ ２。The high-yield forest structures of two types of Moso bamboo ( Phyllostachys pubescens ) pulp stands have been studied in Anji, Zhejiang Province and Jianyang, Fujian Povince respectively from 1991 to 1995. The factors of bamboo stands structure,including bamboo stand density, culm age component, and bamboo and tree component etc. have been researched. The results have shown that it is the best high-yield structure for Moso pure stands to keep bamboo stand density 3,000 standing culms per ha. and make the culm age component of bamboo stands as 1- and 2-year old: 3- and 4-year old = 7:3. The bamboo pulp stands keeping the above-mentioned high-yield structure will produce the highest productivity, i.e., the new culm yield reachs 31.1 t·hm -2 per Du *. The model of calculating new culm yield has also been established depending on the nonlinear relationship between new culm yield and bamboo stand density, culm age component. The most important factor influencing the productivity of Moso and broad leaved tree mixed stand in structure factors is the bamboo and tree component, and the second is the bamboo standing density. In this trial, the best combination of structure factors is to make ∑D B 2∶∑D T 2 =8∶2 and keep bamboo stand density 2100 standing culms per ha. This kind of Moso broad leaved tree mixed stand will produce 22.8 t·hm -2 per Du of the new culms.
