| 摘 要： | 将人工混交林中林木竞争影响空间划分为内、外两圈，采用Hegyi提出的单木竞争指数模型对福建省建瓯东安林场杉木（Cunninghamia lanceolata）一观光木（Tsoongi odenodrum）混交林中林木的种内、种间竞争强度进行分析。结果表明，无论是内圈还是外圈，杉木种内、种间竞争强度均随林木径级的增大而减小；竞争强度顺序为：内圈杉木种内竞争〉内圈杉木观光木种间竞争〉外圈杉木种内竞争〉外圈杉木观光木种间竞争。用模型拟合预测杉木种内、种间的竞争强度，认为杉木在胸径达到36cm之前应采取适当的控制措施。

| Abstract: | The effect space of tree competition in the artificial mixed forest of Cunninghamia lanceolataand Tsoongioden odrumin Dong'an Forestry Farm of Jian'ou,Fujian Province,was divided into two parts,inside radius and outside radius.The interspecific and intraspecific competition intensities of C.lanceolataand T.odrumwere analyzed by using Hegyi's Individual Tree Competition Index model.The results showed that all competition intensities of C.lanceolata,including intraspecific competition and interspecific compet... |
