以粤北冰雪灾害损毁杉木（Cunninghamia lanceolata）林套种阔叶树形成的混交林为对象，采用标准地调查法，研究人工干预形成针阔混交林的生长情况及其林分结构特征。结果表明，经过5 a的人工修复，已形成良好的杉木阔叶树混交林，其中，萌芽杉木平均胸径达到4.41~5.48 cm，木荷（Schima superba）、黎蒴（Castanopsis fissa）、火力楠（Michelia macclurei）、深山含笑（Michelia maudiae）、樟树（Cinnamomum camphora）平均胸径可分别达到2.72，6.03，2.59，1.75，3.30 cm。在水平分布格局上，9个样地属随机分布，6个样地呈均匀分布，无样地呈聚集分布；树种混交度呈弱度、中度混交；各阔叶树相对于杉木的种间竞争优劣顺序依次为黎蒴、木荷、樟树、火力楠、深山含笑。不同配置的阔叶树种所形成林分的空间结构特征没有明显差异。
以粵北冰雪災害損燬杉木（Cunninghamia lanceolata）林套種闊葉樹形成的混交林為對象，採用標準地調查法，研究人工榦預形成針闊混交林的生長情況及其林分結構特徵。結果錶明，經過5 a的人工脩複，已形成良好的杉木闊葉樹混交林，其中，萌芽杉木平均胸徑達到4.41~5.48 cm，木荷（Schima superba）、黎蒴（Castanopsis fissa）、火力楠（Michelia macclurei）、深山含笑（Michelia maudiae）、樟樹（Cinnamomum camphora）平均胸徑可分彆達到2.72，6.03，2.59，1.75，3.30 cm。在水平分佈格跼上，9箇樣地屬隨機分佈，6箇樣地呈均勻分佈，無樣地呈聚集分佈；樹種混交度呈弱度、中度混交；各闊葉樹相對于杉木的種間競爭優劣順序依次為黎蒴、木荷、樟樹、火力楠、深山含笑。不同配置的闊葉樹種所形成林分的空間結構特徵沒有明顯差異。

Based on surveying typical sample plots of the mixed plantations ofCunninghamia lanceolata and broadleaf tree by artificial restoration from pure forest ofC. lanceolata damaged by snow and ice disaster in northern Guangdong, the growth and stand structure characteristics of the mixed forest were analyzed. The results showed that five years later, superior mixed plantations were established. The diameter at breast height(DBH)ofC. lanceolata ranged from 4.41 to 5.48 cm, and those ofSchima superba, Castanopsis fissa, Michelia macclurei, Minnamomum maudiaeandCinnamomum camphora were 2.72, 6.03, 2.59, 1.75 and 3.30 cm, respectively. In terms of horizontal distribution, 9 sample plots were detected to be random distribution, 6 plots were homogenous distribution, but no plot was aggregated distribution. The mixed plantations displayed weak or middle level of mingling degree. Compared with C. lanceolata, the competiveness order of interplanted broadleaf trees wasC. fissa>S. superba > C. camphora > M. macclurei > M. maudiae. No significant deviation in spatial structure was detected among different deployments.
