| 摘要: |
| 基于2008年广东省天井山林场冰灾受损杉木林6种人工套种模式以及自然恢复模式的18个面积为400 m2样地的调查数据，对该区域受损杉木林的植物群落结构及其生物多样性进行了初步研究。结果表明，群落类型有杉木+红花荷、杉木+峨眉含笑、杉木+火力楠、杉木+枫香、杉木+南酸枣、杉木+观光木+深山含笑、杉木纯林。群落的乔木层常见树种为杉木、红花荷、峨眉含笑、火力楠、枫香、南酸枣、阿丁枫、观光木及深山含笑等；灌草层植物以蔓生莠竹、唐竹、山苍子 、淡竹叶、空心泡等植物为优势种。各群落乔木层Shannon Wiener指数从大到小依次为：杉木+观光木+深山含笑＞杉木+红花荷＞杉木纯林＞杉木+枫香＞杉木+南酸枣＞杉木+火力楠＞杉木+峨眉含笑；灌草层Shannon Wiener指数由大到小依次为：杉木+红花荷＞杉木+观光木+深山含笑＞杉木+枫香＞杉木+火力楠＞杉木+峨眉含笑＞杉木+南酸枣＞杉木纯林。 |

| Abstract: |
| Structure and biodiversity of six artificial interplant types and the natural recovery mode of Cunninghamia lanceolata plantation which were damaged by ice disaster in 2008 in Northern Guangdong were investigated and studied by plot survey. The results showed that there were seven types of forest communities, including Cunninghamia lanceolata Rhodoleia championii, C. lanceolata Michelia wilsonii, C. lanceolata Michelia macclurei , C. lanceolata Liquidambar formosana, C. lanceolata Choerospondias axillaris , C. lanceolata Tsoongiodendron odorum Michelia maudiae communities, and C. lanceolata forest，were studied. The dominant species in tree layer were C. lanceolata, Rhodoleia championii, Michelia wilsonii, M. macclure, Liquidambar formosana, Choerospondias axillaris, Altingia chinensis, Tsoongiodendron odorum, and Michelia maudiae. The shrub and herb layer dominant species mainly included Microstegium vagans, Sinobambusa tootsik, Litsea cubeba, Lophatherum gracile, and Rubus rosifolius. The Shannon Wiener indexes of tree layer in seven communities were different, and they were ranked in a descending order as follows: C. lanceolata Tsoongiodendron odorum Michelia maudiae＞C. lanceolata Rhodoleia championii ＞ C. lanceolata forest ＞ C. lanceolata Liquidambar formosana ＞ C. lanceolata Choerospondias axillaris ＞ C. lanceolata Michelia macclurei ＞C. lanceolata Michelia wilsonii. The Shannon Wiener indexes of shrub layer were ranked as follows: C. lanceolata Rhodoleia championii ＞C. lanceolata Tsoongiodendron odorum Michelia maudiae ＞C. lanceolata Liquidambar formosana ＞C. lanceolata Michelia macclurei ＞ C. lanceolata Michelia wilsonii＞ C. lanceolata Choerospondias axillaris ＞C. lanceolata forest. |
