深圳市羊台山森林公园优良乡土阔叶树种选择技术研究

对广东省深圳市羊台山森林公园内的1块林分改造试验林和1块新造林的树种生长情况进行调查,分析不同树种生长的差异,以此为羊台山地区林分改造和新造林的树种选择提供理论依据。分析结果表明:林分改造试验林中选出14个树种,其林木生长较佳;新造林中紫荆、深山含笑、黄花风铃木、降香黄檀、阴香、土沉香和假苹婆7个树种表现优良。选出的21个树种按用途分为9种乡土生态阔叶树,8种景观树种,5种特色外来树种及4种珍贵树种。在羊台山进行森林公园林分改造或新造林时,树种选择应以乡土阔叶树为骨干,适当搭配景观树种,引进少量的珍贵树种和有特色的外来树种,这对于提升林分质量,改善森林景观,提升森林的文化内涵具有重要意义,同时为类似森林公园的林分改造和造林树种选择提供借鉴和参考。

Study on Selection of Native Broadleaf Tree Species in Yangtaishan Forest Park in Shenzhen

The growth of tree in two plots of test stands (a reconstruction and a new afforestation) in Yangtaishan forest park were investigated and analyzed. This paper is useful for selection of native broadleaf tree species in forest reconstruction in Yangtaishan forest park. In the reconstruction stand, 14 tree species grew well and were selected. In the new afforestation stand, 7 tree species grew well, including Bauhinia variegata, Michelia maudiae, Tabebuia chrysantha, Dalbergia odorifera, Cinnamomum burmannii, Aquilaria sinensis and Sterculia lanceolata. There are 9 species of native broadleaf trees, 8 species of landscape trees, 5 special exotic species and 4 precious species among the total 21 selected species. For tree selection in reconstruction and afforestation stand in forest park, native broadleaf species as the majority, collocation of landscape trees and a few precious species and exotic species should be the ideal mode. This mode is very important for improving stand quality, landscape and culture. This study is useful for improving ecological environment and landscape in Yangtaishan forest park, and could be referenced in tree selection in stand reconstruction and afforestation for similar forest parks.
