10个热带滨海城市防台风防护林树种的早期生长分析

Early growth properties of 10 tree species of tropical coastal city anti-typhoon shelter plantation

通过对海南三亚城市防台风试验示范林的10个参试热带树种从地径、树高和冠幅三个生长指标进行跟踪监测,分析各个树种的生长状况,综合比较其生长速度后,列出这10个树种的生长排序,并对各树种的早期生长特性及适宜种植模式进行了初步评价,结果表明:格木、非洲楝、孔雀豆等生长速度较快的树种可以作为城市防台风林群落构建的中上层乔木或者早期先锋树种,而生长慢的长叶马府油、小叶杜英等则可以作为中下层和后期演替树种或防风林带前沿树种,研究结果可为三亚市防台风防护林建设和城市景观森林群落构建提供科学依据。

10 tropical tree species were selected and planted as an experiment plantation of anti-typhoon shelter in Sanya, Hainan, China. Through monitoring the basal diameter, tree height and crown width for two years after planting, the early growth properties were analyzed. According to the results of comprehensive comparison and ordination of their growth rates, the fast growing species such as Erythrophloeum fordii, Khaya senegalensis, Aclenanthera paeonina can be used as upper-layer trees or pioneer species of the anti-typhoon shelter forest community; Madhuca longifolia and Elaeocarpus hainanensis which grow slower can be used as frontier trees of anti-typhoon shelter forest or late succession species. The results can provide scientific basis for planting typhoon shelter forest and urban forest in tropical coastal cities in southern China.
