摘要
对泉州湾不同潮汐高度的人工桐花树群落进行调查,结果表明,造林后8a,随着潮汐高度的下降,桐花树树高、胸径、冠幅、生物量显著下降,即高程1.7m,平均浸淹6-7h最适宜桐花树生长,不同潮汐高度的桐花树叶片中C、N、P含量差异不显著。野外调查还表明,高程0.5m的高潮位桐花树保存率低,生长缓慢,不适合桐花树生长。
The communities of Aegiceras cornieulatum in different tide height in Quanzhou Bay was investigated. The re- sults showed the height, DBH, crown breadth and biomass of 8-year-old A. eorniculatum decreased significantly with the tide height declined. The tide height of 1.Tm and flooding time of 6-7h in every tide cycle were optimal to the growth of A. eorniculatum. There was no great significant difference of C,N,P contents in leaves of A. eorniculatum in different tide heights. The field investigation also indicated A. corniculatum grew slowly with the 0.5m high tide position providing low survival rate, which was not suitable for the growth of this species.
