摘要
采用固定样地定位调查的方法,研究深圳湾福田3种红树植物桐花树A egiceras corniculatum、秋茄Kandelia candel、白骨壤Avicennia marina伐后萌枝更新对伐迹地早期群落恢复的影响。结果表明:伐后4年时,3种红树植物平均萌生枝数由多到少的顺序为:桐花树(12.4)>白骨壤(5.4)>秋茄(4.4);桐花树的萌生率最大(72.73%),其次为秋茄(67.42%),白骨壤最小(20.77%)。滩涂潮位可能影响红树植物的萌生率,不同潮位滩涂上的红树植物萌生率为:内滩>中滩>外滩。红树植物萌生植株较人工种植植株的存活率高,且生长速度较快,表明萌枝更新对砍伐后早期红树林群落的恢复有重要意义。此外,红树植物种类自身的生理生态差异可能是影响萌生的重要因素之一。
The sprout regeneration of three dominant mangrove species were studied after 4 years of logging in Futian,Shenzhen bay,China.The results showed that the average sprouting number of three mangrove species were as follows:Aegiceras corniculatum(12.4)Avicennia marina(5.4)Kandelia candel(4.4).The sprouting rates were 72.73%,67.42% and 20.77% for A.corniculatum,K.candel,and A.marina,respectively.The sprouting ability of different intertidal zones were as follows:high tidal levelmiddle tidal levellow tidal level,that height of the tidal zone can affect the sprout regeneration of mangrove.The survival and growth rate of sprouting mangrove plant were higher than those of mangrove seeding plant,indicating that sprouting regeneration play a vital role in mangrove community recovery after clear cutting.Additionally,the physiological and ecological of mangrove plant itself may be one of the most important factors which affecting initiation.
