摘　　要：以深圳福田红树林保护区为研究对象,选取红树林试验地,于2014年5月对试验地引入的红树物种——海桑和无瓣海桑进行人工间伐调控;2014年6月至2015年5月,每月对间伐后红树植物的自然恢复状况进行调查。结果表明,试验地内共有红树4科4属5种,分别为秋茄、桐花树、海桑、白骨壤和无瓣海桑,重要值分别为36.72、32.51、20.96、5.28和4.53,调控后试验地乡土红树在自然恢复过程中发挥重要作用,海桑比乡土红树有较快的生长速度,会逐渐与乡土物种形成较强的竞争,为保证试验地乡土红树的竞争力,需对海桑进行多次人工调控;试验地内的物种丰富度较高,但各树种个体数量分布不均匀,建议进行乡土红树的人工补植,增加各树种在试验地内的数量,提高红树群落结构的稳定性。A structural regulation experiment was carried out to decrease the abundance of the introduced mangrove species Sonneratia caseolaris and S. apetala in a mangrove forest in Futian Mangrove Reserve in Shenzhen Bay in May 2014. The natural restoration of mangrove plants was investigated once a month during June 2014 to May 2015. The results showed that there were five mangrove species in the testing plots,including Kandelia obovata,Aegiceras corniculatum,S. caseolaris,Avicennia marina and S. apetala. Their importance values were 36. 72,32. 51,20. 96,5.28 and 4.53,respectively. After thinning,native mangrove plants played a more important role in the natural recovery process,whereas introduced mangrove S. caseolaris grew faster,competing with the native mangrove species. In order to improve the competitive ability of native mangrove species,multiple artificial regulations for S. caseolaris are needed in the future. The species richness within the testing plots was high,but the individuals of each species distributed unevenly.Therefore,supplementary planting of native mangrove species is needed in the future to ensure the stability of mangrove community structure.
