摘要
通过研究热带风暴对海南岛东寨港海桑(Sonneratia caseolaris)-无瓣海桑(Sonneratia apetala)人工红树林及角果木(Ceriops ta-gal)-红海榄(Rhizophora stylosa)天然红树林群落结构的影响表明,热带风暴后海桑-无瓣海桑人工林树高、东西冠幅、南北冠幅平均值分别减少2.8%、14.3%、12.1%,枝下高增加60.0%;角果木-红海榄天然林的树高增加8.3%,东西冠幅、南北冠幅无变化,枝下高增加20.0%;热带风暴对人工林的影响比天然林大;热带风暴前后不同树种的树高增长顺序为角果木>红海榄>无瓣海桑>海桑;对冠幅的影响程度依次为角果木<红海榄<海桑<无瓣海桑;对枝下高的影响程度依次为角果木<红海榄<海桑<无瓣海桑;在热带风暴的影响下,海桑-无瓣海桑人工林凋落的生物量损失平均为0.22t/hm2,干生物量损失平均为0.13t/hm2;角果木-红海榄天然林生物量损失极小。总体而言,人工林中海桑的抗风性优于无瓣海桑,天然林中角果木的抗风性优于红海榄,天然林的抗风性优于人工林。
The effects of tropical storm on the forest structure of Sonneratia caseolaris-Sonneratia apetala plantation mangroves and Ceriops tagal-Rhizophora stylosa natural mangroves were analyzed,and the results showed that after the storm,the average height,CW（E-W）and CW（N-S）of S.caseolaris-S.apetala plantation mangroves were decreased by 2.8%,14.3% and 12.1% respectively,but the mean of clear bole height was increased by 60.0%.For C.tagal-R.stylosa natural mangroves,the average height was increased by 8.3%,but CW（E-W）and CW（N-S）almost not change,and the clear bole height was increased by 20.0%.Therefore,the effect of the tropical storm on the plantation mangroves was greater than natural forest.The tropical storm influence on tree height of different species was in the order that C.tagal R.stylosa S.apetala S.caseolaris.The influence on CW was in the order that C.tagal R.stylosa S.caseolaris S.apetala.The influence on the clear bole height was in the order that C.tagal R.stylosa S.caseolaris S.apetala;Under the effect of the tropical storm FRANCISCO,the biomass loss of plantation mangroves was 0.22 t/hm2,and the dry biomass loss was 0.13 t/hm2,while the effect of the tropical storm on the biomass of C.tagal-R.stylosa natural mangroves was infinitesimal.Totally,the wind resistant ability of natural mangroves was better than plantation mangroves,and C.tagal was better than R.stylosa,and S.caseolaris was better than S.apetala.
