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。

Abstract: | 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
