以秋茄、桐花树、白骨壤和木榄等4种红树为研究对象，测定了这4种红树在自然生境中的光合作用对光和CO2的响应曲线，阐述了其光合作用对光和CO2浓度的响应特征。结果表明，不同红树光补偿点（LCP）和光饱和点（LSP）不同，4种红树 LCP为白骨壤（81．95μmol · m -2· s-1）＞桐花树（61．84μmol · m -2· s-1）＞秋茄（47．09μmol·m -2·s-1）＞木榄（39．79μmol·m -2·s-1），LSP为桐花树＞秋茄＞白骨壤＞木榄；不同红树间表观量子效率存在差异，秋茄的表观量子效率最高为0．031，木榄最低为0．012，桐花树（0．027）高于白骨壤（0．017）；4种红树植物光合作用的CO2补偿点介于103～152μmolCO2· mol-1，说明4种红树均为C3植物；CO2补偿点从大到小的顺序为木榄＞白骨壤＞桐花树＞秋茄；4种红树羧化效率（CE），最大的为桐花树，其次为秋茄，再次为白骨壤，木榄最低。

Taking four mangrove species (Kandeliacandel ,Aegiceras corniculatum ,Avicennia marina ,& Brugui-era gymnorrhiza) as research objects ,the response curve of net photosynthetic rate in above-mentioned mangroves on light intensity & CO2 concentration in the natural habitat was measured .Response characteristics of their light intensity & CO2 concentration on photosynthesis were described .Result shows that :the light compensation point (LCP)& light saturation point (LSP) of the four mangrove species are different .The LCP of the four mangrove species was that Avicenniamarina(81 .95μmol· m -2 · s-1)> Aegicerascorniculatum(61 .84μmol· m -2 · s-1)>Kandeliacandel(47.09 μmol·m -2·s-1)> Bruguieragymnorrhiza(39.79 μmol·m -2·s-1);theLSPisthat :Aegicerascorniculatum > Kandeliacandel > Avicenniamarina > Bruguieragymnorrhiza;theapparentphoto-synthetic quantum yield (AQY) point of the four mangrove species have differences ;the AQY (CO2 · photon-1 ) from high to low is :Kandeliacandel (0 .031) > Aegiceras corniculatum(0 .027)> Avicennia marina (0 .017)>Bruguiera gymnorrhiza (0 .012);the CO2 compensation point (CCP) of the four mangrove species range from 103-152 μmolCO2 · mol-1 ;it illustrates that the four mangrove species are all light-demanding C3 plant ;the descending orderofCCPis Bruguieragymnorrhiza > Avicenniamarina > Aegicerascorniculatum > Kandeliacandel ;the descending order of carboxylation efficiency (CE) of the four mangrove species is Aegiceras corniculatum > Kan-deliacandel > Avicennia marina > Bruguiera gymnorrhiza .
