| 摘 要： | 研究了福建九龙江口秋茄(Kandelia candel)红树林潮间带的红藻鹧鸪菜(Caloglossa leprieurii)的氮、磷、钾、钠、钙与镁6种营养元素含量的季节变化。氮、磷、钾与钠均以春季含量最高；钙与镁分别以秋季和冬季最高。氮与磷含量冬季最低，钾含量秋季最低；钠、钙、镁均以夏季含量最低，6种元素含量的季节变化模式不一致。营养元素含量的季节变化表明鹧鸪菜春季富集的营养物质较多，与春季有较高的生物量一致。营养元素含量的季节变化反映了鹧鸪菜的生长与环境因子的季节变化。鸥鸪菜的氮、磷含量高于土壤含量。并明显高于水体氮、磷含量，说明鹧鸪菜能强烈富集环境中的氮、磷，因此鸥鸪菜类的大型藻类的存在可能是红树林区赤潮极少发生的原因之一。

| Abstract: | Seasonal variations ofsixnutrientelements ofred alga Caloglossa leprieurii were investigated in Kandelia candel forestin JiulongjiangEstuary,Fujian of China.The concentrations of nitrogen,phosphorus,potassiumand sodiumwere the highestin spring.However,those of calcium and magnesiumwas the highest in autumn and winter respectively.The concentrations of nitrogen and phosphorus were the lowest in winter and that of potassiumwas the lowest in autumn respectively.But the least concentration ofsodium,calciumand magnesiumwere in summer.Seasonal patterns of concentrations of sixnutrientelements were different one another.Seasonal variations of concentrations of six nutrient elements indicated that the red alga C.lep-rieurii enriched abundantnutrient matters in spring,whichwere identical with accumulating higher biomass in this season.At the same time,Seasonal variations ofnutrientelements reflected seasonal changes ofgrowthofthe red alga C.leprieurii and its environmental factors.The concentrations of nitrogen and phosphorus were higher in samples of red alga C.leprieurii than in ones of soil and were much more higher than in ones of water,which manifested that the red alga C.leprieurii could greatly enrich nitrogen and phosphorus fromenvironments.Therefore,it was preliminarily speculated fromthis investigation that the macroalgae such as C.leprieurii was one of the reasons why no red tide occurred in mangrove areas. |
