| 摘要: |
| 本文研究了广西北海大冠沙白骨壤树上大型固着动物的种类组成、数量分布特点及其对植物体的危害。结果表明,大冠沙白骨壤群落中的大型固着生物有10种,分属3门4纲6科,其中在白骨壤植株上的主要种类为白条小藤壶、潮间藤壶、褶牡蛎和黑荞麦蛤4种。危謇程度最大的是白条小藤壶,其湿重生物量占总湿重生物量的百分比高达72.3%~100%。受害程度最大的是向海林带的枝和叶,其动物生物量干重与植物生物量干重的比值(a/p)可达30.49×10-2和30.43×10-2。就整个红树林区而言,危害程度为向海林带(21.68×10-2) > 中间林带(7.88×10-2) > 向陆林带(0.01×10-2).同一林带的植株受害程度为较低树层的大于较高树层的.密度和生物量的分布也与此相类似. |

| Abstract: |
| This paper deals with species component,numerical distribution and its damage to plants of the macrofauna attaching to Avicennia marina trees in Daguansha,Beihai,Guangxi.It is revealed that there are 10 species,belonging to 6 genera in 4 families and 3 orders,of macrofauna attaching to A.marina community,of which Chthamalus withersi,Blanus littorlis, Ostrea plicatula and Vignaduld atrata are the major.The species that does the greatest damage to plants is Chthamalus withersi,its fresh biomass making up of 72.3% to 100% of the total fauna fresh biomass.The branch and leaf are harmed in higher degree,of which the ratioes of macrofauna dry biomass to plant dry biomass are 30.49×10-2 and 30.43×10-2.As a mangrove zone,the damage decrease from seaward(21.68×10-2) to middle(7.88×10-2) and to landward(0.01×10-2).In the same forest zone,the damage decrease from lower tree layer to higher tree layer,so do the distribution of density and biomass. |
