| 摘要: |
| 1992年于广西北海大冠抄测定了开阔海岸沙生白骨壤群落土壤的机械组成、有机碳和腐殖质的含量,及红树群落的结构和生物量等。由向陆林带到向海林带,土壤的粉粒粘粒含量和有机质含量随着群落树高和生物量的下降而降低,植物在相当程度上决定了土壤的特征。木榄、红海榄只偶见于向陆林带,桐花树和秋茄可生长到中间林带。这种分带现象部分地取决于土壤的质地和有机质含量。在土壤的垂直剖面上,植物跟土壤间也存在与上述相似的关系。这些表明,先锋红树植物白骨壤与土壤的共同进化为后来种创造了适宜的生境。在此基础上,提出了广西沙生红树林演替的模式。 |

| Abstract: |
| The soil mechanical composition,contents of organic carbon(OGC),humic matter (HUM) and mangrove community structure,biomass were measured in 1992 at an open coastal sandy Avicennia marina dominated forest in Daguansha,Beihai,Guangxi.The contents of soil silt,clay,GOC and HUM decrease with the decreasing mangrove tree height, aboveground and underground biomass,indicating that the soil properties are depended on plants to a great extent.Bruguiera gymnorrhiza and Rhizophora stylosa only occasionally occur at landward forest zone,but Aegiceras cornicultum and Kandelia candel can reach the middle zone.The zonation are partially governed by soil texture and organic matter.A similar relationship between plant and soil is also observed in vertical soil profiles.These suggest that the coevolution of pioneer A.marina and soil creates an adapted habitat for the posterior species.On this basis,a succession pattern of sandy mangrove community in Guangxi is developed. |
