黄河口互花米草盐沼生物地貌演变过程研究
Biogeomorphology processes of Spartina alterniflora saltmarsh of the Yellow River estuarine
黄河口互花米草滩边缘有大量的贝壳沉积。在健康米草区、贝壳沉积区和光滩,随机选取3组进行挖槽(0.3mx0.3m)调查发现贝壳含量增加与互花米草的地上生物量和植株密度的减少有关。在此基础上,我们对黄河口互花米草盐沼生物地貌演变过程进行了分析。该研究成果表明贝壳滩的形成对黄河口盐沼湿地的破坏作用可能是海滨盐沼湿地退化的新机制。
he abundant of shells were accumulated on the surface of Spartina alterniflora edge. In the healthy Spartina alterniflora area, accumulate shell ridges area, and bare flats, Survey of marsh areas by dig pits(0.3mx0.3m)revealed that high-density of shells is relationship with over-ground biomass and density of planting. The results reveal shells acted to varying degrees to cause initial plant death. We analyzed the mechanism of evolution processes of Spartina alterniflora. These results suggest that damage to saltmarsh wetland by shell ridges is a novel mechanism for degradation wetland of salt marshes.
