| Abstract | 对黄河三角洲滨海湿地不同水位条件下芦苇植被生态特征进行动态调查,并分析其与土壤理化性质的相关关系。结果表明:芦苇湿地土壤电导率随水位梯度变化差异显著,长期水淹的芦苇区土壤电导率最低;在不同水位梯度下,芦苇生态特征表现出较强的差异性,相比之下,在水位较高的条件下,芦苇株高、茎粗、盖度和生物量均为最高值,产量达到了10 t·hm~(-2);研究区土壤营养元素含量总体均处于较低水平,且不同水位条件下营养元素在各土层中的分布具有一定的差异;相关性分析表明,土壤粘粒、粗粘粒、细粉粒、粗粉粒与土壤营养元素均呈现不同程度的相关性,土壤有效磷含量与高度、茎粗、盖度、生物量均呈极显著正相关,因此土壤有效磷可能是黄河三角洲滨海湿地芦苇植被生长的限制性营养因子。 |
| Other Abstract | The ecological characteristics of Phragmites australis wetlands at different water table levels in the Yellow River Delta and the related, soil environmental factors were studied. The results showed that soil electrical conductivities (EC) of P. australis wetlands were significantly different at different water table levels. The lowest EC value occurred in the highest water table area. The ecological characteristics of P. australis wetlands showed great differences at different water table levels. The maximum values of plant height, shoot diameter, vegetation coverage and plant biomass occurred at the highest water table level. The plant biomass at the highest water table level was 10 t.hm(-2). The contents of soil nutrient elements in the study area were at relatively low levels, and also showed significant differences among the different soil layers. The correlation analysis showed that the soil nutrient elements had various correlation's with the contents of soil clay, coarse clay, fine silt, and coarse silt. The content of soil available phosphorus showed highly significant positive correlation with plant height, shoot diameter, vegetation cover age, and plant biomass. Therefore, it can be concluded that the soil available phosphorus is a limiting nutritional factor of plant growth in the coastal wetland of the Yellow River Delta. |
