| 摘 要： | 为阐明湿地土壤理化特征对潮汐的响应,对闽江河口外来入侵种互花米草斑块湿地和土著种短叶茳芏湿地土壤理化特征进行了测定和分析。结果表明:①互花米草斑块湿地和短叶茳芏湿地涨潮前和落潮后土壤理化特征差异不显著(p>0.05);②互花米草斑块湿地落潮后的土壤盐度、pH值和Eh与涨潮前的土壤以上指标的相关性高于与潮水以上指标的相关性(p<0.01),短叶茳芏湿地土壤Eh也表现出同样的规律,但盐度、pH值则与潮水相应指标的相关性更高(p<0.01);③互花米草斑块湿地和短叶茳芏湿地土壤盐度、pH值和Eh潮汐敏感性存在着不同的季节变化模式,在潮水盐度、pH值和Eh分别为0～3ms/cm、7.0～7.5和负值的情况下对潮汐的响应较为敏感。

| Abstract: | To understand the effects of plant invasion on soil properties and the responses of soil properties to tide,soil properties of the wetland with invasive alien plant(Spartina alterniflora) and the wetland with native plant(Cyperus malaccensis) were analyzed.The results showed:soil pH was increased and Eh was declined after Spartina alterniflora invasion,but not statistically significant(P>0.05).The soil properties did not significantly differ between before and after the tides(P>0.05).The correlation of sali... |
