摘要:

以互花米草入侵下的闽东滨海湿地为研究对象,通过对其土壤含水量、土壤孔隙度及土壤容重进行对比分析,运用IBM SPSS Statistics 19进行单因素方差分析(One-way ANOVA)检验数据差异显著性。结果显示:在溪南镇秋茄红树林单优势群落,互花米草单优势群落,50%秋茄红树林、50%互花米草混合群落,75%秋茄红树林、25%互花米草混合群落,25%秋茄红树林、75%互花米草混合群落这5个群落中,秋茄红树林单优势群落和互花米草单优势群落0~20cm土层深度与40~60cm土层深度的土壤含水量呈显著差异,但土壤孔隙度、土壤容重未呈显著差异;在50%秋茄、50%互花米草混合群落,40~60cm土层深度与0~20cm土层深度、20~40cm土层深度的土壤含水量、土壤孔隙度与土壤容重均呈显著差异;互花米草的入侵导致闽东滨海湿地土壤容重增加,土壤孔隙度减小,而土壤含水量变化趋势在不同秋茄-互花米草混合群落中呈现不同规律。

Abstract:

With eastern Fujian coastal wetlands under the invasion of Spartina alterniflora as the research object and through comparative analysis of soil moisture content,soil porosity and soil bulk density and using the IBM SPSS Statistics 19,the single factor variance analysis(One-way ANOVA)was performed to test the data difference significance.According to the results,the five communities in Xinan town include single dominant community of mangrove forest,single dominant community of Spartina alterniflora,50% autumn mangrove forest,50% Spartina alterniflora mixed community,75% autumn mangrove forest,25% Spartina alterniflora mixed community and 25% autumn mangrove forest,75% Spartina alterniflora mixed community.The soil moisture content of 0~20cm soil depth was significantly different from that in 40~60cm soil depth,but there was no significant difference in soil porosity and soil bulk density of the single dominant community of mangrove forest and single dominant community of Spartina alterniflora.The soil moisture content,soil porosity and soil bulk density were all significantly different in 40~60cm soil depth with 0~20cm soil depth and 20~40cm soil depth of 50% autumn mangrove forest,50% Spartina alterniflora mixed community.The invasion of Spartina alterniflora caused soil bulk density to increase,the soil porosity decrease and the trend of soil moisture content showed different patterns in different Kandelia Candel-Spartina alterniflora mixed communities in eastern Fujian coastal wetlands.

Key words: Spartina alterniflora, mangrove, soil moisture content, soil porosity, soil bulk density, eastern Fujian coastal wetlands
