摘要/Abstract

摘要： 为阐明外来物种入侵对生态系统的改变,对闽江河口区本土植物短叶茳芏和不同入侵年限的互花米草湿地土壤总碳(TC)、总氮(TN)、总磷(TP)含量进行了测定与分析.结果表明: 互花米草入侵后0～50 cm深度各层土壤TC、TN和TP含量均有不同程度的增加,其中TC、TN的变化比较一致,而TP的变化滞后;TC的增加引起土壤C/N持续增加,而TP是调节互花米草入侵过程中湿地土壤C/P和N/P的关键因子,C/P和N/P的变化基本一致.土壤TC、TN、TP的变化受到土壤盐度、容重、含水量和黏粒组成的影响,而它们之间计量比主要受土壤盐度、粒径组成的影响;C/N和C/P对互花米草湿地的土壤固碳效应具有良好的指示作用.互花米草入侵引起生物量和湿地生境改变,导致土壤碳氮磷含量及其生态化学计量比发生显著变化,且随入侵时间延长表现出不同的变化特征.

Abstract: To clarify the effect of invasive alien plants on ecosystem functions, soil total carbon (TC), total carbon (TN), and total phosphorus (TP) contents were studied in the exotic invasive plant Spartina alterniflora marsh with different durations and the native species Cyperus malaccensis marsh in the Minjiang River estuary. The results showed that there were different variations of TC, TN and TP at 0-50 cm soil layer in the C. malaccensis marsh invaded by S. alterniflora, but the changes of TC and TN were similar and the change of the TP lagged behind them. Soil C/N increased continually with the increase of TC. Soil TP was a key factor affecting soil C/P and N/P during the S. alterniflora invasion, and the change of C/P and N/P followed a similar trend. The changes of TC, TN and TP were influenced by abiotic factors such as soil salinity, bulk density, soil water content and clay composition. C, N and P stoichiometric ratios were influenced mainly by soil salinity and grain composition. C/N and C/P were the good indicators for soil carbon enrichment ability in S. alterniflora marsh. S. alterniflora invasion induced the change of biomass and marsh habitats. Soil carbon, nitrogen, phosphorus contents, and their ecological stoichiometric ratios changed significantly in the C. malaccensis marsh invaded by S. alterniflora and showed diffe-rent change characteristics with different invasion duration.
