摘要： 互花米草是全球海岸滩涂湿地生态系统最成功的入侵植物之一，对中国沿海湿地土壤生态系统也产生了重大影响。本文主要从入侵地土壤生态系统的结构组分(土壤微生物和土壤动物)与物质循环(土壤碳循环、氮循环、磷循环和重金属元素)两大方面，综述了近年来国内外互花米草入侵对沿海滩涂与河口地区土壤生态系统的影响。此外，本文还指出了未来互花米草的研究方向，包括加强互花米草对入侵地土壤微生物的影响的研究，整合互花米草对地上、地下资源竞争和生态过程影响的研究，以及互花米草在全球变化大背景下入侵动态预测。

Abstract: Spartina alterniflora is one of the most successful invasive weeds in global estuaries and coastal wetland areas, and also,has major impacts on the coastal wetland soil ecosystems in China. This paper summarized the recent researches about the influence of S. alterniflora invasion on the soil ecosystems in estuaries and coastal wetland areas, mainly from the aspects of soil structural constituents (soil microbes and soil animals) and matter (carbon, nitrogen, phosphorus, and heavy metals) cycles. The shortcomings of the ongoing researches were discussed, and the future research emphases, e.g., the influence of the invasion on soil microbes, the integration of the studies of above- and below-ground resources competition between S. alterniflora and native plants and related ecological processes, as well as the simulation and prediction about the invasion dynamics of S. alterniflora under the background of global climate change, were suggested.
