植物在修复多环芳烃（PolycyclicAromaticHydrocarbons，PAHs）等有机物污染的土壤中有较大的应用潜力。植物修复污染土壤的纵深研究产生了根际修复新技术。根际环境与根际微生物是植物降解、转化有毒有害有机污染物的基础。本论文在评价红树植物秋茄（Kandeliaobovata）修复菲（Phenanthrene，PHE）污染沉积物的潜能基础上，探讨了根际和非根际沉积物微生物和酶活性对不同浓度（5、10、20、40mg•kg-1）菲的响应。同时采用多隔层三室根箱法将根际划分为根室、2mm、4mm、6mm三个近根际、以及>6mm远根际，研究菲在各毫米级根际微域的消减动...Polycyclic aromatic hydrocarbons (PAHs) are ubiquitous environmental pollutants that possess carcinogenic and mutagenic properties. Due to their high toxicity and wide distribution in the environment, PAHs have been listed as priority pollutants by the United States Environmental Protection Agency (USEPA). Mangrove ecosystems, important inter–tidal estuarine wetlands along the coastlines of tropi...学位：理学博士院系专业：生命科学学院生物学系_生态学学号：2162007015379
