摘　　要：专业学术词表对学术论文阅读与写作都有帮助。本文以环境科学为例创建专业学术词表，并对其有效性进行验证。首先建立环境科学英语语料库，选词时参照Coxhead（2000）编制“学术词表”（AWL）时使用的选词标准并根据实际情况进行适当调整，最终选取514个词族编制成环境科学学术词表（EAWL）。为了验证EAWL的有效性，本研究设计了测试语料库，利用Range词汇分析软件，进行AWL与EAWL在测试语料库中的覆盖率以及在单篇测试语料中的覆盖率的对比分析，结果表明，EAWL比AWL更适用于环境科学领域的学术词汇学习。Field-specific academic word lists contribute to academic article reading and essay writing. This research takes environmental science as an example to establish such a list and its validity is also verified. An Environmental Academic Word List（EAWL） , containing 514 word families, was compiled from an environmental science English corpus. Its word selection criteria refer to those of Coxhead＇ s Academic Word List （AWL） and appropriate adjustments are made in accordance with the practical situation of the environmental science English corpus. What＇ s more, three test corpnses are built and Range, a computer software for lexical analysis, is used to prove EAWL＇ s effectiveness. Coverage of AWL words and that of EAWL are compared in three test corpuses as well in 20 articles in one test corpus. The study reports that EAWL is more applicable to academic vocabulary learning in environmental science than AWL.
