环境话语生态性构建研究:以“《中国日报》气候变化报道话语语料库”为例

环境话语是与环境或环境问题相关的一类话语，受到学界关注。生态话语分析作为生态语言学的一个研究视角，在话语生态性构建方面的作用日益凸显。语料库话语分析或研究作为一种实证性视角被广泛用于语篇或话语研究中。语料库生态话语分析将上述两个视角整合，是话语生态性探索的新路径。研究立足于气候变化的大背景，基于一定的生态哲学观（融合“人类命运共同体”的生态向度和“人与自然是生命共同体”这一生态自然观），借助专用语料库工具，建立“《中国日报》气候变化报道话语语料库”（包含一个总库与四个子库），从子库词表、子库主题词表和总库中索引项climate change及其搭配这三个方面展开论证。研究发现，作为环境话语的《中国日报》气候变化报道是生态有益型话语，报道表达并构建人与自然和谐发展的关系，阐明该报对气候变化这一环境相关问题的态度，同时凸显其中国立场与全球视野。 

The Construction of Ecological Features of Environmental Discourse:As Exemplified in the"China Daily News Corpus of Climate Change"

As a type of discourse related to natural environment or environmental problems, environmental discourse has been widely studied in academia. Ecological discourse analysis, a research perspective of ecolinguistics, has been gaining importance in the construction of ecological features of ecologically related discourse or discourse of any theme or type. Corpus-assisted or corpus-aided discourse analysis, a positivistic perspective, is a general practice in discourse analysis. Through the combination of the two perspectives, a corpus-assisted/aided ecological discourse analysis, serves as a new approach to the construction of ecological features of discourse. Against the backdrop of climate change across the world, the ecological discourse analysis is enacted closely in line with the ecosophy which integrates the ecological dimension of a “community with shared future for mankind” on the one hand, and “man and nature are in the same biotic community” as an ecological view of nature on the other hand. With the help of specialized corpus tools, this study compiles a “China Daily News Corpus of Climate Change” (with 1 main corpus with 4 subcorpora), analyzing the data in terms of the wordlists of the subcorpora, the keyword lists of the 4 subcopora, and the concordance of the key word in context (i.e. “climate change”) and its collocations in the whole corpus. As a type of environmental discourse, China Daily's news of climate change turns out to be ecologically beneficial due to its conveyance and construction of a harmonious relationship between man and nature; explication of the newspaper's attitude toward issues involving climate change; and emphasis on the Chinese position as well as the global vision.
