Ecological Niche Of Dialedt In Eco-Civilization Construction

Since the18th People Congress, a grand blueprint for eco-civilization construction has been laid out. Eco-civilization construction is system engineering. It is closely related to every aspect of nature, society and human. As the most important communication tool of people, language is a kind of natural and social phenomenon. Therefore, linguistic ecology is a point of strong support for eco-civilization construction. Although the ecology of language of our country is rich and colorful, there are some hidden factors of disharmony. For dialects, their decline, their conflict with mandarin and their division have attracted increasing public attention with the rapid development of urbanization. While dialects are stepping towards predicament, people’s attitude towards them are still inconsistent. So the ecology of dialects is still worsening. At present, the strategy of new urbanization has been proposed. It pays more attention to harmonious development. The harmony of language is the manifestation as well as a cornerstone of social harmony. If the problems of dialect couldn’t be solved for a long time, they would probably threaten the construction of linguistic harmonious ecology, even influence the overall situation of eco-civilization construction.The reason dialect becomes a problem is that people’s perspective of dialect study is still conventional. The rise of ecolinguistics provides us a new viewing angle, and that is ecological outlook. All the languages including dialects are not self-sufficient systems. They all need to have space, resources and functions, while ecological niche of a language or dialect is the sum of its existence condition and value. This paper combines ecological niche theory, which is a research hotspot of ecology with dialect study to present the concept of dialect ecological niche, and then take Hangzhou dialect for example to discuss relevant issues of its ecological niche from the perspective of eco-civilization construction.This paper falls into six parts. Introduction presents background, significance, mentality and framework. Chapter one to five is the main part. Chapter one expounds the applicability of ecological niche theory of species in language study, and then proposes the concept of three-dimensional language ecological niche. Chapter two talks about dialect diachronic from the perspective of adapting to ecological niche and discusses how a dialect can get new features under the influence of its ecological niche. Chapter three talks about language competition from the perspective of niche overlap and discusses about how a dialect can reduce overlaps by optimizing its ecological niche to achieve collaborative development rather than elimination. Chapter four presents case study on news program in dialect and mandarin to explore the relationship between dialect and mandarin, and then discusses how to make their niches reach a complementary state so as to promote language harmony. Based on the discussion above, the last chapter expounds how to keep the ecological niche of a dialect to achieve its sustainable development.
