Geolinguistics is based on linguistic fact-finding，Use bet365 champions league maps to describe the geographical distribution of bet365 champions league phenomena，Combining sociocultural factors to explain the reasons for these distributions，Exploring the process and mechanism of bet365 champions league change。Using geolinguistic theories and methods to study Chinese dialects in China，The earliest Chinese dialect characteristic map is the "Guangdong and Guangxi" dialect map。Research on geolinguistics of Chinese dialects，The study of ethnolinguistic geolinguistics started late。With the development of bet365 champions league resource protection project，The protection of endangered languages ​​​​has received attention and attention from the academic community。Digitalization is an important means to help protect endangered languages。Use the theories and methods of geolinguistics to study the synchronic distribution and diachronic evolution of endangered languages，It is also an important way to protect endangered languages。

　　Expand bet365 champions league ideas on endangered languages

China’s ethnic minority languages ​​are rich and complex。With the continuous development of history，Ethnic minority languages ​​are influenced by other ethnic cultures to varying degrees、bet365 champions league、Customs and environmental impact，The situation of bet365 champions league blending is complicated。Therefore，Should be based on multiple angles、Use multiple methods，Deepening research on minority linguistics。Take Oroqen bet365 champions league as an example，A wealth of research results have been achieved so far，Diverse research angles，Rich theoretical methods，Includes linguistic typology、Experimental Linguistics、Historical Comparative Linguistics、Comparative linguistics, etc.。But，As of now，No scholar has studied Oroqen bet365 champions league from a geolinguistics perspective。

The Oroqen people are one of the smallest ethnic minorities in Northeast China。The Oroqen people have their own bet365 champions league，But no text。The Oroqen people used to live in deep mountains and dense forests，In semi-closed state，Is one of the ethnic minorities who settled downhill later in China，After settling down the mountain, the residential areas are relatively concentrated，So the Oroqen bet365 champions league has been handed down relatively completely。Oroqen bet365 champions league has dialect differences，The dialect differences are formed based on the distribution area of ​​the Oroqen people。From the geographical distribution area of ​​the Oroqen people，Each region is not only relatively concentrated，In addition, each tribe is subject to clear management areas set up by the government administration.。If things continue like this，formed its own dialect area。Although there are differences in each dialect area，But they can communicate with each other。Oroqen is an endangered bet365 champions league，Geolinguistics can provide new ideas for its research。

Currently，The study of Oroqen bet365 champions league mainly involves grammar、Vocabulary、Voice characteristics, causes of endangerment and conservation strategies, etc.。First，Research results in grammar，Mainly grammatical structure、Typological perspective analysis of sentence structure features and focus on the usage of a certain type of words。Secondly，Research on speech，The results are mainly the use of experimental phonetics research methods，Analysis of the acoustic characteristics of Oroqen bet365 champions league and phonetic differences between neighboring ethnic groups。Finally，Because Oroqen is an endangered bet365 champions league，The academic community has also produced research on the causes of its endangerment and protection methods。

Most of the above research results are synchronic studies of Oroqen languages，There are also scholars who interpret this from the perspective of diachronic comparative linguistics。Currently，There are few results published on Oroqen bet365 champions league research from the perspective of geolinguistics，Weak research on geographical distribution and differences between different dialects of Oroqen bet365 champions league。Geolinguistics can provide basic materials for relevant arguments。Cao Zhiyun pointed out，“Because a bet365 champions league develops and evolves at different speeds in different places，Differences between local languages ​​on the synchronic plane，In fact, it may be the remains of the characteristics of different historical stages of the bet365 champions league，In other words，Synchronic differences in bet365 champions league can reflect diachronic changes in bet365 champions league”。Therefore，In the historical comparative study of Oroqen bet365 champions league，Geolinguistics can be applied。

Geolinguistics can enrich the theory of historical comparative linguistics。Observations and explanations of a bet365 champions league，Need to place it in a wider geographical space。bet365 champions league changes are not only due to internal reasons within the own system，There are also the effects of external factors，Like custom、Administrative Region、Geographical environment、Topography, etc.。These factors can be presented through geolinguistics。

In addition，“Wave theory” can also be used as a theory and method to improve historical comparative linguistics。According to "Wave Theory"，The diffusion of bet365 champions league moves forward in both directions from the center to the surroundings。In the process of diffusion，The influence of bet365 champions league will be somewhat resisted，When resistance is invalid，Another bet365 champions league will merge、Change to final acceptance，There will also be reverse effects。Within a geographical area，Focus on stronger languages，Spread around，And influence further languages ​​through surrounding languages。The "Wave Theory" can supplement the deficiencies in bet365 champions league differentiation research in terms of time，The research results have certain reference value for historical comparative linguistics。Therefore，Based on geolinguistics，From the perspective of historical comparative linguistics and "wave theory"，Can expand the research ideas of Oroqen bet365 champions league。

　bet365 champions league and protection promote each other

Current，In order to protect endangered languages, our country has formulated corresponding policies for the protection of bet365 champions league resources，And established multiple research institutions。Oroqen as an endangered bet365 champions league，It is also the target bet365 champions league of the bet365 champions league protection project，Currently, personnel from relevant institutions have collected corpus materials in Inner Mongolia Autonomous Region and Heilongjiang Province。current，Protection of bet365 champions league resources，Mainly focused on three levels - preservation、Inheritance and dissemination。

With the development and application of digital technology，It is now possible to save entity languages。Therefore，Proposed by relevant experts，Details can be drawn through the bet365 champions league multimedia database、Accurate multimedia bet365 champions league map。Before drawing multimedia bet365 champions league map，bet365 champions league maps that can use geolinguistics，Multimedia map interpretation of Oroqen bet365 champions league。The advantage of bet365 champions league map is，It can reflect the phonetic characteristics of the Oroqen bet365 champions league under investigation、Differences in vocabulary and grammar。In addition，The survey pattern of geolinguistics is distributed in a network，Can grasp the bet365 champions league characteristics of Oroqen more intuitively、Regional distribution and trend。At the same time，Because the survey content of geolinguistics needs to be unified，It also makes the survey results more convincing。Explanation of bet365 champions league map，Should be based on the internal evolution of bet365 champions league and external non-linguistic factors。

Generally speaking，Geolinguistics can integrate Oroqen bet365 champions league materials，Explained at the geographical and social levels。bet365 champions league map drawn based on geolinguistic theory，Can present the face of Oroqen bet365 champions league in a more complete and systematic manner，Provide basic materials for multimedia mapping, historical comparative linguistics and ethnic minority regional culture research，Promotes the protection of Oroqen bet365 champions league。

There are many ethnic minorities in our country，Languages ​​are many and varied。With the continuous development of science and technology and the deepening of economic globalization，The diversity of national traditional culture is in crisis。Theories and methods of geolinguistics，Can provide a new research perspective for the study of endangered languages。The geolinguistic research on Chinese dialects has a history of more than 70 years，Achieved rich research results。Based on the current relevant results，Geo-linguistic research on minority languages ​​mainly focuses on minority languages ​​in the south，There are few relevant studies on minority languages ​​in Northeast China。Currently，The Manchu Tungus bet365 champions league is in an endangered state due to changes in the living environment and production methods，Especially Manchu and Hezhe，The endangered situation is more serious。Zhao Aping proposed in "Construction and Research of the Chinese Manchu-Tungus bet365 champions league Corpus Database"，At present, it is very necessary to rescue the Manchu and Tungus bet365 champions league and culture, establish a corpus database, and carry out comprehensive and systematic research。The method of constructing the Manchu Tungusic corpus database mentioned in this article，Mainly including structural linguistics、Human Linguistics、Multidisciplinary theoretical methods such as sociolinguistics and computational linguistics。

The core ideas of geolinguistics，is the geographical distribution through bet365 champions league features，Deduced the trajectory of voice evolution。Therefore，While conducting fieldwork，Can connect languages ​​in adjacent areas，Obtain the evolution trajectory of a specific speech project。Complex linguistic and geographical differences as well as a long national history and rich social and cultural background，Is very fertile soil for geolinguistic research。Therefore，Carry out geolinguistic research on Oroqen and other endangered languages，Can promote the maturity and progress of geolinguistics research methods，Enrich the types of research on minority languages ​​in my country，And provide support for the protection of endangered languages。
