中国语言多样性与生物多样性的建模分析
Modeling and Analysis of Language Diversity and Biodiversity in China

中国的汉语方言多样性和生物多样性具有区域相关关系。生物多样性和汉语方言多样性之间的关联性可能是由于一些公共因素的影响，本文验证了公共因素与中国各省的植被覆盖率和面积有关，建立结构方程模型综合地分析在去除公共因素影响后，由多指标构建的生物多样性和汉语方言多样性这两个潜变量之间的关系，并采用Lasso、MCP惩罚参数方法和Amos基于指定搜索方法进行模型选择。研究结果表明在去除面积、植被等公因子的影响后两者之间呈微弱的负相关关系。因此，我们要维护好自然环境，促进生物多样性与语言多样性的协同发展。
There is a regional correlation between the diversity of Chinese dialects and biodiversity in China. The correlation between biodiversity and Chinese dialect diversity may be due to the influence of some public factors. This paper verifies that public factors are related to the vegetation coverage and area of various provinces in China. A structural equation model is established to comprehen-sively analyze the relationship between the two latent variables, biodiversity and Chinese dialect diversity, constructed by multiple indicators after removing the influence of public factors. And us-ing Lasso, MCP penalty parameter method, and Amos based on specified search method for model selection. The research results show that there is a weak negative correlation between the two after removing the impact of common factors such as area and vegetation. Therefore, we need to main-tain the natural environment and promote the coordinated development of biodiversity and lin-guistic diversity.
