Digitizing ethnic villages through VR technology is helpful for putting limited resources into the most urgent protection projects at this stage. In this paper, Basha village in western Hunan of China is selected as the carrier, and VR technology is used to simulate its virtual village scene. In this paper, ArcGIS is used to show the distribution of villages, through SketchUp software, 3D modeling of the buildings in the village is carried out, which is imported into Lumion platform and optimized, and finally the VR scene of Basha village is established. Through professional analysis tools, accurate reduction scale, and rational analysis and decision-making, it can not only open up a new situation for the protection of national history and culture, but also better promote the construction and renewal of new countryside.

Family farms are an important part of rural revitalization in China. Strengthening credit support for family farms is of great significance for increasing family farm income. This paper takes 1895 demonstrative family farms in Hunan Province as an example and proposes research hypotheses based on the theoretical analysis of the income growth effect of family farm credit. Based on the Cobb–Douglas theory, the Tobit model is used to make an empirical analysis of the income-increasing effect of family farms. And, we can add explanatory variables and QTE quantile effect model for testing. The results show that strengthening family farm credit support is conducive to increasing family farm income, and the coef. is 0.428. Family farm credit support is positively correlated with its total operating income. The more credit support for a family farm receives, the higher its total operating income. When the credit support of a family farm reaches a certain scale of 300,000 RMB, its income-increasing effect begins to diminish gradually. [ABSTRACT FROM AUTHOR]
