Furthermore, the re- gional characters of Nanzheng County were investigated to analyze the feasibility and necessity of relocation with lots of data and evaluation was made on relocation of Nanzheng County. In addition, the existing problems of relocation were concluded and the prospect of the county was discussed, which is of significance for relocation in Nanzheng County and even southern Shaanxi Province.展开更多
