Abstract: In view of the multi-dimensional inactivation problem faced by traditional villages， this paper deeply analyzes the composition of their active factors and identifies the key factors affecting inactivation， which can provide theoretical support and practical pathways for the sustainable development of traditional villages. Based on the regional characteristics of three traditional villages in Shendu Town， Huizhou District， Huangshan City， Anhui Province， a dynamic evaluation system covering three levels and containing thirty-two evaluation indicators was established. The results show that： 1） There is a certain degree of inactivation in the three villages， with some differences in the degree of inactivation. Although all are at the level of “micro-inactivation”， the degree of inactivation in Miantan Village is relatively light. 2） Factors such as cultural heritage protection， social governance， and economic development have a high contribution to living development， which significantly influences the active development of villages. In terms of inactivation index， the spatial characteristics of villages， cultural heritage protection， and economic development account for a prominent proportion and have a significant impact on inactivation. This shows that the development of traditional villages in Shendu Town area of She County is closely related to cultural heritage protection and economic development. 3） From the perspective of the total active score， Miantan Village （72.6）> Jiusha Village （71.4 >Huaiyuan Village （64.9） ， which is consistent with the survey data. This study demonstrates that village deactivation is caused by a combination of factors. Therefore， the key to promoting village revitalization and achieving sustainable development lies in establishing a living and sustainable conservation and development mechanism.
