The study on the summarizing of models and influencing factors in the process of village ecological construction is of great theoretical and practical significance to promote the coordinated development of regional ecological, social and economic systems. In this study, the important area of water conservation and biodiversity protection in Daloushan mountains (hereinafter referred to as "Daloushan area") was taken as the research object, and the Principal Component Analysis (PCA) was applied to study the influencing factors of its villages and townships′ ecological construction, and its villages and townships' ecological construction mode was studied through the ideas of "binding points with area" and "from point to area". The results show that: 1) The ecological construction of villages and townships in the Daloushan area is influenced by the combination of human settlements factors (A1), economic development factors (A2) and ecological environment factors (A3), of which the role of A2 is the most significant, among the 16 typical villages and townships selected in the Daloushan area, the villages construction of Loushanguan subdistrict (T5), Bing′an Township (T8), Tiantai Township (T9), Maotai Township (T13), Heishu Township (T14), Yile Township (T15) and Shuitian Township (T16) is more significantly influenced by the ecological environment factor (A3), the human settlement environment factor (A1) and economic development factor (A2) also have significantly effects on Loushanguan subdistrict (T5) and Maotai Township (T13); 2) The ecological construction of villages and townships in the Daloushan area includes four paths and twelve modes, which are developing ecological economy to boost rural revitalization (L1), restoring lucid waters and lush mountains to activate rural revitalization (L2), improving human living environment to empower rural revitalization (L3), and innovating institutional mechanism to consolidate rural revitalization (L4). The above research results are of great significance to promote ecological construction and rural revitalization in the Daloushan area, and also provide demonstration cases for the construction of beautiful villages nationwide.
