山地传统村落空间系统风险研究——以重庆为例

选取风险源、风险受体状态、风险响应三个方面16个指标，以外部自然、人文因素、传统村落内部景观和建筑结构等为切入点，构建山地传统村落空间系统风险评价体系，分析重庆市110个传统村落空间系统风险，并针对性地提出保护建议。研究表明：(1)构建的风险评价体系能够综合反映山地传统村落空间系统外部压力和内部脆弱性，体现其空间差异。(2)重庆市传统村落空间系统风险属较高及以上等级的有42个，占村落总数的1/3以上，主要分布于渝东南武陵山中山地区，如酉阳、秀山等地。(3)风险等级较高及以上的传统村落，应提升主体风险防范能力，合理规划村落发展，避免城镇边界扩张挤压传统村落空间，导致其非自然性衰落。山地传统村落空间系统风险研究从宏观揭示风险驱动因子，识别风险胁迫大小，对传统村落精准保护具有重要意义。

RESEARCH ON THE TRADITIONAL VILLAGES SPACE SYSTEM RISK IN MOUNTAIN AREAS:A CASE STUDY OF CHONGQING

Chinese traditional villages endows thousands years of farming civilization, which are the historical testimony of ancestors being in harmony with nature. And taking external natural, humanistic factors, traditional village landscape and building structure as the entry point, the article developes a spatial system risk system to assess traditional villages in mountain area, and the spatial system risk of 110 traditional villages in Chongqing is analyzed with the help of order improvement, geographic detectors and other methods, and targeted protection suggestions are put forward. The research shows that: 1) The traditional villages spatial system risk evaluation index system constructed can comprehensively assess the external pressure and internal vulnerability of the mountain traditional villages. Spatial system, and its spatial distribution differences are expressed. 2) There are 42 traditional villages with a high or above level risk in Chongqing, accounting for more than one-third of the total number of traditional villages, which are mainly located in the Wuling mountain region of the southeast Chongqing, such as Youyang and Xiushan county. 3) For traditional villages in high and above level risk, the capabilities to resist the risk should be improved, and the development of the traditional village should be planned rationally to avoid the expansion of the urban boundary erodes the space of the traditional village, leading to its decay.
