With the progress of the industrial revolution and the development of modern science and technology, China's urbanization process has been promoted. Urban and rural economic and social construction has greatly improved the local appearance and social structure. Human activities and natural ecology have affected the whole geological-ecological process, further aggravated the geological-ecological damage, and caused more serious geological disasters, especially in some places (especially in mountainous areas). In recent years, strong geological disasters have occurred in Wenchuan, Yushu, and Lushan regions of China, which not only seriously endanger the life safety and social life of the affected people, but also damage the geological-ecological structure and social functions of the region, especially in the geographically sensitive Alpine urban areas. It also produced many secondary disasters, such as landslides and land collapses. Mountainous cities and towns have special requirements for construction land, which is difficult to construct. Industrial land resources are in short supply, urban and rural comprehensive construction land is not active, and cultivated land area resources are tight. Compared with plain towns with superior geological conditions, mountain towns are more vulnerable to adverse geological environment such as geological ecology, landform, ecological vegetation, and hydrology. The geographical natural environment, as an organic whole that combines and interacts with the geomorphic natural environment, the biological-ecological environment, and the human social management environment, is the main reason that affects the development of mountain towns. Once the mountain geological ecology is destroyed, a series of geological disasters will often be induced, which will seriously restrict the healthy development of mountain towns. Scientific management of the geological environment plays an important role in the assessment of the geological environment restoration of mountain towns after disasters. Therefore, taking the most beautiful counties in China, Baoxing City, and Tianquan County as examples, on the basis of studying the complex geological-ecological theory of geological disasters, this paper further improves the traditional ecological footprint model in China, and using the interval direct fuzzy information constructs the metric index of ecological restoration scheme of mountain towns, and determines the evaluation index and optimal scheme of ecological restoration. From the aspects of landscape layout construction, disaster prevention and mitigation planning and improvement, and environmental restoration project, the future geoecological restoration and response strategy of Lushan County are pointed out, which provide guidance for the postdisaster geoecological safety layout construction.
随着工业革命的进步和现代科学技术的发展，中国的城市化进程得到了推进。城乡经济社会建设极大地改善了当地的面貌和社会结构。人类活动和自然生态影响了整个地质-生态过程，进一步加剧了地质生态破坏，引发了更严重的地质灾害，特别是在一些地方（特别是山区）。近年来，中国汶川、玉树、庐山等地区发生了强烈的地质灾害，不仅严重威胁着受灾人民的生命安全和社会生活，还破坏了区域的地质-生态结构和社会功能，特别是在地理敏感的高山城区。它还产生了许多次生灾害，如滑坡和崩塌。山地城镇对建设用地有特殊要求，难以建设。工业土地资源短缺，城乡综合建设用地不活跃，耕地面积资源紧张。与地质条件优越的平原城镇相比，山地城镇更容易受到地质生态、地形、生态植被和水文等不利地质环境的影响。地理自然环境作为与地貌自然环境、生物-生态环境和人类社会管理环境相结合并相互作用的有机整体，是影响山地城镇发展的主要原因。一旦山地地质生态遭到破坏，往往会引发一系列地质灾害，严重制约山地城镇的健康发展。科学管理地质环境对灾害后山地城镇地质环境恢复的评估起着重要作用。因此，本文以中国最美县城宝兴县和天全县为例，在研究复杂的地质灾害地质生态理论的基础上，进一步改进了中国传统的生态足迹模型，利用区间直接模糊信息构建了山地城镇生态恢复方案的度量指标，并确定了生态恢复的评价指标和最优方案。从景观布局建设、防灾减灾规划和改善、环境恢复工程等方面，指出了庐山县城未来的地质生态恢复和应对策略，为灾后地质生态安全布局建设提供了指导。
