摘要：中国的山地面积十分广阔，山地城市的建设与发展具有重要的研究价值。重庆市是中国典型的山地城市，山地在城市建设中，既是城市发展的重要限制条件，也是城市形态的重要塑造条件。而南岸区中由长江水域至南山东山脊线这一区域则具有很强的山地城市代表性，具有地形地貌复杂、生态环境脆弱、历史文化悠久等诸多特征。近年来区域城市的建设优化与山水环境的联系愈加紧密，但由于山地城市的特殊环境，海拔与地形地貌条件成为城市进一步发展的关键影响条件。所以对城市景观梯度特征的分析梳理，并探索各类要素对城市建设的影响具有重要意义。故本文以此区域为例，从景观梯度与城市建设两个角度出发，以遥感与实地数据为主，结合政府数据与学者研究，通过GIS、ENVI等软件进行分析，分析各梯度景观特征及其与城市建设的耦合关系。针对分析结果，提出了维护山地生态和谐、重建山地特色文化、打造独特山地美学三项主要优化措施，希望为相关规划与建设提供一些参考。

Abstract: China's mountainous area is very vast, and the construction and development of mountain cities are of great research value. Chongqing is a typical mountain city in China. In urban construction, mountain is not only an important limiting condition for urban development, but also an important shaping condition for urban form. However, the area from the Yangtze River to the east ridge line of Nan Mountain in Nanan District has a strong representation of mountain cities with complex landform, fragile ecological environment and long history and culture. In recent years, the construction and optimization of regional cities are increasingly closely related to the landscape environment. However, due to the special environment of mountain cities, altitude and landform conditions become the key influencing conditions for the further development of cities. Therefore, it is of great significance to analyze the gradient characteristics of urban landscape and explore the influence of various elements on urban construction. Therefore, this paper takes this region as an example, starts from two perspectives of landscape gradient and urban construction, focuses on remote sensing and field data, combines government data and scholars' research, and analyzes the characteristics of landscape gradient and its coupling relationship with urban construction through GIS, ENVI and other software. In view of the analysis results, three main optimization measures are proposed to maintain the ecological harmony of mountainous areas, rebuild the characteristic culture of mountainous areas and create the unique mountain aesthetics, hoping to provide some references for relevant planning and construction.
