摘要：中國的山地面積十分廣闊，山地城市的建設與發展具有重要的研究價值。重慶市是中國典型的山地城市，山地在城市建設中，既是城市發展的重要限制條件，也是城市形態的重要塑造條件。而南岸區中由長江水域至南山東山脊線這一區域則具有很強的山地城市代表性，具有地形地貌復雜、生態環境脆弱、歷史文化悠久等諸多特征。近年來區域城市的建設優化與山水環境的聯系愈加緊密，但由于山地城市的特殊環境，海拔與地形地貌條件成為城市進一步發展的關鍵影響條件。所以對城市景觀梯度特征的分析梳理，并探索各類要素對城市建設的影響具有重要意義。故本文以此區域為例，從景觀梯度與城市建設兩個角度出發，以遙感與實地數據為主，結合政府數據與學者研究，通過GIS、ENVI等軟件進行分析，分析各梯度景觀特征及其與城市建設的耦合關系。針對分析結果，提出了維護山地生態和諧、重建山地特色文化、打造獨特山地美學三項主要優化措施，希望為相關規劃與建設提供一些參考。

關鍵詞：山地城市；梯度；景觀；耦合

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.
