Chinese traditional settlements are of vital importance in ecological and cultural protection. are is also interesting subjects of study for sustainability science and trans-disciplinary research efforts. In this study, Chinese traditional Feng-shui theory and modern landscape pattern theory were combined to analyze the Zhagana settlement from multiple viewpoints. Stereoscopic structure, ecological elements, and spatial pattern were examined in order to explore the ecological rationality and internal driving forces embodied in the ideal landscape type, and to try to understand the interaction between culture and environment in settlement development. Feng-shui mode analysis indicates that the Zhagana settlement is a typical 'World-in-Pot' mode with 'Basin-Gap-Corridor' structure, which has the 'mountain-forest-village-river-forest' structure of the ideal Chinese landscape. With human architecture as the center, the landscape has an ecological circle structure on both horizontal and vertical levels. The overall ecological and geographic conditions coincide with the principle of 'Cang-feng De-shui' in ancient Chinese Feng-shui theory. With similar interface characteristics between each village, four whole villages concentrate around the Lasang Temple. Landscape pattern index analysis indicates that forestland and hill dryland compose the matrix of the settlement landscape. The diversity and evenness of the whole landscape are high. With low artificial patch area proportion, Zhagana is characterized by extremely sparse settlement, and human disturbance of the environment is very low. Results of the study indicate that formation of the ideal landscape pattern in the Zhagana settlement is mainly driven by the interactions between cultural and environmental forces. This study establishes a foundation for the Zhagana settlement's protection and development. It also has both theoretical significance and practical value for research on cultural-environmental interactions and the Chinese multifunctional landscape model.
