Interpretation of Sustainable Spatial Patterns in Chinese Villages Based on AHP-GIS-FCE: A Case Study of Chawan Village, East Mountain Island, Taihu Lake, Suzhou

To address the dilemma of China’s rural areas becoming increasingly homogeneous due to large-scale, campaign-style rural construction. This study proposes an innovative rural spatial pattern evaluation model that integrates geomancy theory with modern spatial analysis methods. Chawan village, Suzhou city, Jiangsu Province, China, is used as the study area, with the aim of better assessing and optimizing rural spatial patterns in China. The Analytic Hierarchy Process (AHP) is a method for ranking factors based on their relative importance, which is used to assign weights to indicators. Combined with the fuzzy comprehensive evaluation (FCE) method based on fuzzy set theory and ArcGIS weighted overlay analysis, it is used for evaluating rural spatial patterns. The results show that natural environmental indicators hold more weight than artificial ones. Among these, water body landscapes (0.111), water body buffer zones (0.103), and vegetation ecology (0.073) are the highest weighted indicators. The top three spatial pattern evaluation values are landscape environment (3.85), water bodies (3.52), and vegetation (3.51). The final result for the village is moderate, with an evaluation score of 3.385. This result suggests that the rural spatial pattern has a solid foundation for cultural continuity and significant potential for optimization, particularly in ecological and water body features. The AHP–GIS–FCE multi-method evaluation framework provides an effective tool for assessing and optimizing rural spatial patterns. This approach offers a systematic solution for rural development, promoting localized and diverse planning models, as opposed to the homogenized “one-size-fits-all” approach, and contributes to the protection of cultural heritage and sustainable development.
