2.3. Research Methods
- (1)
- Use administrative boundaries to clearly define the geographic scope of this study.
- (2)
- Employ ArcGIS 10.7 to delineate the boundary of Yuqian Town and all villages under its jurisdiction. This ensures that the landscape character zoning outcomes are integrally linked to and supportive of spatial planning efforts [25], facilitating direct applicability to urban development strategies.
- (1)
- Classify natural, cultural, and visual variables into grid cells of 70 m × 70 m.
- (2)
- Conduct a two-step cluster analysis using SPSS.
- (3)
- Utilize eCognition software to integrate and delineate landscape character subareas.
- (4)
- Make manual adjustments after the analysis to refine the zoning accuracy.
- (1)
- Integrate landscape character areas with administrative village boundaries through overlay analysis.
- (2)
- Develop a comprehensive plan for landscape character management zones.

Clustering Method | Core Characteristics | Advantages | Limitations | Applicable Scenarios |
---|---|---|---|---|
K-means Clustering | Targets continuous variables, optimizes cluster centers through iteration, requires preset number of clusters. | Simple operation, high computational efficiency, flexible adjustment of grid size and cluster number. | Sensitive to noise and outliers; relies on initial cluster centers; only suitable for continuous variables. | Preliminary clustering of large-scale continuous data. |
K-modes Algorithm | Focuses on categorical variables, uses mode instead of mean to calculate cluster centers, reduces sensitivity to noise. | Better performance for categorical data than K-means; less dependent on cluster shapes. | High requirements for initializing cluster centers; still limited to categorical variables. | Clustering of pure categorical landscape features. |
K-prototypes Algorithm | Integrates K-means and K-modes, supports mixed clustering of continuous and categorical data. | Handles multi-type variables; strong robustness. | Complex implementation in Python; requires manual construction of evaluation metrics; inherent limitations in clustering ordering. | Comprehensive landscape classification with mixed variables. |
Affinity Propagation (AP) Algorithm | Eliminates the need for predefined initial cluster centers, determines cluster centers via message passing. | Reduces dependency on prior knowledge; wide applicability. | Requires manual tuning of key parameters (e.g., damping factor), affecting cluster number and convergence. | Exploratory clustering without prior information. |
Two-step Clustering Algorithm (This Study) | First performs K-means clustering on continuous variables, then hierarchical clustering on categorical variables, automatically determines optimal cluster number. | Simultaneously processes continuous and categorical variables; quantifies cultural landscape variables; enhances weight of categorical variables in results; no manual parameter tuning needed. | Slight loss of precision for extremely fine-grained data (balanced by 70 m grid in this study). | Accurate delineation of multi-dimensional landscape characteristics in mountainous small towns |
