Traditional garden culture carries deep historical heritage and national characteristics, while modern sculpture art embodies the spirit of the times and innovative ideas. The organic integration of the two is realized in the limited space of residential community, which not only maintains the spiritual kernel of traditional culture, but also meets the aesthetic needs of modern residents. Based on K-means clustering algorithm and morphology theory, this paper constructs a traditional cultural characteristic element extraction system, combines with modern sculpture design concepts, and puts forward the innovative design method of residential district landscape. The study collected 1,200 design samples through field research in six residential districts in Chengdu area, and established a cultural symbols transformation model by applying the theory of topological reconstruction. K-means and GMM algorithms were used for the comparative analysis of color feature extraction, and the clustering accuracy of Kmeans algorithm was 92.07%, which was better than 89.7% of GMM algorithm. Through 140 valid questionnaires, it was found that the landscape design scheme combining traditional cultural elements and modern sculpture scored 75.84 points, which was significantly higher than the 53.07 points of traditional landscape design, with an improvement of 42.9%. The research results show that the method of traditional cultural feature extraction based on cluster analysis and the integration of modern sculpture elements can effectively enhance the cultural connotation and aesthetic value of the landscape design of residential communities, and provide a scientific design method for the cultural inheritance and innovative development of the modern living environment.
