Journal of E-Technology Qing Zeng 16 1 2025 https://doi.org/10.6025/jet/2025/16/1/10-18 https://www.dline.info/jet/fulltext/v16n1/jetv16n1_2.pdf This paper focuses on the optimization design of the green architecture landscape space environment in traditional villages using the niche genetic algorithm. The purpose is to explore how to improve traditional villages’ green architecture landscape space environment through optimization design methods. By analyzing the cultural characteristics and environmental issues of traditional villages and combining domestic and foreign research progress, a niche genetic algorithm-based optimization design method is proposed. Experimental results demonstrate that this method effectively enhances traditional villages’ green architecture landscape space environment, thereby improving the residents’ quality of life and environmental adaptability. This research provides a new approach and method for the sustainable development of traditional villages.
