Artificial Intelligence (AI) is emerging as a transformative technology in landscape design, offering innovative solutions for planning, visualization, resource management, and maintenance of outdoor spaces. By integrating machine learning, deep learning, computer vision, robotics, and remote sensing technologies, AI enhances the efficiency, sustainability, and creativity of landscape architecture. AI-driven tools enable accurate site analysis, intelligent plant selection, climate-responsive garden design, automated irrigation, disease detection, and robotic maintenance. Advanced applications such as generative design, virtual reality, and adaptive landscapes allow designers to create personalized and environmentally resilient landscapes. Studies have demonstrated the potential of AI in improving garden intelligence, reducing energy consumption, optimizing resource use, and supporting sustainable rural and urban landscape development. As technology advances, AI is expected to play a vital role in creating smarter, greener, and more adaptive landscapes that meet future environmental and societal challenges.
