Architectural landscape architecture design exhibits complexity and diversity, relying on the continual growth of computer and digital technologies and influenced by programming linguistics, complexity theory, chaos theory, non-Euclidean geometry, system theory, and emergence theory. Architectural landscape projects are becoming increasingly complicated, and parametric design methodologies have played a significant role in this process. Following modernism and postmodernism, this might be the start of a new design revolution fueled by technological advancements. Simultaneously, the landscapes created by these parametric design processes have a very high degree of convergence. The purpose of parametric design is to parameterize the design's outcome. A certain component that influences things is discovered through analysis, and then they are qualitatively and quantitatively assessed for data. The arithmetic unit is used to substitute the varied values of the influencing information components to construct the technique of different information models of the output, and the computer is used to compile the programme to form the internal connection with the outcome.
