Abstract: Optimising the layout of urban garden landscapes can effectively promote the improvement of garden landscape quality. Aiming at the problems of large fluctuations in spatial distribution separation and long planning time in existing planning methods, this paper uses discrete firefly algorithm to optimise the layout of urban garden landscapes. Firstly, a brightness optimisation model is constructed, and after discretisation, the optimal value range of the planning is determined. Then, determine the green content rate of the target area, and construct a green content model to calculate the plant compensation amount. Finally, taking the conflict degree and separation function as planning objectives, the optimal solution constraints are implemented to achieve layout optimisation. The experimental results show that the method in this paper can effectively reduce the separation of spatial distribution in gardens, and the planning time is always kept within 20 seconds, with good planning effect and efficiency.

Keywords: discrete firefly algorithm; landscape; layout optimisation; brightness optimisation model; separation function.
