Optimal Grid Scale Estimation Method of Green Plant Distribution Pattern for Landscape Planning and Design

As an important part of urban ecosystem, green plants not only have multiple ecological functions such as beautifying the environment, purifying the air and regulating the climate, but also play an irreplaceable role in improving the quality of life and happiness of urban residents. However, how to rationally arrange green plants in landscape planning and design to achieve the best ecological and aesthetic effects has always been a difficult problem for urban planners and designers. Therefore, this paper puts forward a method for estimating the optimal grid scale of green plant distribution pattern for landscape planning and design. Design the technical route of landscape planning, according to the collinear equation, the data solution result of photogrammetry can be derived, the regional three-dimensional scene can be formed, the optimal objective function of ecological landscape planning model can be calculated, and the ecological landscape planning model can be constructed; in landscape planning and design, the best grid scale sampling of green plant distribution pattern is carried out to realize the best grid scale estimation of green plant distribution pattern. The experimental results show that the load balancing value of this method is small, and the balancing effect is good. The average allocation efficiency of green plant distribution pattern is 96.683%, which can effectively improve the allocation efficiency of the best grid scale estimation of green plant distribution pattern, and the layout of green plant distribution pattern is designed reasonably.
