Research on urban landscape planning method based on GIS

The traditional urban landscape planning method for complex terrain and environment factor analysis is relatively vague, resulting in low planning efficiency and high spatial accuracy error. Therefore, a landscape planning method considering environmental pollution is proposed. Firstly, the geographic information system (GIS) technology platform is introduced. Through vector data and raster data, the terrain and terrain are analysed. Considering the light pollution of the garden night scene, the night scene lighting mode is designed, the influence of different light sources on the surrounding environment is analysed, plant species are analysed, and according to the characteristics of the plant landscape design, the design of urban landscape planning methods is completed. The experimental results show that the total score of the final design method is higher, and the spatial accuracy error is less than 4%, which verifies the feasibility of the landscape planning method.
