The Optimization of Spatial Art Pattern of Vegetation Landscape in the Bay Area

Vegetation landscape is the basic landscape unit of the coastal city park green space. The optimization of its spatial pattern is conducive to improving the urban ecological environment and beautifying the living environment. Therefore, in order to improve the efficiency of spatial pattern optimization, a method of spatial pattern optimization of bay vegetation landscape based on AHP is proposed. Methods firstly, the data were obtained through literature reading, field investigation and questionnaire survey. Then, the evaluation of vegetation community allocation mode was carried out by using AHP. Finally, under the guidance of spatial optimization objectives, combined with the principle of landscape pattern optimization, the optimization design of vegetation landscape spatial pattern in the Bay was carried out. The results show that: under the application of this method (improved AHP), the three index values of water loss, sediment loss and culvert water volume are better than those of the conventional beauty evaluation method (SEB) and semantic analysis method (SD), which proves the vegetation landscape spatial pattern scheme designed by this method More reasonable and scientific, to achieve the purpose of optimization.
