城市色彩景观合理布局优化设计仿真研究

摘要

This research focuses on the model for optimization design of rational distribution of urban color landscape based on multi-dimensional feature parameter.The research used chaos method with variable scale to build static evaluation model for rationality of urban landscape state and extracted the optimal feature parameter weight of accessibility of landscape spatial pattern,then confirmed the index system of the optimization design and graded quantization qualitative index in evaluation system integrated with fuzzy evaluation criterion.The research also calculated its comprehensive evaluation value and carried out consistency check for index weight of the rationality of color landscape.Simulation results show that the method has higher evaluation precision and can provide effective basis for improving urban ecological environment.%对城市色彩景观合理布局优化设计,可以提高改善和提升城市经济与生态功能.进行景观布局设计时,应组建城市景观状态合理性静态评价模型,提取最佳的城市色彩景观空间格局的可达性特征参数权重,但是传统方法利用构建的城市色彩景观合理性生态美学评价指标体系进行布局设计,无法计算出城市色彩景观合理性特征最佳权重,存在设计效果差的问题.提出一种基于多维特征参数的城市色彩景观合理布局优化设计模型.上述模型先采用变尺度混沌方法组建城市景观状态合理性静态评价模型,提取最佳的城市色彩景观空间格局的可达性特征参数权重,确立城市色彩景观合理性布局优化设计指标体系,融合于模糊评价标准对评价体系中的量化定性指标进行评分,并对色彩景观合理性指标权重进行计算和一致性检验,并计算其计算综合评价值,并组建城市色彩景观合理布局优化设计模型.仿真结果表明,所提方法评价精确度高,可以为改善城市生态环境提供有效依据.
