摘要
针对传统景观布局规划方法存在对生态环境烟尘与二氧化硫的改善效果不理想、且规划精细度偏低的问题,提出新的城市生态景观色彩平衡性布局最优规划方法。通过色彩平衡原理描述生态景观的色彩空间,建立景观要素转移矩阵获取多样性指数,通过构建景观类型分维值模型得到景观分维度,定量化获取地形和景观结构特征之间关系。在此基础上利用纹理特征分析城市生态景观图像,基于最大似然法对生态景观数据进行分类,实现生态景观布局的最优规划。仿真结果表明,研究方法下城市环境烟尘和二氧化硫含量均呈现逐年递减状态,说明生态景观色彩平衡规划具有良好效果,能够改善生态环境质量问题。
In traditional landscape layout planning method,the improvement effect for the ecological environment smoke and sulfur dioxide is not ideal,and the planning fineness is too low.Therefore,an optimal planning method for color balance layout in urban ecological landscape was proposed.The color space of ecological landscape was described by the principle of color balance.The diversity index was obtained by establishing the landscape element transfer matrix.The fractal dimension of landscape was obtained by constructing the model of fractal value of landscape type.The relationship between topography and landscape structure feature was obtained quantitatively.On this basis,texture features were used to analyze the urban ecological landscape image.Based on the maximum likelihood method,the ecological landscape data was classified.Thus,the optimal planning for ecological landscape layout was achieved.Simulation results show that the content of smoke and sulfur dioxide in urban environment is decreasing year by year,so the proposed method has good effect and can improve the quality of ecological environment.
