摘要
乡村建筑群的无序发展已经严重阻碍乡村规划建设,需要对现有的乡村高密度建筑群进行密度评估,完成合理规划。为了有效提高规划效果,基于树形结构模拟方案,提出了一种新型的高密度建筑群规划方法。首先应用树形结构模拟算法,基于多分辨率乡村建筑差分图像的定理分布,完成拟合度最佳值求取,确定当前检验参数,判别不同样本图像分布函数的匹配度,从数学角度即根据应用积分均方误差的形式获取当前建筑差分图像宽窗最优值,提高建筑密度函数图像曲线的平滑度,降低宽窗拟合引起的密度规划精确度损耗,采用GK核函数,作为初始函数用最优宽窗值,求取建筑密度函数规划结果,实现对乡村高密度建筑最终的评估规划。经过分析实验可以确定,由于提出的规划方法因为加入了多项寻优程序,有效提高了乡村建筑群密度合理性,实现了乡村建筑有序规划。
The disordered development of rural buildings has seriously hindered the rural planning and construction. It is necessary to evaluate the density of the existing rural high-density buildings and complete the reasonable planning. In order to improve the planning effect, a method of planning high-density building was proposed based on tree structure simulation. Firstly, the tree structure simulation algorithm was adopted based on the theorem and distribution of multi-resolution difference image of rural construction, the optimal fitting degree was calculated to determine the current test parameters. After identifying the matching degree of distribution functions of different sample images mathematically, integral mean square error was adopted to find the optimal window width value of difference image, so as to improve the smoothness of image curve of density function and reduce the density planning accuracy loss caused by window width fitting. Moreover, GK kernel function was taken as the initial function, and the optimal window width value was used to calculate the building density function planning result. Finally, the evaluation planning of high-density buildings in rural areas was completed. Through analysis and experiment, it can be seen that the proposed method effectively improves the rationality of density of rural buildings and realizes the orderly planning of rural buildings due to the introduction of multiple optimization procedures.
