Abstract: An urban green spatial layout coupling reconstruction system based on remote sensing analysis is designed to deal with the problem that the traditional spatial layout reconstruction system cannot locate urban green space accurately. The hardware part of the system is designed, which is composed of the remote sensing image acquisition module and data transmission module. On the basis of the hardware part, the compressed images are preprocessed in the software part. The image features are analyzed and extracted by means of the remote sensing analysis technology, so as to obtain green spatial layout information. The urban green spatial layout is reconstructed according to the analysis results to complete the system design. The comparison testing results verify that, in comparison with the traditional layout reconstruction system, the system designed based on the remote sensing analysis technology can locate urban green space more accurately.

城市绿色空间是为了解决城市化所带来的一系列影响城市居民健康等新问题而提出的全新概念。随着城市的不断发展,城市绿地面积不断减少,改变了原有绿色空间布局的同时,也加重了生态环境的负担。合理的城市绿色空间布局不仅能够改善生态环境,保护和维持生态多样性,还能调节现今社会的快节奏生活[1?2]。因此,城市绿色空间的合理布局有利于城市的发展。
本文将设计基于遥感分析的城市绿色空间布局耦合重构系统,设计的目标是对城市绿色空间合理布局,并對已经改变的空间布局耦合重构。本文设计的系统由硬件和软件两部分组成,利用遥感分析方法处理系统硬件部分采集的二维城市空间布局图像,在软件部分使用小波分解等算法实现对城市绿色空间布局的耦合重构。……
