摘要

针对传统城市景观格局空间分布研究方法中特征提取效率低的问题，提出了一种基于多源遥感技术的城市景观格局空间分布研究新方法。结合信息熵和网格划分思想，利用多源遥感技术完成城市景观格局的空间二次网格划分。根据二次网格划分结果，计算城市景观格局空间分布的概率密度。建立尺度金字塔，研究城市景观格局的空间分布特征。实验结果表明，该方法能够有效地实现城市景观格局空间分布特征的研究，特征提取效率高，最大提取时间仅为0.22 min。

Spatial distribution characteristics of urban landscape pattern based on multi-source remote sensing technology

In order to overcome the low efficiency of feature extraction in traditional research methods for spatial distribution of urban landscape pattern, a new research method based on multi-source remote sensing technology is proposed. Combined with the idea of information entropy and grid division, the spatial secondary grid division of urban landscape pattern is completed by multi-source remote sensing technology. The probability density of spatial distribution of urban landscape pattern is calculated according to the results of secondary grid division. The scale pyramid is established to study the spatial distribution characteristics of urban landscape pattern. The experimental results show that the proposed method can effectively realise the research of spatial distribution characteristics of urban landscape pattern, with high efficiency of feature extraction, and the maximum extraction time is only 0.22 min.
