Abstract:

Based on the building information of 6 streets in Zhongshan District of Dalian City,the building landscape index is selected and ArcGIS spatial statistics and multi-distance spatial clustering analysis method is used to study the spatial pattern of architectural landscape in 10 years. The results showed that:(1) From 2003 to 2013,the landscape of the street buildings gradually expanded from horizontal to vertical space, in which Qingniwaqiao street, Renminlun street and Haijunguangchang street changed obviously. (2) When the scale is 928.68 m, the spatial distribution of the four types of buildings are clustered. When it is more than 928.68 m, the spatial aggregation degree of the ultra-tall buildings decreases in 2003. By 2013, high-rise buildings with the increase in the scale of aggregation gradually reduced, low-rise buildings, multistory buildings and ultra-tall buildings in the spatial distribution of a certain aggregation state.

Key words: multi-distance spatial cluster analysis, architectural landscape index, spatial-temporal differentiation, Zhongshan district
