This paper studies and analyses the formation and evolution of the urban spatial pattern of Harbin, a waterfront city in northern China. Considering the history and culture of this city, as well as the impetus of modern urbanization, and performing Pearson's correlation analysis it is concluded that the modelled social vulnerability score and the flood damage in certain periods are highly correlated. The results indicate, 1. that the change of spatial pattern and the social vulnerability to disasters are in a high coupling relationship, 2) that the social vulnerability is closely related to the terrain of the disaster source, and the urban civilians, handicraftsmen and businessmen in Daoli District and Daowai District of the first stage of terrain are the population with the highest social vulnerability, and 3) that there is no apparently time-varying change of socially vulnerable groups. This paper innovates to combine the research on the dynamic change of the urban spatial pattern and the research on social vulnerability, in order to supplement and perfect the assessment system for social vulnerability influencing factors, and to provide reference for the establishment of the social policy as relevant.

Abstract


This paper studies and analyses the formation and evolution of the urban spatial pattern of Harbin, a waterfront city in northern China. Considering the history and culture of this city, as well as the impetus of modern urbanization, and performing Pearson's correlation analysis it is concluded that the modelled social vulnerability score and the flood damage in certain periods are highly correlated. The results indicate, 1. that the change of spatial pattern and the social vulnerability to disasters are in a high coupling relationship, 2) that the social vulnerability is closely related to the terrain of the disaster source, and the urban civilians, handicraftsmen and businessmen in Daoli District and Daowai District of the first stage of terrain are the population with the highest social vulnerability, and 3) that there is no apparently time-varying change of socially vulnerable groups. This paper innovates to combine the research on the dynamic change of the urban spatial pattern and the research on social vulnerability, in order to supplement and perfect the assessment system for social vulnerability influencing factors, and to provide reference for the establishment of the social policy as relevant.
