In the era of depopulation and global climate change, restoration of a sustainable society is an essential issue for realizing the national spatial strategies. A river catchment sphere is considered to be a suitable frame for planning a sustainable regional structure in which the socio-economic activities could be symbiotic to natural environment. Based on the geographic information system, a topographical correlation coefficient between river and road networks was analyzed to obtain a parameter for measuring symbiosis of social activities to natural environment. It was shown that indices regarding natural and social environments were well correlated with the proposed parameter, which suggests the present analysis would provides information useful for constructing restoration strategies of regions.
