Abstract: The analysis of rural settlements and the water and soil coupling situation in mountain area is helpful to highlight the advantages and characteristics of rural mountain area and promote rural vitalization. With a case study of mountain area in Fuzhou, the spatial distribution characteristics of rural settlements in mountain area and water and soil coupling situation were analyzed based on GIS and spatial coupling correlation model. The results show that: (1) To the year of 2015, there were a total of 5232 rural settlement patches in Fuzhou mountain area, featured in large numbers with small scale, and mainly distributed in the area below 650m of altitude. (2) The rural settlements in each town area showed spatial pattern characteristics of "gather in center as well as diffuse toward north-south " with agglomeration distribution and differentiation. (3) There was a good coupling situation between settlements and cultivated land but less satisfactory coupling with water system, showing obvious "farmland directivity" and small-scale "water system directivity", without obvious correlation with the road. The influence of cultivated land and water resources on villages and towns showed strong spatial heterogeneity, and soil and water resources have become an important factor restricting the development and transformation of rural settlements in Fuzhou mountain area.

Key words: rural settlement, spatial pattern, soil and water resources, spatial coupling, Fuzhou
