Abstract：A thorough understanding of the relationship between road network and land use will help to develop sustainable land use and road network planning. This paper introduced the multiple centrality assessment model of closeness, betweenness and straightness, by using the UNA to measure the road network centrality in Hubei province, then we selected four landscape metrics including the percentage of landscape, Shannon diversity index, mean patch size, and the mean shape index to quantify the landscape pattern. Spearman rank correlation was employed to explore the relationship between road network and the land use. The results showed that: (1) there were different spatial patterns of centrality in Hubei province, higher value of centrality always emerges in the east while the lower value always in the west. The closeness showed ribbon distribution and the betweenness displays porously, however, the straightness presented a patchy pattern; (2) at landscape level, the landscape fragmentation and diversification were mostly sensitive to the straightness, but relatively complex with the closeness and betweenness; (3) at class level, the relationship between road centrality and the landscape patterns of various land-use types differ greatly. Specifically, the area with centrality advantages showed strong rejection and fragmentation effect to forest land-use while turns out to be strong attraction and agglomeration phenomenon to construction land-use. These findings provide a new perspective to the regional spatial form and its composition and its related factors through discussing the relationship between road network centrality and land use pattern.
