Abstract: Fragmentation of the land covers and land use comprises both the area and patch dimensions. In the present study, we have employed the Gibbs-Martin (GM) diversification index in order to determine the diversification in rapidly urbanizing Ranchi city, capital of Jharkhand state, India, considering both the area and patch dimension of the different land use and land covers present in the area. Comparative analysis of the area and patch based GM index shows significant difference in the magnitude and pattern of the GM index scores determined for the 30 successive spatial buffers of 100m interval delineated around the major roads in the study area. The land use and land covers were mapped from the Landsat ETM data of 2013. The results demonstrated that it is judicious to consider both the area and patch dimension of the fragmenting land use and land covers to construct accurate inference about the land use and land cover diversification in an area that could serve as vital information for the urban planners.
