Analysis on Land Use Structure and Spatial Distribution in Donggang District of Rizhao City

By using land use diversification index,concentration index and the combination of types of land use,land use structure in Donggang district is analyzed in this paper.By using dominance index and evenness index as an index to measure spatial layout of land use,land use structure and spatial distribution in Donggang district are analyzed quantitatively.It is regarded that concentration levle of land use in this area is rather low,and the total function of land use is not high.It will provide basis for spatial distribution and optimization of land use.
