Fractal Analysis on Spacial Structure of Land Use in Ning-Zhan-Yang Hilly Area——A Case Study of Zhenjiang

Based on the data of Zhenjiang land use status,using fractal theory and the GIS spatial analysis method,the land use fractal characteristics of Zhenjiang hilly area was analyzed and discussed.Some conclusions were drawn as followings.In general,the fractal characteristics of spacial structure of land use is significant in Zhenjiang,all the land-use types have fractal characteristics and the fractal dimension D values vary from 1.075 to 1.234,the descending order of land use types fractal dimension is water body,forestland,construction land,other agricultural land,garden land,cultivated land;while the descending order of stability indices is cultivated land,garden land,other agricultural land,construction land,forest land,water;40 percent of areas hold the stability indices form 0.2 to 0.4,which shows the total stability is in a bad condition.The land use of the fractal dimension and stability index of three regions of Zhenjiang is much different,the same land type fractal dimension and stability index in different areas are different.Cultivated land and forestland fractal features present diversity characteristics in the west of hilly region and the east of plain region,construction land and water body space structure stability is low and the complexity is high in the east of plain region.Fractal dimension can be used as an effective index in the researches for land use structure in the hilly area.
