Abstract: Taking the reclamined soil area （forest land， rice-wheat rotation and cotton-soybean rotation） in the coal mining subsidence areas with high phreatic water level in Liuxin Town in Xuzhou City as an example，and compared with uncloapsed land （forest land，rice-wheat rotation and cotton-soybean rotation） with the same utilization methods，the variation characteristics of aggregate stability，particle distribution，fractal dimension and soil bulk density，compactness and porosity of reclaimed soil by different utilization methods are analyzed，besides that，effects of different land utilization methods on soil reclamation are discussed.The study results show that:①for 0~20 cm thickness of soil layer，compared with the non-subsidence area with the same utilization methods，contents of clay and coarse clay of cultivated layer of reclaimed soil are decreased significantly，compared with the unused subsidence land，contents of clay and coarse clay of reclaimed soil are both increased，in particular，contens of clay and coarse clay in the surface layer of rice-wheat rotation area are higher than others；②different land utilization methods have different degrees of improvement on the aggregate structure and properties of reclaimed soil，it can be described that it the number of wet aggregate larger than 0.25 mm in diameter and wet aggregate mean mass diameter （WMWD） are both increased，the percentage of aggregate destruction （PAD） will be decreased and stability of soil aggregate will be enhanced，improvement effects of rice-wheat rotation method to the structure of soil aggregate is better than others；③there is a close relationship between particles distribution，fractural dimension of reclaimed soil，number of wet aggregate larger than 0.25 mm，WMWD，PAD and soil bulk density，compactness and porosity，and soil fractal dimension is effective for indicating the structure and stability of soil aggregates.The above discussion analysis results could provide reliable reference for taking reclaimed soil quality restoration measures in the coal mining subsidence area with high phreatic water level.
