Shanghai Chenshan Botanical Garden, the typical green space for properties degradation was chose as a field test to research the effects of different ratios of soil amelioration. The results indicated that the soil physical properties of all treat- ments improved better, especially the treatment which was made from soil, greenery waste and organic fertilizer in the volume ratio of 8︰3︰0.8 and gypsum with 0.5 kg/m3 was added. This treatment could get the lowest bulk density, the highest content of water, saturate water, field capacity, non-capillary porosity, capillary porosity and available water, and the better saturated hydraulic conductivity. During the time of 30d, 90d and 180d after experiment, the soil physical properties of the same treatment changed little and the soil water characteristic curves of all treatments fit the Gardner model well (R2 >0.9). Although sand could get better saturated hydraulic conductivity, it could not get comprehensive soil physical properties as organic materials just like greenery waste or peat. With the experiment time extension, using desulfurized gypsum could get better results to improve soil physical properties. Among all kinds of soil amelioration, the mixed application of organic matters and desulfurized gypsum could get good result.
