Abstract:: In this paper, Soil pH value, organic matter, available N, available P and available K of 33 soil samples obtained from 4 slopes protected by ecological protection technology of vegetation-growing concrete gunning were measured. The correlation between soil pH, organic matter and available nutrients were analyzed. The results showed that the pH values of soils ranged from 7.73 to 8.39 belonging to mild alkaline and alkaline soils. There were low and lower contents of organic matter ranging from 9.29 to 18.75 g/kg. The content of available N ranged from 34.34 to 46.10 mg/kg, available P ranged from 96.86 to 146.13 mg/kg, available K ranged from 196.98 to 333.53 mg/kg. The contents of available N belonged to a lower level, available K, P belonged to high levels in these 4 slopes. The correlation between pH and organic matter, available K was significantly negative, and the correlation between pH and available N, available P was positive; the correlation between organic matter and available N was significantly positive, and the correlation between organic matter and available K, available P was negative. It was showed that the contents of soil available nutrient affected by the pH value and organic matter of substrate of vegetation-growing concrete gunning.
