Title: Soil Nutrient Status of Excavating Coal Subsidence Region in Huaibei City
Abstract: The soil nutrient contents of three land use types in Huaibei excavating coal subsidence region were studied.The results showed that total nitrogen content of Nanhu wetland soil intensely disturbed by human activities was 1.128 g/kg,which was significantly higher than green space and showed no significant difference between nondisturbed Donghu wetland and cultivated land.The soil organic content of Nanhu wetland was 23.781 g/kg,that of Donghu wetland was 11.25 g/kg.There was no significant difference in the soil organic content between two wetlands,but they were marked higher than green space and cultivated land.Cultivated land total potassium content was 18.864 g/kg,which was significantly higher than 16.02 g/kg in green space,and the total potassium content in wetland lay between green space and cultivated land.Three land use types had no apparent difference in soil total phosphorus(0.584~0.773 g/kg) and pH(8.35~8.74).The analysis of soil nutrient variation coefficient indicated wetland soil pH variation was weak,the other soil nutrients were medium,and all soil nutrients of cultivated land and green space belonged to weak variation.Nanhu wetland had higher variation coefficients in all soil nutrients than Donghu wetland,except the variation coefficient of total potassium content which had the same value in two wetlands.
