- Abstract:
- The typical reclaimed land area in Huainan Coal Mine was chosen as the site. We used one-way ANOVA and Nemerow Synthetical Pollution Index to investigate the composition characteristics of humus and the status of heavy metals pollution in soil. The relationship between them was also discussed under different land use patterns (vegetable field, corn-wheat field, woodland and bare land). This study can provide the significant basis for remediation the reclaimed land. The results showed that the rank of humus contents, humification degrees and stability decreased in the order: vegetable field > corn-wheat field > woodland > bare land. The composition of soil humin (HM) was various under different land use patterns, the sequence of carbon content in humin composition was HMr > HMi > HMc. The contents of HM fractions significantly increased with application of organic fertilizer. The concentrations of Cu and Cd in soil from the reclaimed land were higher than those in the reference soil, while the concentration of Zn was lower than normal, the soils were in light pollution status. The organic fertilizer could be used to improve soil fertility. However, the contents of heavy metal in organic fertilizer should be controlled in terms of avoiding soil pollution.
