摘要
研究了徐州柳新采煤塌陷地充填复垦土壤的pH值和全氮全磷以及有效钾的特性 ,并对复垦土壤的分类进行了初步探讨。结果表明 ,该区充填复垦土壤受地下水碱性影响严重 ;全氮含量受复垦影响较大 ,含量低且变化无规律 ;全磷和有效钾含量变化不大。建议修改《中国土壤系统分类 (修订方案 )》中堆垫表层的定义 ,扩充其内涵 ;扩充人为新成土亚纲的内涵 ,增设堆垫人为新成土土类 ,下设粗骨堆垫人为新成土、紧实堆垫人为新成土、普通堆垫人为新成土亚类。
The PH value and characteristics of total Nitrogen,Phosphorus and effective Kalium as well as classification of soil on reclaimed land by filling in Liuxin coal mining-induced subsidence area,Xuzhou City are studied simply in the paper. The results show that: ① the soil there is heavily affected by underground alkaline water; ② total Nitrogen is fairly affected by land reclamation in content,which is low and has basically no law in its variation; ③ the contents of total Phosphorus and effective Kalium have no obvious variation. In view of the results,it is recommended to revise the definition of cumulous epipedon given in 'Classification of Soil System in China (Revised Version) ' and extend its connotation,which includes extending the connotation of subclass of anthropogenic entisols,adding the class of cumulous anthropogenic entisols and subclasses of skeletal cumulous anthropogenic entisols,compacted cumulous anthropogenic entisols and normal cumulous anthropogenic entisols under it.
