摘　　要：通过对中原油田污染耕地的现场调查和几种污染因素的比较,发现油田高矿化度产出水腐蚀穿孔是造成弃耕地土壤污染的主要原因。污染土壤含盐量为7.07g·kg-1、可溶性Na+和Cl-为9.39和11.56cmol·kg-1,是未污染土壤的6.0、7.8和18.1倍。由于土壤盐分和可溶性Na+含量高,造成了土壤板结、紧实,使土壤生态环境退化和恶化。A survey was conducted to show the origin of pollution resulting in farml and abandoned in the Central Plains Oil Field. It has been found that the main pollution causing abandoned farmland was wastewater with high concentration of dissolved salts from corroded pipeline of the oil field. The contents of total salts from the polluted soil were 7.07 g·kg-1. Of them, Na+ and Cl- were 9.39 and 11.56 cmol· kg-1, respectively. The contents of them were 6.0, 7.8 and 18.1 times as much as that of unpolluted soil. The high contents of total salt. Na+ and Cl- caused compaction of the soil association with degradation and deterioration of soil ecological environment.
