中文摘要	辽宁省菱镁矿煅烧产生的粉尘对土壤污染越来越严重，但目前关于菱镁矿粉尘污染土壤的改良机理并不清楚，为此采用大石桥市菱镁矿粉尘重度污染土壤进行盆栽试验，研究了猪粪与磷石膏配合施用对菱镁矿粉尘荇染土壤化学性状的影响。结果表明．施用磷石膏、猪粪与磷石膏配合施用可降低土壤pH幅度为0．3-0．6，增加水溶性钙镁比值（Ca^2＋/Mg^2＋）幅度为1．57-3．02。单施猪粪、猪粪与磷石膏配合施用增加了土壤中速效氮、磷、钾的含量。单施猪粪对土壤pH和Ca^2＋/Mg^2＋影响不显著，单施磷石膏增加了土壤中速效磷含量．施用猪粪与磷石膏可以有效地改善菱镁矿粉尘污染废弃地的土壤化学性状，且以两者配合施用的效果最好。
英文摘要	The abandoned plantation fields which are polluted by dust from magnesite calcination expand widely in Liaoning province, north- east of China. But until now, the mechanism of the contaminated soil amendment is not clear. The pot experiments with heavy polluted soils by dust from magnesite calcination in Dashiqiao city were carried out to study the effects of swine manure, phosphogypsum, and mixture of both amendment treatments on the soil chemical properties. Applying phosphogypsum and mixture of swine manure with phosphogypsum could decrease the soil pH values, with the range of 0.3-0.6, and increase the ratio of Ca^2＋ to Mg^2＋ with the range of 1.57-3.02. Applying swine manure, the mixture of swine manure with phosphogypsum increased the contents of the soil bio-available N, P and K, but, the application of the swine manure had no significant effects on the soil pH and Ca^2＋/Mg^2＋ but increased the contents of the soil bio-available P. These results indicated that using swine manure, phosphogypsum, and the mixture of both amendments could effectively reclaim the deserted fields polluted by the dust from magnesite calcinations, among which the mixture of swine manure with phosphogypsum was the best.
