Abstract:

The soil environmental quality of arable land in China tends to deteriorate, especially the soil pollution is increasingly prominent. The area of polluted soil is  obviously expanding. The soil pollution mainly comes from sewage irrigation, sedimentation of atmospheric pollutant, disorderly stacking of solid waste, household garbage, and improper agricultural production process. The soil pollution of arable land possess the characteristics of concealment, hysteresis, accumulation, governance hardship, and trend to polyphyly and complexity. This paper reviewed the soil pollution status quo of arable land in China and the main  sources of pollution. The paper also analyzed the main characteristics of soil pollusion of arable land. Before ending, the paper put forward several issues should be paid more   attention during developing and implimenting policy measures for controlling soil pollution of arable land so as    to provide references for the improvement of soil environment of arable land in China.

摘要：

我国耕地土壤环境质量趋于恶化，尤其是土壤污染问题日益突出，受污染的土壤面积呈明显扩大之势。土壤污染主要来自于污水灌溉、大气污染物沉降、无序堆放的固体废弃物及生活垃圾和不合理的农业生产过程等。耕地土壤污染具有隐蔽性、滞后性、累积性、治理的艰难性，以及趋向多源性和复杂性等特点。综述了我国耕地土壤污染的现状和主要的污染物来源，并分析了耕地土壤污染的主要特点，最后提出了在制定防治耕地土壤污染政策措施过程中应注意的几个问题，以期为我国耕地土壤环境的改善提供参考。
