• 摘要：在沈阳张士灌区采用综合方法治理镉污染农田。在中度和轻度污染土壤种植水稻,控制灌溉水质（Cd²+<2PPb,PH>7,Cl-<100ppm）或以清水灌溉,在重污染区,采用农业生态工程改良方法如农业改良（繁育水稻、玉米良种）,繁育绿化苗木和草皮、种植甜高梁提取酒精。结果表明,农业生态工程方法是合理利用和改良严重镉污染农田的良好途径。

• Abstract：The soils in Zhangshi Irrigation Area were polluted with cadmium due to continuous irrigation with industrial wastewater. A number of measures have been taken in an attempt to reclaim the farmland. For the soils slightly polluted with cadmium, rice growing with fresh water irrigation was suggested. In the case of heavily contaminated soils, an agro-ecological engineering approach was recommended.
