摘要
基于近十年的社会经济和资源环境数据,从农药和化肥、地膜、废水等方面探讨石河子垦区耕地土壤污染问题,发现农药、化肥、地膜的平均增长率远大于耕地平均增长率(仅为0.003),地膜覆盖面积平均为73%,废水实际达标率不足50%。文中提出评价模型,结果表明其耕地土壤污染中度偏轻,并分析了相关影响因素,最后作对策研究,以期为土壤污染治理提供相关参考。
Based on the data of social economy and resource environment in recent 10 years, the problem about soil pollution of Shihezi cultivated land was discussed in terms of pesticides and chemical fertilizer, mulching film, waste water etc. Average growth rates of pesticides, chemical fertilizer and mulching film were much more than that of cultivated land increase（ only 0.003 ）, and average cover area of mulching film was 73%, and quali fied rate of waste water discharged was less than a half. The result of the evaluation model structured by the re search showed a slightly moderate level, then influencing factors and treatments were analyzed in order to con tribute to soil oollution abatement of Shihezi cultivated land.
