| 摘 要： | 利用GPS定位选取河北省安平县京安猪场废水连续灌溉8 a的污灌区的36个样点,采用模糊综合评价模型对规模化猪场废水长期灌溉农田土壤重金属(Zn、Cu、Pb、Cr和As)污染状况进行了评价.结果表明,研究区36个采样点的土壤环境质量级别绝大部分为Ⅰ级(清洁),土壤未受到严重污染,但个别采样点土壤环境质量级别达到Ⅲ级(轻污染),呈现污染趋势,说明长期灌溉猪场废水,存在一定的土壤重金属污染风险. |
| 关 键 词： | 猪场废水 土壤 重金属污染 模糊综合评价模型 |

| Abstract: | With the rapid development of scale swine-farms in China, the swine waste which is brought by intensive hoggery is disposed in farmland soils around swine farm region.Due to plentiful heavy metals in swine wastewater, heavy metals can be accumulated in soils if longterm and large quantity swine wastewater is applied.The assessment of heavy metal pollution is an important issue in the research of heavy metal pollution in soil.According to the graduated feature and fuzzy feature in the degree of soil heavy me... |
| Keywords: | swine wastewater soil heavy metal pollution fuzzy comprehensive assessments model |
