沈抚灌区土壤生态恢复途径初步研究

Primary Study on the Approach of Farmland Ecological Resume in Shen-Fu Irrigation Area

沈抚灌区是我国最大的石油类污灌区之一 ,已有长达 40年的污灌历史。灌区土壤中石油类有机污染物积累严重 ,特别是芳烃类污染物所占比例逐年增高 ,已给区域人群健康带来很大的潜在威胁 ,农田土壤的生态恢复迫在眉睫。本文全面分析了沈抚灌区土壤的污染特点 ,进行了土壤生物修复的初步研究 ,阐述了土壤生物修复方法的选用和开发方向 。

Shen-Fu irrigation area,being one of the biggest irrigation areas with wastewater containing petroleum pollutants in China,has existed for more than 40 years.The pertoleum pollutants have been accumulated seriously in irrigated soil,especially the proportion of aromatic hydrocarbon pollutants has been increasing year after year.The soil contamination has brought serious effects on the people's health in this area,so it's very urgent to resume farmland ecology.The characteristics of soil contamination is Shen-Fu irrigation area were analysed completely,and primary test of soil bioremediation was studied,and the selection and development of soil bioremediation method were expatiated,at last the approach of farmland ecological resume in Shen-Fu irrigation area was discussed in this paper.
