农用地土壤污染调查与监测评价系统研究

Study on the Agricultural Land Soil Pollution Investigation and Monitoring Evaluation System

本文以河北省三河市南部地区为试点,系统地介绍了样点布设、样品采集、制备、保存、检测的整套流程。通过多期采集的土壤样品、农产品样品、灌溉水样品的检测分析结果,建立了三河市土壤污染监测采样数据库。采用不同分析评价方法,开展土壤重金属污染评价以及监测预警分析,评价和分析结果为三河市农用地土壤环境质量分类管理、科学规划,提供了重要的工作支撑。

Taking the southern area of Sanhe City,Hebei Province as a pilot,this paper systematically introduces the whole process of sample point layout,sample collection,preparation,preservation and detection.Through the detection and analysis results of soil samples,agricultural products samples and irrigation water samples collected in multiple periods,the soil pollution monitoring and sampling database of Sanhe City was established.Different analysis and evaluation methods were used to carry out soil heavy metal pollution evaluation and monitoring and early warning analysis.The evaluation and analysis results provided important work support for the classification management and scientific planning of soil environmental quality of agricultural land in Sanhe City.
