我国土壤环境质量监测技术路线研究

土壤环境质量监测技术路线根据"十二五"主要任务目标,设计了土壤环境监测国家、省、地(市)三级网络构架和以县级采样、地(市)级分析、省级质控、国家发布的网络运行模式,明确了每年监测一类重点区、5年完成一个监测周期的全国总报告,确立了以基本农田、蔬菜和果树基地、饮用水源地、重污染企业周边、规模化养殖场周边等为重点区域的约2.5万个国控采样点;对土壤重金属和有机污染物的分析测试与评价方法进行了优化筛选,制定了质控措施,对深入开展土壤环境质量例行监测具有重要意义。

The Research of Technique Route for National Soil Environment Monitoring

Based on the goal of soil environmental quality monitoring during Twelfth-Five-Year period, three-grade network including national, provincial and city of soil monitoring and operation mode of county-levelsampling,city-level analysis,provincial-levelquality controland national-levelpublication were both designed. About 25 thousand state-controlled sampling sites from key monitoring areas such as, basic farmland, vegetable and fruit base, drinking water sources, surrounding area of heavily polluting enterprises and large-scale farms were selected. The paper also suggested to annually monitory one kind of key monitoring area and to compose the reports of national soil environmental quality at a five year monitoring cycle. Furthermore, the optimized methods of analysis, evaluation and quality evaluationof heavy metals, organic pollutants were also described. It is important to deeply carry out soil environmental routine monitoring in future.
