土壤有毒物质背景值,是当前评价土壤质量变化趋势的重要标准之一,也是计算土壤环境容量,预测、预控土壤质量变化趋势的重要依据。为评价东营地区土壤质量状况,已于1984年11月对该地区土壤有毒物质背景值做了调查研究。本文刍议土壤质地(仅指物理性粘粒含量,下同)和有机质含量对土壤有毒物质背景值的影响及其调查研究方法。
The background value of soil toxic substances is one of the most important criteria for evaluating the trend of soil quality. It is also an important basis for calculating the soil environmental capacity, forecasting and predicting the trend of soil quality change. In order to evaluate the soil quality status of Dongying area, the background value of soil toxicant in this area was investigated in November 1984. This article discusses the soil texture (only refers to the physical clay content, the same below) and the content of organic matter on the soil toxic substances background value of the investigation and research methods.
