摘要
以屈家岭管理区为研究区,测定该区土壤样品中30项指标值,查明土壤养分丰缺、环境质量、健康元素状况及酸碱程度,划分土壤质量地球化学综合等级。结果表明,研究区土壤养分地球化学综合等级以中等及以上为主,较缺乏次之,其中中等及以上等级面积占研究区的63.95%;土壤环境地球化学综合等级以清洁为主,面积占比98.90%;土壤质量地球化学综合等级以良好—优质为主,中等次之,良好—优质和中等等级面积分别占比63.54%、34.41%。发现富Ge土壤区189.60 km^(2),为发展富锗特色农产品提供了地质依据。以土壤质量地球化学等级为基础,提出调整永久基本农田划定和治理重金属污染的建议。
Taking Qujialing Management Area as the research area,30 index values of soil samples in the area were determined to find out the soil nutrient abundance and deficiency,environmental quality,health element status and soil acid-base degree,and to divide the comprehensive geochemical grade of soil quality.The results showed that the comprehensive grades of soil nutrient elements in the study area were mainly medium and high,followed by the lack of soil nutrient elements.The area of medium grade and above accounted for 63.95%of the study area.The comprehensive grade of soil environmental geochemistry is mainly clean,accounting for 98.90%.The geochemical comprehensive grade of soil quality is mainly good high quality,followed by medium.The areas of good high quality and medium grade account for 63.54%and 34.41%respectively.It is found that the Ge rich soil area is 189.6 km^(2),which provides a geological basis for the development of Ge rich agricultural products.Based on the geochemical grade of soil quality,some suggestions are put forward to adjust the delimitation of permanent basic farmland and control heavy metal pollution.
