摘要
山东省平邑县是“中国金银花之乡”。为了查明平邑金银花主产区土壤中养分、重金属元素的含量与分布特征,评价土壤养分、土壤环境质量状况,圈定绿色食品产地分布区,通过1∶5万土壤地球化学测量、实验测试等,开展了平邑金银花主产区绿色种植适宜性评价工作。结果表明:研究区表层土壤大部分元素含量处于低背景,N、SOM、Cd、Hg明显偏低,富集系数<0.8;As、Cr、Pb略偏低,富集系数在0.8~0.9之间;仅Cu含量处于偏高水平,富集系数在1.1~1.3之间,元素分布主要受地质背景影响。土壤养分属于中等水平,相对适宜种植高品质金银花;整体环境质量良好,以无风险为主。Cu富集较明显,富集系数为1.30,自然源叠加人为源的可能性较大;其他重金属元素富集系数在0.57~0.95之间,来源主要是自然源。农业用地以绿色食品产地为主,面积435.22 km^(2),为金银花主产区发展绿色农业提供了地质基础。
Pingyi county in Shandong province is known as the"Hometown of Honeysuckle in China".In order to investigate the content and distribution characteristics of nutrients and heavy metal elements in the soil in main honeysuckle producing area in Pingyi county,evaluate soil nutrients and soil environmental quality,and delineate the distribution areas of green food production areas,through soil geochemical surveys with the scale of 1∶50000 and experimental testing,a suitability evaluation of green planting in main production area of Pingyi honeysuckle has been carried out.Most of the elements in the surface soil in the study area have low background levels,with N,SOM,Cd,and Hg being significantly lower.The enrichment factors are less than 0.8.As,Cr,and Pb are slightly lower,with enrichment factors ranging from 0.8 to 0.9.Only the content of Cu is at a higher level,with an enrichment factor ranging from 1.1 to 1.3.The soil nutrients in the study area are of medium level,which is relatively suitable for planting high quality honeysuckle.The overall environmental quality of the study area is good without risk.The enrichment of Cu in the study area is relatively obvious,with an enrichment factor of 1.30.There is a high possibility of natural sources overlapping with anthropogenic sources.The enrichment factors of other heavy metal elements range from 0.57 to 0.95.It is indicated that their sources are mainly natural.The agricultural land in the study area is mainly used for green food production,and the area is 435.22 km^(2).It will provide a geological foundation for the development of green agriculture in main honeysuckle production area.
