山东省平邑县九间棚村土壤地球化学调查评价OA

Jiujianpeng village in Pingyi county in Shandong province is located in the cnetral region of Yi-meng mountains.In order to identify the content and distribution characteristics of beneficial and harmful elements in the soil of the study area,delfine typical land resources,and analyze the suitability of planting typical agricultural product honeysuckle,by using soil sample collection and analysis,data statistics,and correlation analysis,geochemical survey and evaluation of land quality with the scale of 1∶10000 has been carried out.Comparing with the background values of the surface soil in Linyi city.The Na2O index is sig-nificantly lower,while I,Ge,B,F and CaO indexes are significantly higher.The enrichment characteris-tics of elements related to geological background or biological cycling processes in the soil in the study area have been reflected.The distribution of heavy metal elements in the study area is mainly influenced by geo-logical background and human factors.The overall quality of soil heavy metal environment is good.It will lay a good foundation for the development of green agriculture.The define land area for selenium enrich-ment is 36.7hm2,germanium enrichment is 131.0hm2,and zinc enrichment is 84.5hm2.It will guide the direction for the development and utilization of typical land resources in the study area.Through suitability analysis of honeysuckle,combining with the conditions of topography,soil type and soil fertility,it is re-garded htat the study area is suitable for planting high quality honeysuckle.It will provide geological data support for high quality development of local typical agriculture.
