安徽省砀山县葛集镇土地质量地球化学评价

Geochemical Evaluation of Land Quality in Geji Town in Dangshan County in Anhui Province

摘要:

为助力安徽省砀山县脱贫攻坚，开展了砀山县1∶5万土地质量地球化学调查工作。本文以葛集镇为研究对象，按6.4个点/km2的平均密度采集表层土壤样品，系统分析了该镇土壤样品中N、P、Cd、Hg、As、Zn等12项元素的含量或指标特征，综合评价了土壤养分、土壤环境、土壤质量以及特色土地资源。结果表明，葛集镇土壤质量整体较好，良好以上土壤面积为78.81km2，占总评价面积的94.12%，无差等、劣等土壤；优势特色富锌土壤面积为37.47km2，占总评价面积的54.07%。本次研究工作可为生态农业经济高质量发展提供科学地质数据支撑。

Abstract:

In order to assist the poverty alleviation campaign in Dangshan county in Anhui province, a geochemical survey of land quality with the scale of 1∶50000 has been carried out. In this paper, taking Geji town as the research object, by collecting surface soil samples at an average density of 6.4 points/km2, the content or indicator characteristics of 12 elements, such as N, P, Cd, Hg, As, Zn in the soil samples of the town have been analyzed systematically. A comprehensive evaluation of soil nutrients, soil environment, soil quality, and characteristic land resources have been conducted. It is showed that the overall soil quality in Geji town is good, with an area of 78.81km2 of good or above soil, accounting for 94.12% of the total assessed area, and no poor or inferior soil. The advantageous characteristic zinc rich soil area is 37.47km2, accounting for 54.07% of the total evaluated area. This research work can provide scientific geological data support for high quality development of ecological agriculture economy and assist in rural revitalization.
