摘要在归集全国富硒土地成因类型及元素特征基础上,以干旱咸水湖沉积型富硒土地划定为示范,依据天然富硒土地划定与标识要求,评价、划定青海省平安区洪水泉乡土壤硒含量分级、环境质量和肥力质量。结果表明,洪水泉乡土壤呈碱性,属高有效硒的背景;土壤Se处于(0.037~6.544)×10^-6之间,均值为0.352×10^-6;土壤中Cd、Hg、Pb和Cr含量均未超过农用地土壤污染风险筛选值,土壤As在局部形成风险地块;土壤呈有效磷、速效钾丰富,氮和有机质中等的肥力水平。据此,划定研究区天然绿色富硒土地43 591亩,其中含可直接利用耕地13 513亩,潜在可利用林草地30 078亩。结合当地实际情况,提出在研究区发展农牧融合产业,形成“高硒宜粮、中硒宜牧”的产业布局的建议。本次研究对进一步挖掘青海省富硒土地资源,科学规划富硒产业,凸显区位优势,高效转化资源价值具有重要的参考意义。

Abstract：

Based on the summary of the genetic types and elemental characteristics of national selenium (Se)-rich land, this study explored the arid saline lacustrine sedimentary type Se-rich land. According to the requirements for the delimitation and identification of natural Se-rich land, this study assessed and delimited the Se content, environmental quality, and fertility of soils in Hongshuiquan Township, Ping'an District, Haidong City, Qinghai Province. The results indicate that the soils in the Hongshuiquan area are alkaline, exhibiting a high background level of available Se. Specifically, the content of soil Se ranged from 0.037 mg/kg to 6.544 mg/kg, with an average of 0.352 mg/kg. The contents of Cd, Hg, Pb, and Cr in the soils did not exceed their contamination risk screening values for agricultural land. Additionally, soil As shows potential risk in local plots. In terms of fertility status, the soils exhibit abundant available phosphorus and potassium, and moderate nitrogen and organic matter. Based on the above results and the designated values for Se-rich land in the alkaline soil area, while excluding soil contamination risk zones and considering the continuity, scale, and development and utilization of plots, this study delimited 43 591 mu (1 mu=0.066 7 hectares) of natural green Se-rich land in the Hongshuiquan area, including 13 513 mu for direct agricultural use, and 30 078 mu for potentially utilizable forest land and grassland. Considering local conditions, this study suggests the development of the integrated agriculture and animal husbandry industry in the Hongshuiquan area, centering on the delimited zones and extending to the peripheries with moderate Se content. Planting grain crops and green forage grass in the delimited zones, surrounded by free-range grazing, forming an industrial layout of land with high Se content for grain crops and land with moderate Se content for grazing. Overall, this study holds critical reference significance for further exploring Se-rich land resources in Qinghai Province, scientifically planning the selenium industry, highlighting location advantages, and efficiently transforming resource value.

Key words： arid saline lacustrine sedimentary type natural selenium (Se)-rich land Hongshuiquan area alkaline soil
