新疆若羌县土壤质量地球化学评价
|
摘要
参照《(DZ/T 0295—2016)土地质量地球化学评价规范》测定了土壤样品中17项元素指标,查明了土壤环境质量和土壤养分丰缺状况,综合评价得到土壤质量综合等级.结果表明,研究区农用地环境综合质量状况较好,地球化学等级以中等为主,面积占85.9%;土壤养分综合等级以稍缺为主,有机质、N、Fe和Zn较缺乏,Mo较丰富.土壤环境质量总体较好,轻度-重度污染面积不足8%,土壤污染主要受As、Cr和Cd的影响.同时,本次评价发现了占研究区面积5.3%的富硒土地资源,为当地发展富硒特色农产品提供了基础依据.
According to the "Specification of Land Quality Geochemical Evaluation(DZ/T 0295—2016)", 17 elements in the soil samples were determined, soil environmental quality and soil nutrient abundance status were identified, and comprehensive evaluation of soil quality was obtained. The results showed that the quality of the agricultural land in Ruoqiang County was in good condition, with medium geochemical grade accounting for 85.9%. The comprehensive level of soil nutrients was mainly lacking, among which organic matter, N, Fe and Zn were lacking, and Mo was rich. The soil environment quality was generally good, and the area of mild to severe pollution was less than 8%. Soil pollution was mainly affected by As, Cr and Cd. Meanwhile, this evaluation found that the selenium-rich land resources accounted for 5.3% of the study area, providing a basis for the local development of Se-rich agricultural products.
