| 摘 要： | 在青海省民和县新民—李二堡地区进行土壤地球化学调查的基础上，通过对574个土壤样品测试分析，研究其中有机质、氮(N)、磷(P)、钾(K)、硫(S)、水溶性钙(Ca)和镁(Mg)等养分指标和pH值等。结果显示，研究区主要属于碱性—强碱性土质，K富集，P中等偏富，N较贫乏，个别地区S超标。综合评价研究区，土壤养分丰富的一级和较丰富的二级土壤面积占3199%，中等级别占438%，较贫乏占2407%，贫乏地区占015%。研究结果为该区土壤改良和高效利用提供了参考。

| Abstract: | Based on the soil geochemical survey in Xinmin Lierbao area, we collected 574 soil samples for geochemical analysis and testing. The pH values and nutrient indicators,such as organic matter, nitrogen (N), phosphorus (P), potassium (K), sulfur (S),water soluble calcium (Ca) and magnesium (Mg), were discussed. The study area mainly belongs to alkaline strong alkaline, rich K, medium rich P, poor N soil, S exceeding in some areas. In the comprehensively researched evaluation, there are first and second rich levels accounting for 3199%, the middle rich levels accounting for 438%, the low middle rich levels accounting for 2407% and the poor levels accounting for 015% in the study area. The results provide reference for soil improvement and high efficiency in the study area. |
