- 兰坪思茅盆地水化学特征及找钾指标探讨 摘要 - 本文通过对云南省兰坪思茅盆地水化学特征的研究，探讨了该盆地 pH 地下水中的主要离子含量、值、总硬度、电导率等方面的特征，并从 找钾指标出发分析了该地区的钾资源潜力评价。结果表明，该盆地地下 Na+Mg2+Ca2+Cl- 水中主要含有、、、等离子，并呈现轻微的咸化趋 pH7.19 势；值平均为，表明该地区地下水呈中性或微碱性；总硬度平均 198.7mg/L401.5μS/cm 为，电导率平均为，这也表明地下水较硬、较 -5.83mg/L 咸。钾离子在兰坪思茅盆地地下水中的平均浓度为，低于找钾 7mg/L 指标中的，说明该地区钾资源潜力较低。因此，应该在实际开采 钾资源时认真评价该地区的钾资源开发潜力。 - 关键词：兰坪思茅盆地；地下水；水化学特征；找钾指标；钾资源 潜力评价 Abstract This paper investigates the hydrochemical characteristics of the Lanping-Simao Basin in Yunnan Province, and analyzes the main ion content, pH value, total hardness, conductivity and other aspects of groundwater in the basin. From the perspective of potassium resource potential evaluation, this paper studies the potassium ion concentration in groundwater, and explores the resource potential of potassium in this region. The results show that the main ions in the groundwater of this basin are Na+, Mg2+, Ca2+, Cl-, and there is aslight trend of salinization in the groundwater. The average pH value is 7.19, indicating that the groundwater in this area is neutral or slightly alkaline. The average total hardness is 198.7mg/L, and the average conductivity is 401.5μS/cm, indicating that the groundwater is relatively hard and salty. The average potassium ion concentration in the groundwater of the Lanping-Simao Basin is 5.83mg/L, which is lower than the finding potassium index of 7mg/L, indicating that the potential of potassium resources in this region is relatively low. Therefore, it is necessary to evaluate the potential of potassium resource development in this area carefully. Keywords: Lanping-Simao Basin; groundwater; hydrochemical
