摘要
调查了宁夏青铜峡贺兰山东麓冲积、洪积的干旱荒漠草原约２００ｋｍ２的水氟、表层土壤水溶氟、牧草氟、大气含氟量和在当地放牧的牧羊业受氟害的情况。结果表明．这里的水氟、土壤水溶氟、牧草含氟量等均比氟安全区偏高，属自然高氟地区。自然高氟地区对牧羊业的危害－主要使母羊寿命比氟安全区约减少一半而造成经济损失，经估算每平方千米约损失３８０元。
The water flourine, topsoil water-soluble flourine,flourine in herbage, atmosphere flourine content and flourine damage to animal husbandary were investigated in 200km2 Qintongxia arid and desert grassland of eastern Helanshan Mountain, Ningxia Province. The result shows that the water flourine, soil water - soluble flourine and flourine in herbage are higher than those of safe area. Qintongxia area is that of naturally high flourine. The damage to andesal husbandry is that the life -span of female sheep is about the half of that in safe area. The economic loss is estimated at about 380yuan/km2.
