钾盐是生产钾肥的重要原料。全球钾盐资源高度集中,国际钾肥贸易的定价权一直牢牢掌握在西方国家手中。当前,中国农业正处于转型期,对于化肥的使用量和依赖程度大幅上升。然而中国钾盐资源严重不足,其储量只占世界总储量的2.36%,主要集中在青海察尔汗盐湖和新疆罗布泊盐湖。这两个矿区开采量已接近极限,再过度开发,将面临资源枯竭的危险。根据《中国钾盐工业》最新统计显示,2014年中国进口钾盐811.54万吨,其中氯化钾803.16万吨,硫酸钾5.49万吨,农用硝酸钾2.89
Potash is an important raw material for potash production. The global potash resources are highly concentrated. The pricing power of international potash trade has been firmly in the hands of western countries. At present, China’s agriculture is in a period of transition, and the amount and dependence on chemical fertilizers have risen sharply. However, there is a serious shortage of potash resources in China. Its reserves account for only 2.36% of the world total reserves, mainly in Qinghai Chaerhan Salt Lake and Lop Nur Salt Lake in Xinjiang. Both mining areas are near the limit of exploitation, and then over-exploitation will face the danger of resource depletion. According to the latest statistics of “China’s potash industry”, China imported 8,115,400 tons of potash in 2014, of which 8,031,600 tons of potassium chloride, 54,900 tons of potassium sulfate and 2.898 tons of agricultural potassium nitrate
