摘要
钾是植物生长的第三要素,它在植物的扩张、新陈代谢和生长中起着至关重要的作用。钾肥是粮食中的“粮食”,中国有56%的耕地处于缺钾状态,因此其稳定性供应事关粮食安全和农业安全。中国是世界第一钾盐消费大国,但是中国钾肥资源严重不足,我国70%钾肥靠进口。由于钾矿资源具有不可再生性和空间分布不均衡的特点,在日益紧张的国际形势下,合理开发利用我国的钾矿资源具有非常重要的意义。本文先对全球钾盐储量及产能现状进行了简单介绍。再针对我国钾盐开发利用过程中存在的钾盐储采比低、产品种类单一、盐田蒸发过程中钾资源损失严重等问题,综述了资源配置优化和循环经济在钾盐矿产资源开发过程中的相关研究,并对我国钾资源的高效利用和可持续发展提出了建议,为钾盐资源高质量发展提供路径。
Potassium is the third element of plant growth,which plays a vital role in plant expansion,metabolism and growth.With 56%of China’s arable land lacking potassium,the stable supply of potash is a matter of food security and agricultural security.China is the world’s largest consumer of potash,but its potash resources are seriously insufficient,and 50%of potash is imported.Due to the characteristics of non-renewable nature and unbalanced spatial distribution of potassium resources,it is of great significance to develop potassium resources reasonably under the increasing tense international situation.The present situation of global potash reserves and production status distribution are first introduced in this paper.There are some problems in the development and utilization of potassium salt in China,such as low storage-production ratio of potash,single product variety,and serious loss of potassium resources in the evaporation process of salt fields.This article reviews the related research on resource optimization and circular economy in the development of mineral resources at home and abroad,and puts forward suggestions on the efficient utilization and sustainable development of potassium resources in China,which provides a path for the high-quality development of potassium resources.
