中国石材生产一向是难于做出定量描述的。若根据最保守的估计,年开采量是6百万吨,而根据较宽松的分析数据,年开采量已经超过了2千5百万吨大关。考虑到各种制约条件所带来的困难,真实的情况可能更接近于前者,而不是后者。一些根据原材料和生产设备所做的分析结果表明,中国石材的年生产量约为8百万吨。 无论如何,一个不容否认的事实是,经过若干年的发展,中国已经在国际石材加工舞台上发挥了重要的
Chinese stone production has always been difficult to make quantitative descriptions. According to the most conservative estimate, the annual extraction volume is 6 million tons, and according to looser analysis data, the annual extraction volume has exceeded the 25 million tons mark. Taking into account the difficulties caused by various constraints, the real situation may be closer to the former than the latter. Some analysis results based on raw materials and production equipment show that the annual production of stone in China is about 8 million tons. In any case, an undeniable fact is that after several years of development, China has played an important role in the international stone processing arena.
