我国迅猛的经济建设带动建设市场快速发展,工程用砂的需求量越来越大,天然砂的生成量已远不能满足日益增长的需求,而过量的开采更会影响并危及沿江沿河地区的稳定,故亟需开发利用人工砂资源。上海作为科学技术比较先进,而天然砂资源贫乏的城市,推广应用人工砂更有意义。
The rapid economic development in our country has led to the rapid development of the construction market. The demand for engineering sand is increasing. The production of natural sand is far behind the growing demand. Excess mining will affect and endanger the development of the sand along the river Stable, it is urgent need to develop and utilize artificial sand resources. As a city where science and technology are more advanced while natural sand resources are scarce, it is more meaningful to promote the use of artificial sand.
