摘要
土地复垦可以恢复矿区土地使用功能,保护耕地,恢复生态环境。土地复垦工艺有覆土和无覆土两种,复垦技术则包含生物复垦和工程复垦两个方面。目前我国矿山土地复垦率不足10%,复垦技术以单一恢复植被为主,基本未考虑恢复自然生态。应从加强宣传,综合各相关学科加强研究,建立科学、有效、全面的复垦技术等7个方面入手,大力加强我国的矿山土地复垦工作。
Reclaim of land can renew the soil function of the mine,protect the cultivated land and renew ecological environment.There are two kinds of reclaiming technologies,Those are covering-soil technology and uncovering-soil technology.Reclaiming skill contain creature reclaiming and engineering reclaiming.At the present,the reclaim rate in mine is less than 10 percent in China.The skill of reclaiming is mainly renew the forest,and we don't think of renewing natural ecology.So we should enhance propagation and synthesize the study of related disciplines to build scientific,effective and comprehensive technology.
