摘　　要：Land reclamation is a process of ecosystem reconstruction, for which it is very important to keep co-adaptation between plants and the below ground habitat. In order to keep the co-adaptation among plant species, thickness of covering soil and medium of covering soil to establish a self-regulating ecosystem, the thickness of covering soil of land reclamation for plants in different living forms by synusia structure of plant below-ground habitat and medium of covering soil by ecological factors of plant below-ground habitat were studied. Synusia structure of plant below-ground habitat was recognized through investigation on structure and root of plant community, and ecological factors were determined through soil profile investigation. The thickness and medium of covering soil of land reclamation for the tree, the shrub and the herb were proposed.1研究方法1．1研究区概况研究区位于河南省巩义市大峪沟煤矿，属黄土丘陵地区，为较典型的半干旱气候类型。土地复垦的主要内容为塌陷区土地复垦和矸石山复垦。1．2调查方法该研究的重点放在不同生活型植物物种与地境层片的对应关系，以及各层片的水肥条件与植物长势的关联这两个问题上。地面以上开展植被调查，地面以下开展地境结构及地境内生态因子调查：
