摘　　要：提出了根据植物群落地下生境的层片结构,确定不同生活型植物土地复垦的覆土厚度,根据植物地境内生态因子特征确定土地复垦的覆土基质;如此进行复垦,可保证植物物种、覆土厚度、覆土土质三者之间的协调适应,建立一个能够自我调节的生态系统。并通过研究提出了土地复垦时,乔木、灌木、草本植物的覆土厚度和覆土基质。In this experiment, it was proposed that the covering soil thickness on land reclamation with different life form plant was determined according to the underground habitat synusia structure and the covering soil substrate on land reclamation was determined according to ecological factors in underground habitat. The reclamation was carried out according to this method, plant species, covering soil thickness and covering soil were coordinatively adapted to construct a ecosystem which could conduct self-regulation. Moreover, it was also proposed the covering soil thickness and covering soil substrate of trees, bushes , herb plants, when the land was conducted reclamation.
