亚高山古梯田是我国南方特殊的土地利用方式,主要研究了亚高山梯田从旱作到稻作形成过程及维护中自然与人相互作用,以及古梯田的水土保持机理。研究结果表明:亚高山古梯田形成于人地矛盾日益尖锐的10世纪左右,在满足粮食生产的同时,产生了保护自然环境、维系水土的生态效益,为我国大规模开展坡耕地水土流失综合治理工程建设提供了极为重要的借鉴。 The subalpine ancient terraces are the special land use patterns in southern China. They mainly study the natural and human interactions in the formation and maintenance of sub-alpine terraced fields from dry cultivation to rice cultivation, and the soil and water conservation mechanisms of ancient terraces. The results show that the subalpine ancient terraces were formed in the increasingly sharp 10th century when the contradiction between human and land was sharply increased. While satisfying the grain production, the ecological benefits of protecting the natural environment and maintaining the soil and water were produced. Project construction provides an extremely important reference.
