历史时期三川河湫水河流域的土地利用
发布时间：2019-03-04 14:21
【摘要】：本文探讨了近2000年来三川河、湫水河流域人口、耕地的发展史,初步结论是(1)从西汉到明中叶,农垦并非本区土壤侵蚀的主因,导致植被破坏和水土流失的主因是自然力与某些时期传统的过度放牧;(2)明弘治年间以后,本区人口逐步增加,开始垦种坡地;(3)清初施行“滋生人丁永不加赋”及“摊丁入亩”等鼓励政策,促进了人口和耕地的无限制增长;(4)清代到上世纪90年代的350年,由于人口飞跃增长,陡坡地大量开垦,是土壤侵蚀加速时期
[Abstract]:This paper discusses the development history of population and cultivated land in Sanchuan River and Qiushui River Basin in the past 2000 years. The preliminary conclusion is: (1) from the Western Han Dynasty to the middle of Ming Dynasty, agricultural reclamation is not the main cause of soil erosion in this area. The main causes of vegetation damage and soil erosion are natural forces and traditional overgrazing in some periods. (2) after the Hongzhi period of Ming Dynasty, the population of the district increased gradually and began to reclaim sloping land; (3) in the early Qing Dynasty, the encouraging policies such as "breeding people will never add taxes" and "spreading into mu" promoted the unrestricted growth of population and arable land; (4) in the 350 years from Qing Dynasty to 1990's, due to the rapid growth of population, a large amount of land was reclaimed on steep slopes, which was the accelerated period of soil erosion.
