人口迁移与森林变迁的关系研究——以四川通江县为例

A Study of the Relationship between Population Migration and Forest Vicissitude--A Case Study of Tongjiang County

通过以通江县(八家坪)为个案进行实地考察,我们可发现在不同历史时期,由于该地区人口迁移、人口数量的变化而对森林变迁所产生的重要影响。此外,从通江县的地名研究中也可以透视出人口迁移与森林变迁之间存在的紧密联系。研究表明,自明代到20世纪初,由于整个通江地区人口的增减,其森林面积也在随之发生改变,该地区各时期森林覆盖率的变化无不烙上人口迁移及人类生产生活的印记。

Based on the field investigation of Tongjiang County as a case study, the writers of this article find that in different historical periods, migration and the change of population in number had great influences on the vicissitude of forest. Additionally, the study of place names in Tongjiang also reveals the close relationship between the migration of population and the vicissitude of forest. In short, from Ming dynasty to the beginning of the 20 th century, the acreage of forest changed with the change of population in Tongjiang area.
