坪坦河流域传统侗寨土地利用模式分析

Analysis of Land Use Pattern of Traditional Dong Stockade in Pingtan River Basin

土地利用模式研究旨在描述与解释土地利用复杂的空间分布。在实地调查的基础上,对坪坦河流域传统侗寨土地利用模式以及模式的形成机制进行了分析。结果表明,坪坦河流域传统侗寨土地利用主要以林地与耕地为主的类型模式,自然区模式则为典型的垂直分布,在水平方向上则出现以公共建筑用地为中心的向心型社会经济模式。坪坦河流域的自然条件为这些模式的形成提供初始的可能,然而模式最终形成却是该流域历史、侗族的世界观与信仰、生产方式等人文因素所决定。

The study of land use pattern is aimed at describing and explaining the characteristics of spatial distribution of land use. Based on field investigations,we here study the land use pattern and its formation mechanism in the basin of Pingtan river in the traditional Dong stockade. The result shows that： 1） the land use type in the study area is predominated by woodland and cultivated land,and 2） natural region of model display a characteristic vertical distribution feature, whereas social- economic model is horizontally centered around public buildings. Although the natural resources in the Pingtan river basin provide the bases for these models to develop,these models are determined collectively by humanistic factors,such as history,world outlook and belief,and production mode of Dong minority.
