摘要
坡地村落是指分布在山地、丘陵坡面上的村庄,广泛分布于我国的山区聚落中,是我国乡村聚落的重要类型。西部山区是坡地村落分布的主要地区,"十二五"期间随着主体功能区规划的实施,不仅会影响坡地村落的空间重组和人口迁移,也会影响到坡地村落的农户生计和山区区域发展问题。论文以坡地村落空间演进和农户流动为切入口,借助黄土高原和西南山地典型地区的分析,运用GIS和大比例尺地形图分析了坡地村落空间集中和分散的基本特征。通过实地考察和问卷分析,剖析了村落空间演进和人口流动过程中农户耕地资产、收入、基本生活方式等主要生计的改变。结论认为,以减缓生态环境压力、调和人地矛盾和扭转经济贫困为最初目标的人口迁移,总体来说,有着显著的正效应,主要表现在退耕使生态用地比重得到提高、劳动力收入渠道拓宽、基础设施和社会公共服务得到显著改善等方面。
Slopes villages refer to villages locating on the slopes of mountains and hills, which are distributed extensively in mountain settlements and constitute an important type of the village set- tlements in China. The western mountainous areas, which are the main slope village distributed areas, have faced the resources and ecology bottleneck because the long time population growth pressure have made them in recent years the main areas of population movement, and frequent village migrations. With "the Main Function of the National Planning" implemented in the "Twelfth Five-Year Plan on National Economic and Social Development" period, the above regions will be faced the new opportunities and challenges. The spatial reorganization and the population migra- tion in the slope village distributed mountainous areas will be also influenced. And finally the ru- ral household livelihood and sustainable development in mountainous area will be affected. These two problems have exactly long puzzled the western rural development. Accessing the villages space evolution and the peasant households, using the multi-time re- mote sensing images (TM, ETM, and Alos at 2. 5 m resolution) and topographic maps of different scales (1 : 50000, 1 : 100000 and 1 : 250000) , the disperse and concentrate characteristics of the two spatial evolutions types of the slope villages were analyzed by using the GIS spatial analy- sis tools. The concentration is the slope village households' movements from the slope lands down to the smooth lands under the environmental pressure and driven by most of the benefits. One con- centration type is its position located on some bigger river valley plains and some main roads are caused by the spatial difference of the slope village' site conditions. Another nearby bigger mar- kets and the advantageous traffic accesses are caused due to infrastructure reconstruction and mar- ket mechanism establishment in western mountainous areas. The dispersion is the slope village households'movem
