利用PRA方法研究小尺度区域土地利用变化--以科尔沁沙地尧勒甸子村为例

土地利用变化研究可涉及多个时空尺度,目前正由全球性研究不断转向针对性的区域性研究。典型区域的小尺度研究是其研究的一个重要方面。参与性农村评估(PRA)是一种通过与研究地区居民进行非正式访谈来对地方的实际情况有所了解的方法。文章借助PRA结合实地测量,以科尔沁沙地东南部尧勒甸子村为例对小尺度区域的土地利用变化进行初步研究。绘制一系列尧勒甸子村建国以来各个时代的土地利用图,重建和恢复了其50年来的土地利用过程,并运用GIS对其土地利用变化进行了研究。

Apply the Participatory Rural Appraisal Method to the Research of Land Use Change in Local Scale--A Case Study of Village Yaoledianzi of Korqin Sands

The research of land use change deals with different spatio-temporal scales. It is towards the regional research. The research of local scale of typical region is one of the important aspects in land use change. The Participatory Rural Appraisal (PRA) is a method by which the researcher acquired the basic situations of the research region by using informal interview with the local residents. PRA is, along with field measure, applied to study the land use change in village scale, taking village Yaoledianzi of Korqin Sands as example. The research protracted a series of land use maps of different era, reconstructed the land use history of the past 50 years and analyzed land use change by GIS.
