摘　　要：喀斯特脆弱区的生态重建是我国当前治理土地退化的重要课题 ,西南喀斯特地区在实践中已经摸索出一系列生态重建的模式。运用地理学的尺度视角 ,考察不同尺度下生态重建的目标及重建手段存在的差异 ,选取不同尺度下的典型生态重建模式 ,重点分析模式的尺度特征及其经济、社会和生态效益 ,提出选择与探索生态重建模式时应重视重建的尺度特征 ,整合不同尺度下的生态重建 ,以推动区域可持续发展。Ecological rehabilitation of the degraded land in karst fragile region is one of the most important issues for China at present. People in karst areas of southwest China have already established a series of ecological rehabilitation models in practice. The authors take the scale perspective of geography to consider the differences of aims and means of ecological rehabilitation models at various scales, and choose typical models at different scales, analyze scale characteristics of these models and their economic, social and ecological benefits. It is concluded that special attention should be paid to scale characteristics of the models when evaluating and choosing them and the ecological rehabilitation at different scales should be combined in order to promote the sustainable development of the region.
