中文摘要	探讨石漠化时空分布特征,有助于揭示石漠化发展过程及其规律.论文应用1990年、2000年和2006年TM遥感图像获得桂西北三个时段共16年的石漠化强度空间数据,在GIS软件中对土地石漠化类型数据进行编码和重组分析,得出桂西北土地石漠化在不同时间内的空间分布特征.结果表明,桂西北石漠化有加速发展态势,已石漠化地区的生态变化波动明显,石漠化治理成效不理想,空间格局分散.喀斯特生态退化和恢复过程具有明显不对称性.
英文摘要	It is helpful for understanding the process and rule of rocky desertification development to study the spatial-temporal distribution characteristics of rocky desertification. This study dealt with the spatial patterns in different periods in the region studied based on the information about rocky desertification distribution developed from TM remote sensing images in 1990, 2000 and 2006 in Northwest Guangxi Province, and the encoding and recombined analysis of rocky desertification types using the GIS technology. The study showed that the development tendency of rocky desertification in the region is accelerating, the ecological change is unstable obviously in the rocky desertification-stricken areas. At the present time, the effect of rocky desertification control is unfavorable, and the control areas are of dispersive distribution. The results also showed that the processes of ecological degradation and ecological recovery are unsymmetrical.
