摘要
喀斯特石漠化是中国西南地区面临的重大生态顽疾,运用遥感技术进行石漠化信息提取是大范围监测不可或缺的手段。本文在分析相关科学文献的基础上,首先简述了喀斯特石漠化的分布概况及分级评价指标,然后对石漠化遥感信息提取方法进行了总结及对比分析,指出现有信息提取方法存在的不足,最后初步预测了未来石漠化遥感监测的发展趋势。
Karst rocky desertification is the major disaster in southwest China, while remote sensing information extraction is indispen- sable to monitor this disaster. Based on the analysis of relevant scientific literature, this paper firstly introduced the distribution and grading evaluation index of rocky desertification. Then extraction methods of rocky desertification were compared and summarized. Fi- nally, through analyzing the problems of the existing extraction methods, the developing trend was produced.
