摘要
喀斯特石漠化是发生在亚热带岩溶地貌中的土地退化过程,其显著特征为土壤严重侵蚀、基岩裸露、植被退化、土地生产力下降。石漠化既制约当地的经济发展,又可能引起小环境气候的恶化,同时也破坏生物多样性,危及生态环境自然景观。因此,研究石漠化,分析其成因和分布特征对喀斯特地区的防灾减灾以及可持续发展具有十分重大的意义。EOS-MODIS数据所固有的优点(获取便捷、覆盖范围广、成像周期短),使其成为理想的大范围石漠化研究的潜在遥感数据源。
Karst rocky desertification is occurring in sub-tropical karst landforms in the process of land degradation, its significant features for the serious soil erosion, bare rock and vegetation degradation,declining land productivity. Rocky desertification is restricted to local economic development, it was likely to cause the deterioration of the climate niche, as well as damage to biodiversity, endangering the ecological environment of the natural landscape. As a result, rocky desertification research, analysis of its causes and distribution of the Karst region,as well as disaster prevention and reduction of sustainable development is of great significance. EOS MODIS data inherent advantages （easy access,wide coverage, imaging short ） , making it ideal for large-scale study of rock-desertification of the potential of remote sensing data sources.
