中文摘要	石漠化是我国西南地区广泛分布的一种生态--地质灾害.石漠化地区的提取和等级的划分是石漠化研究的首要前提.裸岩率作为石漠化等级划分的一个重要指标,对其科学快速的运算,是石漠化等级划分和石漠化地区提取的基础.提出了一种基于多光谱遥感影像的裸岩率的计算方法,并选取贵州省普定县后寨河流域1987年的TM影像进行了实验.首先,对影像进行预处理获得影像对象,再通过波段运算提取后寨河流域的归一化植被指数NDVI和裸土指数BI,分别用来计算植被覆盖度和土壤裸露率,最后通过图层算术运算获得实验区的裸岩率.结果表明这种裸岩率的提取方法具有可行性
英文摘要	Karst rocky desertification is one of the most serious geo-ecological disaster in Southwestern China. The extraction of rocky desertification regions and grade division of rocky desertification are the most important premises to do rocky desertification research. The percentage of bare rock is an important index to do rocky desertification grade division. Using scientific and fast methods to calculate the percentage of bare rock is the basis for the extraction of rocky desertification regions and grade division of rocky desertification. We proposed a multi-spectrum remote sensing image-based method to calculate the percentage of bare rock and the TM image at 1987 of Houzhai stream in Puding County, Guizhou Province was chose as experiment data. Firstly, the image was processed to attain the image object. Then, extract the Normalized Difference Vegetation Index(NDVI) and Bare Soil Index(BI) from the image by band calculation. NDVI and BI were used to calculate vegetation coverage and soil bareness percentage, respectively. Finally, the percentage of bare rock could be calculated by making use of layers arithmetic operation. The experiment result shows that the method proposed in this paper has feasibility
