中文摘要	以塔里木河下游为靶区,根据地面调查和不同分辨率的多源遥感数据,逐级建立荒漠植被覆盖度遥感估测模型,并对不同模型、不同估测方法的估测精度进行比较.结果表明:随着遥感数据空间分辨率的提高,植被覆盖度遥感估测模型精度增加;基于高分辨率、中高分辨率及中低分辨率遥感数据建立的植被覆盖度模型的估测精度分别为89.5%、87.0%和84.6%;遥感模型法的估测精度高于植被指数法。不同分辨率遥感数据估测荒漠植被覆盖度的精度变化规律,实现了荒漠植被覆盖度估测的高、中、低分辨率遥感数据参数及尺度的定量转换,可为研究区生态恢复遥感综合监测方案的制定和实施提供直接依据。
英文摘要	Taking the lower reaches of Tarim River in Xinjiang of Northwest China as study area and based on the ground investigation and the multi-source remote sensing data of different resolutions, the estimation models for desert vegetation coverage were built, with the precisions of different estimation methods and models compared. The results showed that with the increasing spatial resolution of remote sensing data, the precisions of the estimation models increased. The estimation precision of the models based on the high, middle-high, and middle-low resolution remote sensing data was 89.5%, 87.0%, and 84.56%, respectively, and the precisions of the remote sensing models were higher than that of vegetation index method. This study revealed the change patterns of the estimation precision of desert vegetation coverage based on different spatial resolution remote sensing data, and realized the quantitative conversion of the parameters and scales among the high, middle, and low spatial resolution remote sensing data of desert vegetation coverage, which would provide direct evidence for establishing and implementing comprehensive remote sensing monitoring scheme for the ecological restoration in the study area.
