青藏高原湖泊面积年际变化空间分布数据集(2005-2020)
收藏资源简介:
基于重建的青藏高原30米分辨率遥感时间序列数据集QTP-NDVI30,发展了时间序列断点检测方法对高原上所有湖泊面积的年际变化进行了探测,生成了青藏高原湖泊面积增加(Gain)和减少(Loss)的年份的空间精细分布。该数据集可用于分析青藏高原水体变化及其对高原生态服务的影响。相比于其它同类湖泊分布数据,该数据集空间分辨率高(30米),能够刻画青藏高原单个湖泊的扩张和收缩的年际变化,具有其应用价值。
Based on the reconstructed 30-meter resolution remote sensing time-series dataset QTP-NDVI30 of the Qinghai-Tibet Plateau (QTP), this study developed a time-series breakpoint detection method to detect the interannual variations in the area of all lakes on the plateau, and generated spatially refined distributions of the years when lake areas on the QTP experienced increases (Gain) and decreases (Loss). This dataset can be used to analyze water body changes on the Qinghai-Tibet Plateau and their impacts on the plateau's ecological services. Compared with other similar lake distribution datasets, this dataset boasts a high spatial resolution of 30 meters, and can capture the interannual changes in expansion and contraction of individual lakes on the QTP, thereby possessing considerable application value.
