中亚-西亚地区荒漠化关键要素数据集（阿姆河流域）（1990、2000、2010）

中亚-西亚地区荒漠化关键要素数据集（阿姆河流域）主要包括：阿姆河流域湖泊分布图、植被覆盖度图和净初级生产力图，其中阿姆河流域湖泊分布图和植被覆盖度图空间分辨率为30m，时间分辨率为1990、2000和2010年三期；净初级生产力图空间分辨率为500m，时间分辨率为2001和2010年两期（由于1990年还没有发射MODIS卫星，所以没有1990年数据）。数据由中国科学院新疆生态与地理研究所遥感与GIS重点实验室生产，生产费用由“中国科学院战略性先导科技专项XDA20030101资助”。阿姆河流域湖泊分布和植被覆盖度数据是基于1990年、2000年和2010年TM/ETM遥感影像解译和计算得出。净初级生产力数据是基于MODIS影像数据计算的净初级生产力（NPP）年累计值。

Key Desertification Factor Dataset of Central Asia-West Asia Region (Amu Darya Basin) mainly includes three types of datasets for the Amu Darya Basin: lake distribution map, vegetation coverage map and net primary productivity (NPP) map. The lake distribution map and vegetation coverage map have a spatial resolution of 30 m, with data covering three temporal phases: 1990, 2000 and 2010. The net primary productivity map has a spatial resolution of 500 m, with data covering two temporal phases: 2001 and 2010, as no MODIS satellite was launched in 1990, so no valid data for this year is available. This dataset was produced by the Key Laboratory of Remote Sensing and GIS, Xinjiang Institute of Ecology and Geography, Chinese Academy of Sciences, with funding support from the Strategic Priority Research Program of the Chinese Academy of Sciences (Grant No. XDA20030101). The lake distribution and vegetation coverage datasets were generated through interpretation and calculation of TM/ETM remote sensing images acquired in 1990, 2000 and 2010. The net primary productivity datasets are annual cumulative NPP values calculated based on MODIS remote sensing imagery.
