青藏高原高寒草地恢复潜力多年均值数据（2001-2019）

青藏高原高寒草地恢复潜力数据（R）是在估计青藏高原草地实际NPP (ANPP）与潜在NPP (PNPP)的基础上，制作的代表2001-2019年青藏高原高寒草地恢复潜力均值的数据。该数据基于2001-2019年气象插值数据与MODIS遥感影像，选用CASA模型计算了青藏高原草地的ANPP，选用Thornthwaite Memorial模型、相似生境法以及Chikugo模型分别估计PNPP。并以2001-2019年PNPP和ANPP逐年差值的均值估计草地恢复潜力。

The Qinghai-Tibet Plateau Alpine Grassland Restoration Potential Dataset (R) represents the mean value of alpine grassland restoration potential on the Qinghai-Tibet Plateau from 2001 to 2019, which is developed based on the estimation of actual net primary productivity (ANPP) and potential net primary productivity (PNPP) of grasslands in this region. This dataset relies on meteorological interpolation data and MODIS remote sensing images from 2001 to 2019. The CASA model was employed to calculate the ANPP of grasslands on the Qinghai-Tibet Plateau, while the Thornthwaite Memorial model, similar habitat method, and Chikugo model were respectively used to estimate PNPP. The grassland restoration potential was finally estimated using the mean of the annual differences between PNPP and ANPP over the period 2001–2019.
