青藏高原土地退化数据集（V1.0)

"基于青藏高原不同的退化过程，分别将1990和2015的冻土退化、植被退化、盐碱化、沙漠化、土壤侵蚀过程作为主要的退化类型，选择对高原土地退化影响显著的退化过程进行叠加，评估从1990到2015时期内青藏高原土地退化变化趋势。土地退化类型分类：0 - No degradation；
1 - Salinization；
10 - Permafrost degradation；
11 - Salinization and permafrost degradation；
100 - Soil erosion；
101 - Soil erosion and salinization；
110 - Soi erosion and permafrost degradation；
111 - Soi erosion, permafrost degradation and salinization；
1000 - Desertification；
1001 - Desertification and salinization；
1010 - Desertification and permafrost degradation；
1011 - Desertification, permafrost degradation and salinization；
1100 - Desertification and soil erosion；
1101 - Desertification, soil erosion and salinization；
