Soil phosphorus maps in China in the 1980s and 2010s

We evaluated the changes in topsoil available P (AP) and total P (TP) in China’s forestland, grassland, paddy fields and upland areas during the 1980s-2010s. Soil AP density and TP density maps in the 1980s and 2010s were produced by random forest models.

本研究评估了20世纪80年代至21世纪10年代期间，中国林地、草地、水田与旱地的表层土壤有效磷（available P, AP）及全磷（total P, TP）的变化情况。20世纪80年代与21世纪10年代的土壤有效磷密度、全磷密度空间分布图，均通过随机森林（Random Forest）模型生成。
