Outputs from multiple regression analysis of climatic, edaphic and vegetation factors contributing to HLD in the arid and semi-arid grassland of northern China.

Note: Three independent stepwise models were constructed by restricting to plant variables (plant richness, plant coverage, plant Simpson index), climate variables (MAP, MAT) and soil variables (pH, SOC, available P, available N, clay, silt). The fourth stepwise model introduced all variables (n = 50).
