资源简介：
The values are based on cumulative grade range for five factors: i) vegetation height, ii) proportion of bare ground, iii) proportion of vascular plants and iv), carbon content in soil surface horizons and v) soil erosion. Each grade range results in a GL-value, ranging from 1 (very poor condition) to 5 (excellent condition).
