    including landscape organization assessment (LOA) and soil surface assessment (SSA). Firstly, we set up a 50m transect running directly up and down the slope and mapped patches and interpatches on this transect. We regarded the place where resources could be accumulated as patches, like grass, shrubs, logs or trees. Then we made soil surface assessment by choosing 3 points in each patch type randomly and collecting 11 indicators which can reflect soil quality. Hillslope scale data could describe…
