Rock Outcrop (ROC) is very common in terrestrial ecosystems, typically in karst. ROCs play both positive and negative effects in ecosystems. They may collect precipitation (including throughfall), wet/dry deposition, host bacteria, fungi, muss and lichen, and even vascular plants. Both plants and their growing matrixes on ROCs differ greatly from their nearby soil patches. Water and organic and inorganic materials received and produced on ROCs is easily redistributed to their nearby soil patches, put strong influence on water and elements process in soil patches, and thus, affect the plants growing on soil surface. However, quantitative study on water and materials received and produced is scarce, nor on the eco-hydrology effect, thus, blocking the explanation of karst ecosystem succession, block the strategy formulation on countermeasures of karst desertification.
