Description: Das Projekt "Bodenkennwerte und Bodenerosion - Mechanismen der Bodenerosion in Abhängigkeit der Artenvielfalt und -zusammensetzung in subtropischen Wäldern (DFG-Forschergruppe 891 - Teilprojekt 6)" wird vom Umweltbundesamt gefördert und von Eberhard Karls Universität Tübingen, Fachbereich Geowissenschaften, Abteilung Bodenkunde und Geomorphologie durchgeführt. This project seeks to investigate the relationship between biodiversity and soil erosion. Two process systems will be analysed, (a) modification of kinetic energy of precipitation by its pass through the tree canopy and the shrub layer, and (b) connection between surface runoff, sediment transport and changing intrinsic soil properties as a function of biodiversity gradients. Main factors controlling mechanisms of soil erosion under forest are vegetation, soil cover by litter, intrinsic soil resistance against erosion and the given micro-relief of the soil surface. Main experimental components are (a) measurements of the kinetic energy of rainfall with disdrometers and splash cups under different tree species varying in height and architecture, (b) measurements of surface water flow and sediment on runoff plots at different levels of species richness and species composition, and (c) geomorphometric measurement of changes of soil surface micro-elevation and -form in relation to runoff routing. In addition, this project will also be responsible for spatial and pedological aspects of soil genesis, substrate characteristics, landscape development, and land use history. Soil properties analysed at the plot level like soil texture will serve as baseline data for the whole experiment. Finally, the soil erosion project will contribute substantially to the interpretation of soil-related data sets and the synthesis of results on soil-plant interactions, and will help with the high-resolution DEM from laser scanning and photogrammetry. The Chinese partner project concentrates on detection of dynamics in aggregate stability and organic matter composition in soils related to changes in stand canopy, functional traits and species composition, and on the effect of LAI of forests on soil erosion in relation to biodiversity.
