| Zusammenfassung |
| The investigation in the catchment of the Mulde (51°0'55" N,
13°15'54" E Saxony, Germany) researches the effect of
afforestation measures on the soil hydraulic properties. The concept of a
"false chronosequence" was used to quantify the time-dependent dynamical
character of the forest impact. Four adjacent plots were identified at a
test location with comparable pedological start conditions and a set of tree
stands of different age: (1) arable field (initial state); (2) 6-year-old
afforestation; (3) 50-year-old afforestation; (4) ancient natural forest
("target" stocking). Water retention curves and unsaturated conductivities
were analysed in the lab. In the field, the undisturbed infiltration
capacities were measured quantitatively (hood infiltrometer) and
qualitatively (brilliant blue tracer). Pronounced differences between all 4
plots were detected. The afforestation causes an increased infiltration and
soil water retention potential. Especially the topsoil layers showed a
distinct increase in conductivity and portion of coarse/middle pores. The
influence of these changes on rainfall-runoff calculations at the test
location was analysed in this study. |
