Absztrakt (kivonat)

The issue of groundwater depletion which affecting the Great Hungarian Plain, especially its Sand Ridge region, brings about severe ecological and economic consequences. Research on the possible causes behind this phenomenon has been ongoing for decades, yet determining their relative importance remains a subject of scientific debate to this day. Several authors highlight the significance of afforestation in reducing groundwater levels. This can occur through two mechanisms: water uptake by vegetation and reduction in recharge from precipitation (interception, soil moisture uptake). We examined these mechanisms based on soil moisture and groundwater data measured at depths of 90, 150, and 200 cm with high temporal resolution at a black locust (Robinia pseudoacacia) and a black pine (Pinus nigra) stands in our sample area which was established in the Sand Ridge at Kecskemét-Méntelek. Based on the data, it can be concluded that there is no direct or indirect water uptake from the groundwater, presumably due to a significant horizontal distance between the root zone and the groundwater. In the case of soil moisture, the drying effect of forest stands is clearly evident in the shallower layers during the growing season. However, based on soil moisture data from deeper layers, it can be stated that theoretical groundwater recharge from precipitation is only possible beneath the black locust stand. The apparent contradiction can presumably be explained by the influence of macropores formed by the root system. This is supported by the significant difference observed between the black locust and black pine stands. Our conclusion is that forest stands can have significantly different local effects on groundwater levels. Therefore, rather than making general conclusions, understanding the processes behind these effects requires monitoring data examining several elements of the specific hydrological system. © Szerző(k) 2024.
