Land Degradation Development Environmental Soil
2019年8月14日 The highly degraded peat soils and hydrological changes observed in the northern part of the GV suggest a potential negative impact from open-pit lignite mining. This supports our main hypothesis that long-term dewatering, as an effect of open-pit mining operations in the period 1982–2009, is the main factor that affects these peat soils.
