Impact of Mining Area Steep Slope Conditions on the Soil and Water Conservation Benefits of Ecological Restoration

Water, Journal Year: 2025, Volume and Issue: 17(2), P. 256 - 256

Steep slopes, characterized by their high gradient and limited soil water resources, pose significant challenges to plant colonization. Consequently, the ecological restoration of steep slopes is one major in field mine site rehabilitation. This study evaluated impact slope conditions on effectiveness during early stages restoration. Two with different conditions, excavated filled slope, were selected, restored hanging net spraying measures. The unrepaired was used as control. results showed that has a effect for conservation; runoff sediment reduced 61.38% 99.28%, respectively, infiltration increased 104.26%, compared untreated slopes. Furthermore, could effectively reduce erosion dynamics erodibility, alter runoff–sediment relationship thereby substantially influencing yield processes Notably, reduction measures more than 19.06% 53.77% lower respectively. From conservation perspective, suitable application rock However, further research needed evaluate its applicability

Distribution Pattern and Assembly Process of Fungal Communities Along Altitude Gradient in Sediments of the Yellow River Basin

Journal of Fungi, Journal Year: 2025, Volume and Issue: 11(3), P. 214 - 214

Microorganisms have a profound impact on the stability and ecological health of aquatic environments. Fungi, as important components river ecosystems, play critical roles decomposers symbionts. A comprehensive understanding mechanisms underlying fungal community assembly is essential for effective conservation management ecosystems. However, distribution patterns process communities along elevation gradients in sediments remain poorly understood. In this study, ITS amplicon sequencing, neutral model, null model were employed to analyze processes altitudinal gradient Yellow River. The results indicated that Ascomycota (47.79%) Basidiomycota (15.68%) identified dominant phyla sediments, collectively accounting 63.47% total relative abundance community. three different gradients, diversity (Shannon) showed gradually decreasing trend with increasing altitude. co-line networks exhibited positive interactions had more complex compact Tibetan Plateau area (YRA). Environmental factors played an role shaping structure communities, lead (Pb), nitrogen (TN), silt, organic carbon (TOC) being main driving changes structure, contributing 15.5%, 12.3%, 10.7%, 10.2%, respectively. process, deterministic found dominate, homogenizing selection most (69.66%). These research help us understand assembly, also provide scientific basis biodiversity rational use biological resources.
