Abstract The loess hilly region is one of the most fragile areas in China. Many ecological restoration projects this are equivalent to simple afforestation and grass planting, with large investment low benefits. Based on concept reference ecosystem, study uses remote sensing data vegetation community survey Wanhuigou catchment, applies methods such as redundancy analysis GeoDetector explore characteristics topography, soil, so provide standards for damaged or degraded ecosystems a small watershed. Thirteen typical representative selected evaluate degree ecosystem damage resilience, divided into four categories according evaluation results ecosystems. Corresponding measures protection conservation, natural restoration, auxiliary regeneration, reconstruction adopted under different scenarios target, effectiveness implementation assessed. show that combination conditions elevation slope have very important influence distribution In process it necessary deeply grasp soil species diversity within same among communities, well their interrelationships. Adaptive situations conducive sustainability restoration. Given complexity habitat plant types certain universality, which can comprehensive management other watersheds region, achieve sustainable construction harmonious development between humans nature.

Afforestation is widely acknowledged as an effective approach for enhancing ecological conditions. Considering the challenging environment on Loess Plateau, prioritizing soil and water conservation functions in stands crucial. The study aimed to ascertain future development direction of forestry Plateau by examining two representative forest types: planted (Robinia pseudoacacia pure Pinus tabulaeformis forest), natural secondary (a mixed Quercus liaotungensis Populus davidiana). assessment centered types, encompassing function (rainfall distribution changes multi-year moisture storage (0–200 cm)), (soil physicochemical properties), understory plant diversity stability. results indicated that forests outperformed terms effectively converting more precipitation into moisture, reducing runoff, maintaining higher storage. Additionally, exhibited superior compared forests, characterized porosity nutrient properties. variation community structure between shrub herbaceous layers was significant among different than within each (P < 0.05).

Abstract The forest canopy affects the water entering ecosystem by intercepting rainfall. This is especially pertinent in forests that depend on rainfall for their ecological needs, quantifying and simulating interception losses provide critical insights into hydrological processes. In semi‐arid areas of Loess Plateau, afforestation has become an effective restoration measure. However, process these plantations still unclear. To quantify model plantations, we conducted a two‐year redistribution measurement experiment three typical including deciduous broadleaf plantation ( Robinia pseudoacacia ) two evergreen coniferous Platycladus orientalis Pinus tabuliformis ). Based this, revised Gash was used to simulate losses, applicability across varying types further compared verified. clarified proportions throughfall gross , were 84.8%, 70.4%, 75.6%; corresponding, stemflow 2.0%, 2.2%, 1.8%; 13.2%, 27.4%, 22.6%, respectively. dominant pattern during characterized low‐amounts, moderate‐intensity, short‐duration, which highest observed.

Introduction This study evaluates the effectiveness of soil reconstruction and restoration in Jiangcang coal mining area on Qinghai-Tibet Plateau, where harsh environmental conditions pose significant challenges to ecological restoration. Methods Two phases were implemented, with outcomes assessed based vegetation coverage, species diversity, biomass, properties, community similarity. Results The results demonstrate that significantly improved fertility, stability without noticeable degradation over time. use sheep manure increased diversity by introducing native seeds, addressing shortage suitable grass alpine areas. Comparatively, second phase restoration, which included reconstruction, has elevated coverage 80%, matching natural background levels, also demonstrated superior terms stability, nutrient content, other aspects compared traditional methods. While aboveground biomass showed rapid recovery, belowground lagged, indicating a need for longer-term Restored slopes exhibited higher similarity meadows platforms, suggesting dominance artificially seeded platform areas hinders reproduction species, is unfavorable evolution diversity.

Due to the differences in green water (GW) budget patterns of different vegetation, improper vegetation restoration may not only fail improve ecological environment but also cause irreversible damage ecologically vulnerable areas, especially when continues be implemented future, and pressure on scarcity increases further. However, there is a lack standardized research recharge, consumption, efficient use GW typical vegetation. This makes results vary cannot provide direct support for management decision-making. Therefore, this study, 30-year-old woodlands (R. pseudoacacia P. orientalis) two grasslands (I. cylindrican M. sativa) that are similar each other except species were selected headwater catchment rain-fed agricultural area. A new concept assessment framework was constructed study long-term revegetation using combination field experiments model simulations during 2019–2020 growing season.
