Soil wind erosion is a global problem that leads to increasingly serious regional land degradation, where the need for windbreak and sand fixation services (WSFS) substantial. Inner Mongolia plays an important role in semiarid arid areas severe degradation resulting from soil warrants urgent solution. However, mechanism of influence various driving factors on still not fully studied.

Mowing Facilitated Shoot and Root Litter Decomposition Compared with Grazing

Plants, Journal Year: 2022, Volume and Issue: 11(7), P. 846 - 846

Published: March 23, 2022

Shoot and root litter are two major sources of soil organic carbon, their decomposition is a crucial nutrient cycling process in the ecosystem. Altitude land use could affect by changing environment mountain grassland ecosystems. However, few studies have investigated effects on different altitudes. We examined how land-use type (mowing vs. grazing) affected shoot dominant grass (Bromus inermis) grasslands with altitudes northwest China. Litterbags 6 g or were fixed plots to decompose for one year. The mass loss rate litter, environmental attributes related decomposition, measured. Litter decomposed faster mowing than grazing plots, resulting from higher plant cover moisture but lower bulk density, which might promote microbial activities. Increased altitude promoted was positively correlated moisture, carbon (SOC), β-xylosidase activity. Our results highlight diverse influences positive stronger compared due responses (e.g., aboveground biomass) SOC). Soil nutrients SOC total nitrogen) seemed play essential roles increased at vice versa altitude. Therefore, significantly decreased altitude, slightly mowing. indicated that variously regulate innate differences edaphic conditions along an gradient, exerting complex impacts further influencing grasslands.

Grazing alters ecosystem multifunctionality via changes in taxonomic diversity and functional identity in temperate grassland, China

Global Ecology and Conservation, Journal Year: 2023, Volume and Issue: 42, P. e02323 - e02323

Livestock grazing is the major land-use regime of grasslands, and affects ecosystem structure functioning considerably. However, few studies have examined how intensity impacts multifunctionality (EMF) via biodiversity loss. We studied responses EMF to livestock in a temperate grassland Inner Mongolia, China. Four intensities (i.e., no (NG), light (LG), moderate (MG), heavy (HG)) were chosen based on distance core zones, vegetation soil indications grazing, suggestions from local guides. For each intensity, three plots (10 m × 10 m) placed randomly, plants, soil, four traits present species sampled 1-m2 quadrats plot. analyzed components taxonomic diversity (TD), functional (FD), identity), multiple functions aboveground biomass, belowground water content, organic matter, total nitrogen, phosphorus, available phosphorus), (based averaging approach threshold-based approach) different intensities, relative importance regulating effect EMF.

Published: July 1, 2023

Alpine shrub meadows hold significant importance as grassland ecosystems on the Qinghai-Tibetan Plateau (QTP). They provide a range of vital ecosystem services (ESs) and are commonly utilized summer pastures by herders, resulting in short grazing periods high intensities. Unfortunately, these practices have led to varying degrees degradation, thereby affecting sustainable provision ESs. However, current knowledge regarding changes ESs their characteristics under influence particularly differences between alpine meadow ecosystems, is insufficient. To address this gap, study aimed investigate analyse four within across different levels well explore relationships. The research was conducted pasture located northeastern QTP. findings revealed substantial reduction 85.9% forage supply due degradation meadows. Moreover, regulating experienced decline followed an increase instances heavy degradation. Trade-offs were observed provisioning services, while synergistic relationships identified among services. Degradation exacerbated imbalances whereas light allowed for better equilibrium two. Comparatively, exhibited higher carbon storage displayed greater nutrient water retention It that relationship patterns significantly influenced presence Consequently, safeguarding structural integrity addressing conflicts over essential ensure coordination sustainability outcomes valuable insights management ecological restoration initiatives

Accordingly, this study presents comprehensive analysis impacts disturbance over past two decades, employing dual perspective tourism utilizing econometric existing literature through software as CiteSpace. The results demonstrate following: (1) current focus primarily concentrated fields ecology environmental sciences, topics plant diversity, abundance, well intensity grazing. These areas may represent key direction future research. (2) associated with activities. Moderate can facilitate healthy ecosystems. intermediate hypothesis (IDH) not fully account for effects ecology. At present, still systematic determine ecological indicators under dual-disturbance scenario.
