Summary: The study revealed that vegetation in the Qinghai-Tibet Plateau is sensitive to climate change and livestock population. Post 2000, vegetation in the plateau increased in 63.7% of the area and decreased in 6.7% of the area. Warmer climate and decrease in livestock population contributed to the vegetation recovery.

Summary: Climate is an important factor in determining livability, and this study focuses on climate suitability in high-altitude areas. By adding oxygen content and solar radiation as indicators, the study develops the Climate Suitability Index of Plateau (CSIP) to assess climate suitability on the Qinghai-Tibet Plateau. The results show that the climate becomes increasingly unsuitable from southeast to northwest, and the plateau is divided into four regions based on the CSIP.

Summary: The problem of grassland degradation caused by livestock production is a serious ecological issue worldwide. A model was developed in this study to monitor the intensity of grazing in a typical grazing area of the Qinghai-Tibet Plateau. The model accurately measured the overall grazing pressure on the pasture and estimated livestock pasture utilization, revealing distinct spatial differences in the intensity of grassland utilization.

Summary: Grazing plays a critical role in the sustainable development of grassland. However, there is inadequate research on the relationship between grazing intensity and grassland soil quality in the alpine environment. This study compared different grazing intensities and found that heavy grazing had a stronger negative effect on soil quality in alpine meadows. It suggests that reasonable grazing intensity management is important for maintaining the sustainable development of alpine meadow productivity.

Summary: This study used a metagenomic approach to investigate the distribution, diversity, and potential biogeochemical impacts of DNA viruses in grassland soils on the Qinghai-Tibet Plateau. The results showed that both virus-like particles (VLPs) and microbial abundance increased with average annual precipitation, and soil water content was the main factor influencing VLP abundance. The study also revealed that the order Caudovirales, particularly the Siphoviridae family, was the dominant viral type in the soil, and soil viruses may play a potential role in the carbon cycle on the plateau.

Summary: Cyclophyllidea is the most species-rich order of tapeworms, with significant health impact on wildlife, livestock, and humans. Through collection and sequencing of specimens from rodents in Qinghai-Tibet Plateau, several putative new species were identified. Additionally, three known species were found, suggesting their wide distribution in western China. The divergence time estimates indicate a strong association between species differentiation and biogeographic changes resulting from the uplift of the QTP, supporting the hypothesis of host-parasite co-evolution.

Summary: The study comprehensively analyzed carbon emissions and carbon sequestration from agriculture and animal husbandry on the Qinghai-Tibet Plateau from 1990 to 2015. Results showed significant increases in carbon emissions from agriculture (163%) and animal husbandry (41%), while trends in carbon sequestration varied between the two sectors.

Summary: The carbon sink on the Qinghai-Tibet Plateau (QTP) has weakened during the past four decades, especially in the non-permafrost regions. Simulation results suggest that future climate change may shift the carbon sink on the QTP to a carbon source.

Summary: By studying a 2,800-year peat record from the northeastern Qinghai-Tibet Plateau, the researchers identified the aeolian origin of archived particles and found that dust input was enhanced during warming periods. They proposed that warming climate may have significant impact on moisture balance and wind strength, leading to more frequent dust activity in the future.

Summary: Livestock grazing can alter biodiversity and ecosystem functions, but the effects on belowground biodiversity, especially soil microbial diversity, are not well understood. A 5-year field experiment in a Tibetan alpine meadow was conducted to examine the responses of soil bacterial and fungal communities to yak grazing intensity. The results showed that grazing intensity significantly changed the composition of soil bacterial and fungal communities, but had no significant effect on microbial alpha-diversity. Various soil and vegetation factors were associated with the soil microbial communities. These findings have implications for grassland management and ecological restoration in alpine ecosystems.

Summary: This study developed an evaluation framework for recreation services in the Qinghai-Tibet Plateau, showing that the landscape aesthetic quality, climate suitability, and recreation utilization in the region were generally low. The limited ecological capacity and poor adaptation to the plateau climate affected the development of recreation services.

Summary: This study integrated the Optimal Land Degradation Index and spatial footprints to investigate changing trends and degradation risks on the Qinghai-Tibet Plateau. The results showed that land improvements were dominant, accounting for 18.83% of the plateau. High-risk degraded land covered an area of 0.55 million km2, while low-risk degraded land covered 0.78 million km2. The spatial distribution of high-risk degraded land varied gradually from scattered small areas to increasingly frequent connected patches.

Summary: This study proposed a temporal fitting algorithm to generate daily seamless surface brightness temperature (TB) data from Soil Moisture Active Passive (SMAP) satellite over Qinghai-Tibet Plateau (QTP). The missing TB observation was reconstructed by combining the overall temporal trend and daily variation. Cross-validation and product comparison results demonstrated the robustness and desirable performance of the proposed method.

Summary: This study analyzes the characteristics of process parameters in three lean gas ethane recovery processes and establishes a prediction and multiobjective optimization model for ethane recovery and system energy consumption. A new method for comparing ethane recovery processes for lean gas is proposed, and the addition of extra coolers improves the ethane recovery. The support vector regression model based on grey wolf optimization demonstrates the highest prediction accuracy, and the multiobjective multiverse optimization algorithm shows the best optimization performance and diversity in the solutions.

Summary: The paper proposes a novel deep learning-based prediction framework, aTCN-LSTM, for accurate cooling load predictions. The framework utilizes a gate-controlled multi-head temporal convolutional network and a sparse probabilistic self-attention mechanism with a bidirectional long short-term memory network to capture both temporal and long-term dependencies in the cooling load sequences. Experimental results demonstrate the effectiveness and superiority of the proposed method, which can serve as an effective guide for HVAC chiller scheduling and demand management initiatives.

Summary: This study uses survey data from the Loess Plateau in China to evaluate the impact of social interaction on the adoption of soil and water conservation (SWC) technology by farmers. The study finds that social interaction increases the likelihood of farmers adopting SWC, and internet use moderates this effect. The positive impact of social interaction on SWC adoption is more pronounced for farmers in larger villages and those who join cooperative societies.
