Especially for the ecologically fragile inland river basins, EN optimization is of significance in ensuring regional ecological security and virtuous cycle of ecosystems. In addition, EN is a dynamically changing structural system that is more applicable to the regional development by optimizing it from comprehensive future development perspective. EN of Shiyang River basin was constructed on account of the circuit theory, and land use/cover changes (LUCC) of the basin in 2035 was predicted by PLUS model, so as to explore the ecological conservation priorities and formulate optimization strategies. 54 ecological sources (ESs) were identified, covering an area of 12,198 km², mainly in the southern basin. 133 ecological corridors (ECs) with an area of 3,176.92 km² were extracted. 38 ecological pinchpoints (EPs) and 22 ecological barriers (EBs) were identified respectively, which were mainly distributed in the lower basin. To effectively enhance the connectivity of EN in Minqin County, which has the worst ecological environment, we added five stepping stones based on the Ant Forest project. In addition, the optimal EPS is selected according to the development and limitation needs of inland river basins and the threat degree of warning points (WPs) under different scenarios. Scientific and reasonable optimization of future urban layout to prevent WPs can effectively alleviate the contradiction between ecological protection and economic development. The study is intended to provide basis for ecological sustainable development and rational planning territorial space in Shiyang River basin, as well as opinion for EN optimization in inland river basin.</div></div>","PeriodicalId":53163,"journal":{"name":"Research in Cold and Arid Regions","volume":"17 1","pages":"Pages 43-54"},"PeriodicalIF":0.7,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143696209","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The repeated FT disrupted the structure of the RM particles, leading to an increase in the pore space between the soil particles.

However, the mechanism of ecological compensation based on embodied carbon emissions is still poorly understood. Here, taking the Yellow River Basin as the research area, we use the multi-regional input-output (MRIO) model to measure the embodied carbon transfers between its seven urban agglomerations in 2012 and 2017 from the viewpoint of value-added trade benefits. Further, for the first time, the green trade benefits and ecological compensation amounts are analyzed. The results indicate that: (1) The transfer of trade-embodied carbon among the urban agglomerations in the basin showed obvious spatial heterogeneity and geographic proximity effects, and trade-embodied carbon outflows (inflows) had a pattern of \"highest in the midstream, second in the downstream, and lowest in the upstream\". (2) The industry composition of the urban agglomerations in relation to embodied carbon outflows (inflows) was similar, mainly in the service and heavy manufacturing industries.

(4) The pattern of ecological compensation in the basin had shifted from the upstream surplus, the middle and downstream deficit to the midstream deficit, and the upstream and downstream surplus. Therefore, we recommend improving energy structures in high-demand urban agglomerations by adopting clean energy, focusing on decarbonization and energy efficiency in resource-rich regions. Additionally, promoting low-carbon economies, especially in the service and heavy manufacturing industries, implementing differentiated emission reduction strategies, and optimizing carbon compensation mechanisms considering regional disparities and resource endowments are crucial.

This study considered the effects of these properties on the integrity of tunnel structures. By establishing an elastoplastic mechanical model, analytical solutions to the stress and displacement under five different elastoplastic states were derived and compared based on distinct yield criteria. The findings showed that with increasing relative radius, the displacement in the lining elastic zone initially decreased before increasing, whereas the shift in the plastic zone continued to increase. The displacement in the elastic zone of the frozen surrounding rock intensified with increasing relative radius, whereas the shift in the plastic zone experienced a gradual decline. The displacement of the inner wall of the lining was always greater than that of the outer wall, and this phenomenon occurred only after the frozen surrounding rock exhibited a plastic zone. The maximum displacements of the liner in its elastically limited and plastically limited states were 1.39, 1.77, 2.28, and 2.37 mm and 15.93, 25.51, 44.28, and 48.58 mm based on the Drucker–Prager (DP), Mohr–Coulomb (MC), Tresca, and double-shear strength criteria, respectively; the maximum limit displacements of the frozen surrounding rock were 12.74, 20.41, 35.43, and 38.87 mm and 85.32, 103.38, 569.23, and 680.43 mm, respectively.

In this study, we investigated the Maqu alpine meadow, meticulously categorizing it into different grassland types exhibiting varying degrees of degradation based on factors such as vegetation coverage and community, soil characteristics, and landscape features. These classifications included typical grassland, degraded grassland, desertified grassland, and sandy land. In August 2018, we established three quadrats at each sample point and collected soil samples at five depths (surface (0–2 cm), 2–5 cm, 5–10 cm, 10–20 cm, and 20–40 cm) to analyze soil particle size distribution (PSD) and nutrients content. The results revealed a discernible trend: alpine meadow degradation led to selective loss of nutrient-rich soil fine particles, resulting in significant alterations in soil PSD and nutrients, particularly pronounced in grasslands with low degrees of degradation. Moreover, within a specific range of degradation degree, the clay content in the shallow soil of alpine meadow increased with the degradation degree, but it declined when the degradation degree exceeded a certain threshold. Degradation also disrupted the intricate relationship between soil nutrients, with notable variations in their coupling. This difference was also reflected in the influence of soil physical and chemical properties on soil nutrients, with the explanatory power of each environmental indicator on soil nutrients decreasing significantly with increasing degradation. This study systematically analyzed the variation in soil physical and chemical properties throughout the degradation process, revealing the mechanism of soil nutrient imbalance and decline caused by the degradation process.

Therefore, to explore the growth of sea buckthorn seeds, this study analyzed and studied the molecular mechanism of seed germination process of sea buckthorn. To better understand the molecular mechanism underlying seed germination in sea buckthorn, we used transcriptomics to compare gene expression before and after seed germination in <em>H. rhamnoides</em> subsp. <em>sinensis Rousi</em>. We identified 9,988 differentially expressed genes (5,593 upregulated and 4,395 downregulated). A bioinformatics-based analysis revealed that changes in plant hormone signal transduction and starch and sucrose metabolism-related gene expression may regulate seed germination in this species. Notably, the levels of auxin (IAA), cytokinin (CTK), and brassinosteroids (BR) increased during seed germination while those of ABA decreased. Exogenous application of IAA, CTK, and BR promoted sea buckthorn seed germination, while ABA inhibited it. These findings suggested that hormones play an important role in the process of sea buckthorn seed germination.

As transitional climate regions, the QMs exert a significant impact on vegetation. Spring maximum continuous 5-day monthly precipitation (Rx5day) and spring precipitation were the two most significant positive controlling factors affecting vegetation. Specifically, aside from water bodies, grasslands exhibited the largest response to these two factors.
