 摘要： [Objectives] To study the factors influencing the tourism economy in Henan Province. [Methods] Using tourism-related data from Henan Province covering the period from 2000 to 2020, this study constructs a regression model based on multivariate statistical methods to investigate the determinants of the tourism economy. The dependent variable in the model is the domestic tourism revenue of Henan Province, while the independent variables comprise the number of tourist arrivals, total operational railway mileage, the number of travel agencies, and the per capita disposable income of urban residents. [Results] Both the total railway mileage and the per capita disposable income of urban residents are the primary factors influencing the development of Henan’s tourism economy. [Conclusions] It is recommended to reduce uncertainty and liquidity constraints to mitigate residents’ precautionary savings behavior, actively expand domestic demand to leverage tourism as an economic driver, and improve infrastructure to support tourism development.

 摘要： The conversion of waste resources into fertilizer represents a crucial strategy for optimizing waste utilization and attaining "carbon peak and neutrality" objectives. This approach not only effectively mitigates greenhouse gas emissions but also enhances the organic matter content in soil, thereby supporting the advancement of sustainable agriculture. Currently, the principal fertilizer production technologies utilizing solid waste resources encompass hydrothermal fertilizer production, aerobic fermentation, wrapping fertilizer production, micro-storage fertilizer production, and biochemical rapid decomposition. This paper examines the applicability and limitations of these technologies in practical contexts, and anticipates their developmental trends and future prospects. It aims to offer practical guidance and constructive support for the resource utilization of solid waste and the sustainable development of related industries.

 摘要： This paper systematically reviews the mechanisms by which shading influences the accumulation and distribution of plant biomass, leaf morphology and structure, and plant height growth. Generally, plants adapt to low-light environments by modifying their biomass allocation strategies, for example, by reducing the root-to-shoot ratio. The morphology and anatomical structure of leaves exhibit significant responses to shading, typically characterized by an increase in leaf area and specific leaf area, a reduction in leaf thickness, decreased stomatal density, thinning of the palisade tissue, and a lowered ratio of palisade to spongy tissue. These changes serve to optimize the capture and utilization of light energy. Additionally, shading generally promotes an increase in plant height, but the specific response patterns vary depending on the species and their respective shade tolerance thresholds. The paper ultimately emphasizes that future research should integrate multiple environmental factors for long-term observation to more comprehensively elucidate the mechanisms by which plants adapt to the light environment. This approach will provide a theoretical foundation for the practices of understory planting and urban greening.

 摘要： This paper examines World Geopark in South Korea as a case study. It begins by outlining the geological and tectonic background of the Korean Peninsula, whose basement consists of Archean to Paleoproterozoic rocks. These rocks form three continental blocks and constitute a rich geological foundation shaped by multi-stage evolution. The distribution and characteristics of global geoparks are then analyzed. As of 2025, South Korea is home to seven UNESCO Global Geoparks (designated between 2010 and 2025), which feature diverse landforms such as volcanic, sedimentary, and structural formations, with some sites also encompassing cultural relics. Finally, the study highlights that 25 of South Korea’s national parks have not yet applied for geopark status and thus hold significant potential. Due to differing evaluation criteria between UNESCO Global Geoparks and South Korea’s national parks, future applications involving multiple parks could expand the scale of geoparks, providing valuable insights for geoscience research and park development across East Asia.

 摘要： [Objectives] To evaluate the performance of two rapid chromogenic media for the detection of Bacillus cereus in milk powder, and verify the media’s inclusivity, exclusivity, and accuracy, and to assess their applicability for the quantitative detection of B. cereus. [Methods] B. cereus in milk powder samples was quantified using two rapid chromogenic media in combination with the national standard method. Agreement between the quantitative results from the three methods was subsequently assessed for agreement via a paired t-test. [Results] No significant differences were observed between the bacterial counts yielded by the two rapid chromogenic media and the national standard method (P>0.05), with excellent agreement between them. [Conclusions] The method of rapid chromogenic culture medium is rapid and simple.

 摘要： Spider mites are significant pests in agricultural production. The increasing resistance of spider mites, along with environmental pollution and ecological imbalance caused by their control, is primarily attributed to the long-term use of chemical acaricides in agriculture. In contrast, bioactive substances of biological origin offer advantages such as wide availability, environmental friendliness, and low tendency to induce resistance, making them a research hotspot for spider mite control. This review summarizes recent advances in the use of plant-derived active compounds (exemplified by extracts from Veratrum rhizomes), RNA interference (RNAi) technology, and microorganism-derived active substances for controlling spider mites. These bioactive agents exert acaricidal effects by disrupting the nervous system, interfering with metabolic processes, or silencing key genes in mites, demonstrating favorable efficacy and considerable potential for development. However, challenges remain, including poor environmental stability, slow action, high production costs, and insufficient understanding of their effects on non-target organisms. Therefore, future research should focus on the screening and development of novel bioactive substances of biological origin, elucidation of their mechanisms of action, optimization of formulation technologies, and assessment of their ecological safety. These efforts will provide valuable insights for promoting the advancement of bioactive substances and supporting sustainable agricultural development.
