 摘要： This paper examines the tourism economy of Zhejiang Province, exploring the pathways and mechanisms for its transformation and upgrading under the initiative of innovative development in the cultural and tourism market. In 2024, Zhejiang’s tourism revenue reached 827.5 billion yuan, surpassing that of Hunan Province, the second-ranked region, by 1.3 billion yuan, ranking first in China. The study finds that despite its leading scale, Zhejiang’s tourism economy still faces challenges such as product homogenization, insufficient digital integration, and inadequate regional coordination. Guided by the concepts of cultural-tourism integration and innovation-driven development, this paper proposes an integrated transformation framework based on four dimensions: digital empowerment, business convergence, policy synergy, and brand enhancement. Specific strategies are also outlined, including the development of smart cultural tourism, cultural-tourism IP creation, cross-regional cooperation, and international marketing. The research provides theoretical insights and practical references for promoting high-quality development of the tourism economy in Zhejiang Province and across China.

 摘要： [Objectives] To make a systematic analysis was conducted on the spatiotemporal evolution characteristics of urban land expansion in the region. [Methods] Utilizing land use data from five temporal points (1980, 1990, 2000, 2010, and 2018), the study applied expansion speed, expansion intensity index, and fractal dimension model for analysis. [Results] Regarding expansion speed, the period from 1980 to 2000 represented a phase of low-speed expansion, followed by a rapid expansion phase from 2000 to 2010. Expansion speed subsequently moderated from 2010 to 2018, marking a transition to a medium-speed expansion phase. Spatially, the expansion of Linyi urban district was most pronounced, displaying contiguous sprawl centered on the old urban core. Local expansion patterns were identified as belonging to three types: strip-like, sprawling, and leapfrog development. An analysis of land use conversion revealed that approximately 62.93% of the newly expanded urban land was derived from cultivated land, with industrial/mining/residential land and grassland representing the secondary sources. [Conclusions] Urban expansion in the study area demonstrates an evolutionary trend characterized by initial rapidity followed by stabilization, and the overall spatial structure remains relatively intensive.

 摘要： Under the strategic framework of comprehensively advancing rural revitalization, this study employs Zaozhuang City in Shandong Province as a case study to systematically analyze its practical initiatives in providing community services for rural persons with disabilities. Research indicates that Zaozhuang City has developed a three-tiered service network known as “Rukang Home” and has explored localized models including the “integration of rehabilitation and medical care”, “digital empowerment”, and “supported employment”. Nevertheless, significant challenges persist, such as a structural mismatch between supply and demand, a shortage of qualified professionals, interruptions in sustainable funding, and fragmented institutional governance. To address these challenges, it is essential to shift the conceptual framework from mere “support” to “empowerment”, establish an integrated service delivery system, promote localized talent development, create a diversified financing mechanism, and enhance intelligent services through the adoption of digital inclusiveness.

 摘要： Cyanobacterial blooms have emerged as a significant issue in global freshwater ecosystems. Their presence in agricultural irrigation water sources poses potential risks to crop production, the quality and safety of agricultural products, and related aspects. This article provides a systematic analysis of the current research on cyanobacterial blooms in agricultural irrigation water, focusing on the occurrence and driving factors of cyanobacteria and their toxins in irrigation water bodies, the accumulation and toxic effects of cyanobacterial toxins in crops, the health risk assessment of agricultural products, and the beneficial utilization and management strategies of cyanobacterial resources in agriculture. According to existing research, microcystins (MCs) are among the most concerning cyanobacterial toxins. These toxins can accumulate in various crops, including lettuce, cucumbers, and rice, thereby posing potential health risks through dietary exposure. Furthermore, factors such as irrigation methods, crop species, and growth stages significantly influence the extent of toxin accumulation. This review seeks to provide a scientific foundation for the safe management of agricultural water use, the quality assurance of agricultural products, and the risk assessment and control of cyanobacterial blooms.

 摘要： Climate change-induced spatiotemporal restructuring of precipitation profoundly impacts the ecological processes of cultivated land in Henan Province's core grain production area. This paper systematically reviews the characteristics of ecological responses in cultivated land and the technological achievements in quality enhancement within this region. Studies reveal that the northward shift of precipitation isohyets has intensified the "spring drought and summer waterlogging" pattern, with prominent issues of soil erosion and secondary salinization; the cultivated land quality grade shows an annual average decline of 0.05–0.10 grades. To address these challenges, the research team has developed a comprehensive technological framework encompassing "ecological process identification — zoned remediation — monitoring and early warning — big data support". Demonstration applications demonstrate that this system has led to an average improvement of 0.8 grades in cultivated land quality, an average grain yield increase of 750–1,500 kg/ha, and a water-saving rate of 40% in irrigation. Current limitations include insufficient technological adaptability; future efforts require strengthening the development of adaptive technologies and intelligent upgrades.

 摘要： Urban biodiversity is a critical foundation for the health and sustainable development of urban ecosystems. This paper systematically reviews the conceptual evolution and theoretical framework of urban biodiversity, providing an in-depth analysis of its connotative composition, including core elements such as biological components, habitat systems, and environmental factors, as well as spatial scale characteristics and functional attribute dimensions. Addressing the current challenges facing urban biodiversity conservation, this paper proposes a development pathway encompassing five dimensions: survey and monitoring, planning and control, policy and regulation, technological innovation, and social participation, with case studies from both domestic and international contexts. The research indicates that urban biodiversity conservation requires a systematic strategy involving multi-disciplinary collaboration, multi-stakeholder participation, and multi-scale coordination to achieve the goal of sustainable urban development with harmonious coexistence between humans and nature.

 摘要： [Objectives] To comparatively evaluate the quality differences between green (before color turning) and ripe (fully mature) fruits of three Citrus reticulata cultivars: Gonggan, “Shatang” mandarin, and Orah. [Methods] Fruit quality was systematically assessed across three dimensions: External morphology, internal flavor attributes, and nutritional-functional components. Two external appearance indices and three internal quality indicators were determined. [Results] Gonggan and Orah fruits exhibited significantly larger size than those of the “Shatang” mandarin. During the transition from green to ripe stages, the total soluble solids content of Gonggan and Orah was slightly higher than that of “Shatang” mandarin fruit. In green fruits, Orah exhibited the highest titratable acidity (TA), while “Shatang” mandarin had the highest TA content in ripe fruits. Regarding nutritional composition, Gonggan had the highest ascorbic acid content in green fruits, while Orah demonstrated the highest ascorbic acid content at full maturity. [Conclusions] the quality changes of the three varieties not only conform to the general rules of citrus fruit ripening but also exhibit significant variety specificity. Differentiated industrial strategies can be formulated based on the quality characteristics of different varieties.

Through tissue isolation, pathogenicity testing, and morphological as well as molecular identification, three fungal diseases were identified: black spot, round spot, and brown spot. In specific, black spot had the highest incidence (40.98%), and was caused by Nigrospora chinensis. Round spot was caused by Neopestalotiopsis foedans. Brown spot was caused by Pseudopestalotiopsis camelliae-sinensis. 

 摘要： This paper systematically summarizes the pharmacological effects and molecular mechanisms of nardosinone (Nar) by consulting the literature at home and abroad. The results demonstrate that Nar alleviates the inflammatory response in rheumatoid arthritis by inhibiting the TLR4/MyD88/NF-κB signaling pathway, induces ferroptosis in HT-1080 cells by promoting the accumulation of ROS and lipid peroxides, and exerts antiarrhythmic effects by inhibiting INa, Ito, and ICa-L currents in ventricular myocytes and prolonging their recovery time from inactivation. Moreover, it produces antidepressant effects by reducing the immobility time of mice in behavioral despair models, and protects the myocardium by activating the PI3K/Akt/mTOR pathway to inhibit apoptosis. Nar exhibits multi-target pharmacological activity and has application prospects in the prevention and treatment of autoimmune diseases, tumors, cardiac diseases, and psychiatric disorders.
