This study had three objectives: (1) to consolidate poverty alleviation achievements and connect them with the current rural vitalization strategy; (2) to inaugurate agricultural modernization development in rural areas of the Poyang Lake Ecological Economic Zone, an important grain production area in China, during the Fourteenth Five-Year Plan in China (2021–2025); and (3) to assess the ecological function area and economic development highland in Jiangxi Province. This study aimed to examine cultivated land multifunctionality (economic, social, and ecological functions) and explore its evolution and coordination in the context of increasingly serious contradiction between man and land in China. This study established an index system based on a mechanical model to evaluate cultivated land multifunctionality, the spatiotemporal pattern of multifunctionally cultivated land, and the coordination among sub-functions in different periods. Its results were as follows: (1) the cultivated land’s multifunctional value generally increased from 2016 to 2020, with spatial characteristics of highland surrounding a lake; (2) the cultivated land functions’ coordination values were generally better in 2020 than in 2016, showing a generally positive development trend; (3) changes in cultivated land function were concentrated in Quadrants Ⅰ, Ⅱ, and Ⅵ; and (4) the ecological function had the advantage in the study areas. Study conclusions were as follows: (1) the development of cultivated land multifunctionality has achieved notable successes through the significant benefits of an ecological economy; (2) the coordination of the cultivated land’s economic, social, and ecological functions has increased dramatically; (3) the ecological significance in the Poyang Lake Ecological Economic Zone, whose ecological economy was flourishing, was outstanding; and (4) most importantly, it supports implementing the rural vitalization strategy in the Fourteenth Five-Year Plan in China.

Biotechnology assumes a paramount role in addressing micronutrient deficiencies. The promotion thereof and the augmentation of public awareness are indispensable for implementation. The advancement of big data presents challenges due to the plethora of information and the constrained processing capacity, thereby inducing difficulties in consumer decision-making. The study is obliged to intensify information dissemination to empower consumers to apprehend the value of selenium-enriched products as an integral constituent of positive nutrition guidance. The study undertook an experiment related to nutrition information acquisition, in which participants provided relevant interferences. The study utilized the structural equation model (SEM) and fuzzy set qualitative comparative analysis (fsQCA) to analyze the data. The study arrived at three research conclusions. Firstly, the furnishing of valuable information constitutes a significant factor in motivating consumers to purchase selenium-rich agricultural products. Secondly, the communication of brand information holds crucial significance in shaping the perception of product advantages and plays a salient role in the promotion and construction of selenium-rich agricultural products. Finally, the dissemination of health information can be incorporated into the process of promoting selenium-rich agricultural products. This conforms to the urgent necessity to address hidden hunger and establish a value identity.

The Giant Panda (Ailuropoda melanoleuca) is a flagship species for endangered wildlife conservation and is a specific relic species in China. Its habitat conservation has received widespread attention around the world. Since 2010, the phenomenon of an aging labor force gradually appeared within the Giant Panda Nature Reserve and its surrounding communities. Under the new labor force structure, households’ resource utilization behavior has had different characteristics, which has led an evolution in giant panda habitats. This study is based on a questionnaire and geographic data. It reveals the internal mechanisms of households’ resource utilization behavior impacting giant panda habitat patterns under the ongoing trend of labor force aging. The study shows that labor force aging has promoted rising ecological niche widths and falling ecological niche overlaps. These could drive a growth in giant panda habitat globally. From a spatial perspective, nature reserves with lower comprehensive ecological niche widths and higher ecological niche overlaps face greater conflict between conservation and development. However, the phenomenon of labor force aging mitigates these ecological conflicts to a certain extent.

Background: Understanding consumers' behavioral choices after the stimulus of negative events has great significance for repairing consumer perceptions, improving crisis management strategies for negative events, and promoting the food industry’s healthy development. Methods: Based on the "stimulus-organic-response" (SOR) theory, this study constructed a consumer purchasing-behavior model stimulated by negative events and analyzed the influence mechanism of internal stimulus, external stimulus, and consumer characteristics on consumers' negative emotions and selenium-enriched agricultural products purchasing behavior. Conclusions: The empirical analysis produced the following conclusions. ① Negative perceptions and media disclosure not only can directly predict consumers' purchasing behavior with Se-enriched agricultural products but can also predict consumers' purchasing behavior with Se-enriched agricultural products through the mediating effect of negative emotions. ②There is no effect of negative emotion between preferences and consumers' purchase of Se-enriched agricultural products. This is explained by the current online and offline purchase channels, which expand the space of consumer choice. Additionally, in the digital era, consumers are more likely to obtain product information and guidance from relatively professional or targeted opinions, and their purchasing preferences tend to be decentralized and personalized. The influence of lay belief, impulse buying, and herd behavior on consumer purchasing has gradually decreased. ③ External intervention cannot moderate the relationship between negative emotion and purchase. Findings indicated that in the digital era, the rise of we-media, the reduction of information-acquisition cost, and the rise of anti-authority thoughts all lead consumers to distrust authority interventions and consequently, they were more inclined to trust the opinions of non-institutional and non-academic opinion leaders such as celebrities with massive followings.
