摘要： 本研究以改编自李娟散文集的影视剧《我的阿勒泰》为研究对象，系统探究跨民族对话在该剧戏剧构建中的作用及其对文化交流与理解的深远影响。通过对剧中跨民族交流场景的细致剖析，揭示其在促进不同民族间相互理解与文化融合方面的巧妙机制。《我的阿勒泰》凭借独特的艺术表现形式，巧妙地将阿勒泰地区的自然风光与人文精神相融合，为观众营造出兼具审美价值与文化内涵的跨民族文化交流空间，使观众在领略自然美景的同时，深刻领略不同民族文化的独特魅力及其内在关联[1]P134。本研究旨在为理解跨民族对话在戏剧构建中的功能提供新的理论视角，并为促进不同民族间的文化交流与理解提供实践层面的有益借鉴。

关键词： Iron analysis  

摘要： This study focused on the long-term AMD-contaminated paddy soils in the Dabaoshan mining area of Guangdong Province. The distribution characteristics of soil iron phases and iron-bound organic carbon were analysed, combining with high-throughput sequencing to examine the effects of AMD irrigation on soil organic carbon sequestration and the response of soil microbial community structure. The results indicated that: ① AMD irrigation led to soil acidification, with accumulation of iron, sulfur and heavy metals in paddy soils. The contents of TOC in paddy soils showed significant positive correlation with TFe, and OCFe. ② AMD irrigation resulted in decreases of soil microbial abundance and diversity. AMD irrigation led to a decrease in the relative abundance of Geobacter in paddy soils, whereas acid tolerant iron and/or sulfur metabolizing bacteria such as Thiobacillus and Thioifustis became the dominant bacteria in paddy soils with the most heavily AMD pollution. ③ RDA analysis identified Fep, TOC, and TFe were the most crucial factors influencing microbial community structure. In conclusion, AMD irrigation brought dissolved iron into paddy soils which was beneficial to soil organic carbon preservation. In addition, AMD irrigation resulted in the formation of microbial community structure that closely related to AMD pollution gradient, the form and content of iron and carbon. © 2025 Chinese Society for Environmental Sciences.

摘要： In this study, swine wastewater was treated using constructed wetland-microbial fuel cell (CW-MFC) technology. The pollutant removal efficiency, bioelectricity generation and microbial community structure were evaluated. The results showed that after treated the swine wastewater by the experimental system planted with umbrella grass (PCW-MFC), the average removal efficiencies of NH4+-N, TP and sulfadiazine (SDZ) were increased by approximately 5%, 10%, and 3% respectively, and the output voltage, coulombic efficiency, and maximum power density were recorded as 415.93mV, 49.10%, and 51.12mW/m3, respectively. The relative abundances of Proteobacteria, Bacteroidetes and Firmicutes were increased by umbrella grass, which played a key role in pollutant removal and bioelectricity generation. © 2025 Chinese Society for Environmental Sciences.
