党的十九大报告中，习总书记强调，要动员全党全国全社会力量，坚持精准扶贫。 随着精准扶贫战略的推进，我国媒体通过大量的宣传片和纪录片对扶贫工作进行宣传 报道，表明了时政媒体及公众对精准扶贫的关注以及对于打赢这场脱贫攻坚战的积极 信念。2021 年由新华通讯社出品的《中国减贫密码》是一部关于中国脱贫工作的大 型纪录片，该纪录片以真实的案例详细讲述了中国脱贫事业所做出的巨大努力以及取 得的显著成就，充满积极的基调。本文试图从多模态和积极话语分析的角度对其进行 研究，一方面使观众对中国扶贫有深刻的理解并对其产生积极态度，另一方面也对讲 好中国扶贫故事有一定的借鉴意义。

Martin 提出的评价理论和 Kress & Van Leeuwen 提出的视觉语法理论是对多模态 语篇中语言模态和图像模态进行积极话语分析的重要理论基础。本研究以这两个理论 作为理论框架，借助分析工具 UAM Corpus Tool 和 ELAN，研究该纪录片中语言模态 和图像模态如何构建积极话语。

研究发现：语言模态主要通过态度系统向观众传达积极意义，尤其是通过鉴赏资 源对扶贫工作进行积极描述，传达出积极意义；其次，在介入系统中，通过使用对话 拓展资源，引入外部声音对中国扶贫的积极评价来传达积极意义；在级差资源中，通 过语势资源真实地呈现了中国扶贫取得的伟大成就。对于图像模态的再现意义，影片 主要通过叙事过程呈现人们的动作、目光和言语心理过程向观众传递出他们对于脱贫 后生活的满意；在互动意义中，影片首先通过提供行为向观众传递扶贫工作的信息， 其次通过近景和水平视角，不仅详细地向观众展现了人们生活水平的提高，而且使影 片中人物与观众之间形成平等友好的关系，最后大量高感官情态也向观者展现了纪录 片的真实性；在构图意义中，首先使用较多的左右结构给观者提供新信息，使观者对 精准扶贫有深刻的了解，其次通过位置、大小和色彩突出图像的重点内容，吸引观众 注意力，最后通过框架分割不明显的图像体现图像参与者之间相互和谐的关系。基于 以上分析，本研究认为：类 似主题的影片可通过鉴赏、拓展和语势资源积极打开对 话空间，使用具体数据给观众积极的感受；通过叙事过程、近景、水平视角以及高感 官情态增强观众与影片中人物之间的互动关系。

本研究丰富了积极话语分析的研究范围，同时也对如何讲好中国扶贫故事有一定 的借鉴意义。

In the 19th National Congress of the Communist Party of China, General Secretary Xi stressed that it is necessary to mobilize the whole Party and society to target poverty alleviation. With the promotion of target poverty alleviation, China’s media carried out a large number of propaganda films and documentaries to report poverty alleviation work, which shows the media’s concern for poverty alleviation and their belief in overcoming poverty. China: Prescription for Poverty, produced by Xinhua News Agency in 2021, is a large-scale documentary on China’s poverty alleviation. It details the great efforts and remarkable achievements of poverty alleviation with real cases and is full of a positive tone. This thesis studies it from the perspective of multimodality and positive discourse analysis. It gives the audience a deep understanding and positive attitude towards it and provides implications for telling China’s poverty alleviation.

In multimodal discourse analysis, Martin’s Appraisal Theory and Kress & Van Leeuwen’s Visual Grammar are important theoretical foundations for positive discourse analysis of text and image mode. This study takes these two theories as the theoretical framework and uses UAM Corpus Tool and ELAN to study how the text mode and image mode construct a positive discourse in documentary.

It is found that: text mode conveys positive meaning to the audience mainly through the attitude system, especially through the appreciation resource to describe the poverty alleviation work positively. The engagement system uses the expansion resources to introduce the external voices’ positive comments on China’s poverty alleviation. The graduation system mainly uses force resources to present great achievements of poverty alleviation. The representational meaning in image mode mainly uses narrative process to show people’s actions, reactions and verbal and mental processes to express people’s satisfaction with their present life. In interactive meaning, it firstly conveys the information of poverty alleviation through the offer act, then through the close-up shot and medium angle, not only shows the improvement of people’s living condition in detail but also form an equal and friendly relationship between the audience and people in documentary. Finally, high modality also makes the documentary more authentic. In compositional meaning, it mainly uses left-right composition to provide the audience with new information, giving them a deep understanding of poverty alleviation. Secondly, the key points of the images are highlighted through the salience, such as position, size and color, to attract the viewer’s attention. Finally, the connection of framing reflects the harmonious relationship between the participants of the images. Based on the above analysis, this study suggests that we can use appreciation, expansion and force resources to expand the dialogue space, using factual data to give viewers a positive feeling in films with similar themes. Enhance the interaction between the audience and the participants in the documentary through the narrative process, close-up shot, medium angle and high modality.

This study enriches the research of positive discourse analysis and has implications for telling China’s poverty alleviatio
