1 Introduction

The section first clarifies that the purpose of academic writing is to achieve ecological academic communication through multi-party interactions and negotiations with different communities. It then introduces the current state of research on academic writing from an ecological perspective, covering developments in areas such as classroom instruction, language practices, and writing assessment systems. It points out that these studies demonstrate an interdisciplinary integration trend but are insufficient in examining ecological academic communication at the micro-level of academic discourse. The focus then shifts to reporting verbs, explaining their crucial role in academic texts, including functions such as attribution, source connection, evaluation, and evidential support, as well as linguistic features like types of reporting verbs, verb classifications, and tense usage. Finally, it proposes that this study will approach reporting verbs from the perspective of their communicative functions, treating them as a semantic category that constructs dialogic relationships among academic subjects and facilitates knowledge flow, thereby addressing gaps in previous research.

2 The Ecology of Academic Discourse and Research on Reporting Verbs

This section delves into the ecology of academic discourse and its close connection with reporting verbs. First, it analogizes academic discourse to an ecosystem, emphasizing interactions and balance among participants, which include past, present, and future researchers, and how knowledge transmission and innovation drive academic progress. Second, from a perspective integrating linguistics and ecology, and based on the "Hallidayan model," it defines the ecology of academic discourse as the interaction of ecological factors and effective dissemination achieved through linguistic means. Next, it proposes the ecological philosophical view of "multi-party coordination, cyclical symbiosis" to guide the ecological construction of academic discourse, promoting the inheritance and innovation of knowledge. Finally, it elaborates on the key role of reporting verbs in constructing the ecology of academic discourse. Reporting verbs not only connect authors with others but also maintain the dynamic balance within the discourse, facilitating knowledge reproduction and interpersonal relationship regulation, making them an important means to achieve the communicative purposes of academic discourse.

3 Research Design

This section details the research design for studying the ecological construction of academic discourse based on reporting verbs. First, it introduces the analytical framework, emphasizing the pivotal role of reporting verbs in academic discourse and exploring its ecology by analyzing their communicative functions. The study categorizes the ecological attributes of reporting resources into "community-oriented" and "meaning-oriented" to assess the ecology of academic discourse. Next, it describes the corpus building and annotation process. Fifty articles from five international core linguistics journals were selected as the research corpus, and the UAM CORPUS TOOL3 software was used for the manual identification and annotation of reporting verbs. The annotation process includes identifying reporting resources, analyzing their communicative functions, and determining their ecological orientation, ensuring the accuracy and consistency of data annotation.

4 Research Findings

This section systematically presents the usage characteristics of reporting verbs in international journal articles and their effects on ecological construction. The study focuses on the overall distribution of ecologically beneficial reporting verbs and analyzes the communicative functions and ecological orientations achieved by different reporting resources in academic discourse based on their verb types. The findings reveal that academic discourse heavily relies on previous researchers and their existing research, with knowledge production rooted in disciplinary traditions and knowledge bases constructed from past studies, reflecting the cyclical symbiotic model within the academic ecosystem. At the level of reporting agents, authors in international journals tend to cite the voices of academic subjects across different temporal dimensions, showcasing a self-renewing, self-generating open system. The distribution of research content further demonstrates critical inheritance, thorough integration of existing research, and exploration of potential future studies, effectively maintaining the dynamic balance and sustainable evolution within the academic ecosystem.

In the corpus of international journal articles, a total of 1,901 ecologically beneficial reporting verbs were identified, with approximately 52.2 instances per 10,000 words. The conventionality and normativity of these reporting verbs in academic communication, along with their strategic use in specific contexts, indicate that international journal writing tends to employ reporting verbs to facilitate discursive interactions and dynamic balance among different communities, thereby constructing a relatively well-developed ecosystem of academic discourse. In terms of the distribution of communicative functions achieved by reporting verbs, international journal articles show a preference for attribution, establishing connections between current viewpoints and existing research to avoid "source-less" knowledge. Cognitive verbs are not only used for attribution and stance construction but also emphasize verifying the interaction between existing research content and current findings, guiding readers into processes of logical inference and cognitive processing. This multi-dimensional unfolding of functions creates a cyclical flow of argumentation between the author's voice and the cognitive activities of previous research communities, strengthening the rationality of current arguments and highlighting the cognitive authority of academic viewpoints. In the dimension of evidencing existing research, research-type verbs assign weight or limitations to previous findings, regulating academic stances while conveying information. This critical engagement introduces diverse research outcomes into the discourse, fostering intertextuality between current and previous studies and achieving a convergence and dynamic balance of knowledge resources.

Further examining linguistic resources, this section investigates the ecological significance of discourse-type, cognitive-type, and research-type reporting verbs in achieving communicative functions such as attribution, source connection, evaluation, and evidential support, thereby revealing how different reporting verbs promote the coordinated coexistence of multiple voices and the cyclical symbiosis of knowledge at the discourse level. Discourse-type verbs emphasize the process of verbal expression and can achieve the communicative functions of attribution, source connection, evaluation, and evidential support. Cognitive-type verbs describe mental processes, emphasizing researchers' thinking and cognitive activities, primarily achieving the functions of attribution, source connection, and evaluation. Research-type verbs describe the psychological or physiological experiential processes in research behaviors, primarily referring to academic activities themselves—how researchers design, conduct, and discover findings—comm包括 including linguistic resources such as "find," "observe," "show," and "prove." These typically emphasize the objective presentation of research processes and results, achieving the communicative functions of attribution, source connection, evaluation, and evidential support. In academic discourse, these verbs not only convey academic information but also realize unique communicative functions among different academic subjects, facilitating the cyclical flow and symbiotic growth of academic knowledge and promoting the ecological construction of academic discourse.

5 The Ecological Construction of Academic Discourse and Reflections on Ecological Academic Writing

This chapter explores the ecological construction of academic discourse, extending the paradigm of ecological discourse analysis. Focusing on reporting verbs, it constructs a multi-dimensional analytical framework, analyzes the communicative functions of reporting verbs, and reveals the interactive relationships among factors in academic discourse. The study emphasizes the importance of reporting verbs in academic writing, proposes pedagogical suggestions, and points out the ecological roles of reporting verbs in different stages of discourse, thereby promoting the ecological balance and development of academic discourse.

6 Conclusion

This section summarizes the role of reporting verbs in the ecological construction of academic discourse, identifying reporting verbs as key elements. These verbs are categorized into discourse-type, cognitive-type, and research-type, each fulfilling functions such as attribution, stance modulation, and reporting findings, thereby driving knowledge circulation and innovation. The study introduces the concept of "academic discourse ecology," constructs a theoretical framework, and provides guidance for writing practices. Future research can expand on these perspectives.
