植物保育科學文獻之引文網絡分析

Abstract

植物保育對於維護生物多樣性、確保生態系功能及維持生態系服務至關重要。然而，植物物種與生態群落正面臨棲地退化、氣候變遷、土地利用集約化、生物多樣性喪失及其他環境變化所造成的相互關聯壓力。儘管針對上述問題的科學研究已大幅增加，相關文獻仍分散於生態學、保育、管理及監測等不同研究領域，因而增加了辨識該領域主要研究主題、概念關聯及研究優先方向的難度。

本研究採用文獻計量分析與關鍵詞共現圖譜分析，探討自 Web of Science 核心合輯（Web of Science Core Collection）所選取的植物保育相關文獻，並使用 VOSviewer 1.6.20 版建構及視覺化關鍵詞共現網絡。最終網絡包含 82 個關鍵詞、1,963 條連結，總連結強度為 6,426。分析結果形成四個主題群集，分別為生物多樣性保育、管理與生態系服務；物種多樣性與生態系功能；氣候變遷、環境動態與植被反應；以及生物多樣性監測、族群趨勢與生態指標。

研究結果顯示，生物多樣性、保育、多樣性、物種豐富度、管理、氣候變遷、生態系服務、生態群落及生態動態等概念，在所選文獻中佔有重要位置。關鍵詞網絡亦顯示，保育管理、生態系功能、環境變遷與生物多樣性監測之間存在密切關聯。對這些模式進行質性詮釋後發現，相關文獻將長期植物保育視為一項相互關聯的生態與管理挑戰，需要結合生物多樣性保護、生態系復育、對環境變遷的調適性回應、持續監測，以及以實證為基礎的保育規劃。

本研究透過系統性整理所選文獻的概念架構，辨識出未來可能需要加強整合的研究領域。研究結果所呈現的是學術關注程度與關鍵詞之間的關聯模式，而非保育成效或因果關係的直接證據。

Plant conservation is essential to biodiversity preservation and the maintenance of ecosystem functions and services. However, plant species and ecological communities face interconnected pressures arising from habitat degradation, climate change, land-use intensification, biodiversity loss, and other environmental changes. Although scientific research addressing these concerns has expanded considerably, the literature remains distributed across multiple ecological, conservation, management, and monitoring domains. This fragmentation makes it difficult to identify the principal themes, conceptual relationships, and research priorities characterizing the field.

This study applies bibliometric analysis and keyword co-occurrence mapping to a selected body of plant-conservation literature retrieved from the Web of Science Core Collection. VOSviewer version 1.6.20 was used to construct and visualize the keyword co-occurrence network. The final network consisted of 82 keywords connected by 1,963 links, with a total link strength of 6,426. The analysis generated four thematic clusters: Biodiversity Conservation, Management, and Ecosystem Services; Species Diversity and Ecosystem Functioning; Climate Change, Environmental Dynamics, and Vegetation Responses; and Biodiversity Monitoring, Population Trends, and Ecological Indicators.

The results show that biodiversity, conservation, diversity, species richness, management, climate change, ecosystem services, communities, and ecological dynamics occupy prominent positions within the selected literature. The network also demonstrates substantial connections among conservation management, ecosystem functioning, environmental change, and biodiversity monitoring. Qualitative interpretation of these patterns suggests that long-term plant conservation is treated in the literature as an interconnected ecological and management challenge requiring biodiversity protection, ecosystem restoration, adaptive responses to environmental change, sustained monitoring, and evidence-informed conservation planning.

This study contributes a structured account of the conceptual organization of the selected literature and identifies research areas that may require greater integration. The findings represent patterns of scholarly attention and keyword association rather than direct evidence of conservation effectiveness or causal relationships.
