【摘要】:近年來,國際上關(guān)于生態(tài)安全研究的文獻(xiàn)大量涌現(xiàn)。隨著全球變化和人類活動影響加劇,生態(tài)安全研究正發(fā)生著深刻變化,呈現(xiàn)出多目標(biāo)、多層次、多學(xué)科交叉綜合的復(fù)雜特點,研究主題日益豐富,但模糊性和爭議性問題一直存在,對已有文獻(xiàn)成果進(jìn)行系統(tǒng)分析非常有必要。利用引文網(wǎng)絡(luò)分析可視化工具CitespaceⅡ,通過繪制科學(xué)知識圖譜,以定量與定性相結(jié)合的可視化文獻(xiàn)綜述研究方法,對各國學(xué)者發(fā)表的生態(tài)安全研究成果進(jìn)行系統(tǒng)分析梳理,展示了研究主題的演進(jìn)軌跡和發(fā)展趨勢,總結(jié)了其發(fā)展變化的內(nèi)在原因。研究表明:生態(tài)安全的研究主題可分為持續(xù)性和階段性兩類,主題演化軌跡符合Gartner光環(huán)曲線理論,人類文明發(fā)展階段、國際政治經(jīng)濟(jì)格局、學(xué)科研究水平是決定生態(tài)安全研究階段和主題演變的主要因素,該領(lǐng)域經(jīng)歷了問題提出與概念形成期、奠基拓展期、縱深發(fā)展期3個階段,各階段都有一些關(guān)鍵文獻(xiàn)出現(xiàn),這些引領(lǐng)學(xué)科發(fā)展的經(jīng)典文獻(xiàn)以自然科學(xué)研究為主;全球化、生物多樣性、生態(tài)農(nóng)業(yè)與農(nóng)業(yè)集約化、恢復(fù)力、脆弱性是當(dāng)前生態(tài)安全領(lǐng)域的研究熱點;保障人類生存發(fā)展基本需要和人對環(huán)境變化的適應(yīng)與響應(yīng)將是21世紀(jì)生態(tài)安全研究的主要方向。
[Abstract]:In recent years, a large number of international studies on ecological security have emerged. With the increasing influence of global change and human activities, the study of ecological security is undergoing profound changes, showing the complex characteristics of multi-objective, multi-level and multi-disciplinary integration, and the research topics are increasingly rich. But fuzziness and controversy exist all the time, so it is necessary to analyze the existing literature systematically. With the aid of Citespace 鈪,
