摘要
土地生态安全研究已引发广泛关注。通过分析土地生态安全评价主要文献,对国内土地生态安全评价发展历程、研究现状、研究难点进行梳理和总结,进而提出对土地生态安全评价研究的思考,以推动相关研究的完善和进一步发展。研究发现,国内现有成果主要从概念与内涵、指标和指标体系、研究方法、研究尺度、安全等级划分等角度对土地生态安全评价进行了探讨;已有成果主要是单一的静态时间序列土地生态安全评价,且多强调评价方法和结果,对土地生态安全评价自身缺陷和面临的难题关注不足,缺乏对未来发展趋势的预测和分析,也未能凸显土地生态安全评价的应用价值;当前研究难点和取得突破的关键在于土地生态安全内涵的界定、评价指标的选取和生态安全阈值的划分。未来土地生态安全评价应实现"评价-预警-调控"一体化发展。
The purpose of this paper is to improve the current research by the review of land ecological security development in China during the recent years,including its development history,current research issues,research difficulties and some thinking for this research field.Literature research and induction methods are used in this paper with the help of CNKI.The results show that:1)the current research contents of land ecological security evaluation mainly focus on conception,indicators,research methods,research scales and security state division;2)most of the current researches are static time-series evaluation without any prediction and analysis of the future state,besides,with emphases too much on the methods and results while with little attention on the defects and difficulties of land ecological security evaluation,and it makes the evaluation results useless to application;3)the research obstacles lie in three aspects:conception,indicators and threshold of land ecological security.Therefore,the definition of land ecological security,election of indicators of land ecological security evaluation,division of land ecological security threshold may be the key issue on the way of making breakthrough in the land ecological security evaluation.In the future,the research should take the"evaluation-early warning-regulation"into consideration as a whole.
