摘    要:本文采用文献资料法和对比法从耕地生态安全研究阶段、概念、特征、驱动因素、评价尺度、评价方法与技术、评价指标体系、模拟预测、保护措施等方面对国内外耕地生态安全评价的主要研究成果进行系统的总结、对比和分析。研究表明:耕地生态安全研究经历了区域生态安全格局构建的初始研究阶段、生态环境评价研究的发展研究阶段、耕地生态安全评价研究的崭新阶段,并逐渐成为研究的难点与热点;耕地生态安全概念初步建立,耕地生态安全评价刚刚起步,中尺度综合研究与科学合理的评价指标体系相对缺乏,现有研究多侧重于现状分析,缺乏动态变化和模拟研究,难以从整体上把握区域耕地生态安全时空演变规律与机理。因此,今后开展耕地生态安全评价与模拟研究十分迫切,对于完善耕地资源安全研究具有重要的理论意义,可为控制未来耕地规模减少以及保护耕地生态环境,编制土地利用总体规划提供科学依据。

关 键 词:耕地生态安全  概念  评价指标体系  评价尺度  评价方法  模拟预测  时空演变

Abstract:The research progresses on studies phases, concept, characteristics, driving factors of ecological security of cultivated land were summarized in the paper. The paper also systematically discussed the evaluation scale, method and technology, index system, as well as simulation and forecast, protection measures of ecological security of cultivated land through literatures review. The main previous research results were also compared and analyzed. The ecological security of cultivated land had experienced the primary stage of construction, the development stage of evaluation, the new stage of evaluation, and it had been becoming an important and hot topic in the corresponding research fields. The concept of ecological security of cultivated land had been set up, and cultivated land ecological security evaluation just started. The existing researches were mainly focused on analysis of current situation of cultivated land ecological security, the comprehensive researches on mesoscale, scientific and rational evaluation index system, dynamic change and simulation studies were still relatively lack. Consequently, it is difficult to comprehensively understand the spatio-temporal evolution and mechanism of cultivated land ecological security. As a conclusion, the future researches should focus on the integrated evaluation and simulation of cultivated land ecological security with spatial-temporal changing characteristic from multi-scales. The results would play a great significance role on the theory of cultivated land ecological security research. They also would benefit cultivated land protection and area reduction control, and design of land utilization plan.
Keywords:Cultivated land ecological security  Concept  Evaluation index system  Evaluation scale  Evaluation method  Model simulation  Spatial-temporal evolution
