摘　　要：从生态安全视角,针对东北地区耕地利用过程中的耕地质量问题,依据压力、状态及响应的理念,构建东北地区耕地生态安全评价模型,分析1990—2020年耕地生态安全的时空演变格局,探讨其影响机制。结果表明:(1)耕地核密度分异明显,集聚分布特征显著,表现为“西密东疏”的空间分布格局。(2)耕地状态、响应在波动中缓慢上升,而耕地压力则在波动中下降。(3)自然资源条件的影响力呈现下降趋势,而地理区位条件、社会经济因素及区域政策等因素呈上升趋势。最后,针对当前中国耕地生态安全问题,建议控制耕地污染、加大土地整治及完善耕地保护制度。From the perspective of ecological security,aiming at the problems of cultivated land quality in the process of using cultivated land in northeast China,based on the concepts of pressure,state and response,an evaluation model of cultivated land ecological security in Northeast China was constructed.The spatio-temporal evolution pattern of cultivated land ecological security was analyzed from 1990 to 2020,and its influence mechanism was discussed.The results showed that:(1)There were obvious differences in cultivated land kernel density and significant agglomeration distribution characteristics,which showed the spatial distribution pattern of"west dense and east sparse".(2)The state and response of cultivated land increased slowly,while the pressure of cultivated land decreased.(3)The influence of natural resources conditions showed a downward trend,while that of geographical location conditions,social and economic factors and regional policies showed an upward trend.In view of the current ecological security of cultivated land in China,this paper suggests that the pollution of cultivated land should be controlled,land consolidation should be strengthened and the protection system of cultivated land should be improved.
