摘　　要：土地资源生态安全评价不仅关注土地资源的数量与质量,还考虑其生态系统的稳定性与可持续性,对于维护区域生态安全、促进经济社会可持续发展具有重要意义。通过科学评价与合理规划,可推动土地资源可持续利用与生态环境健康发展。根据PSR(压力-状态-响应)评价模型选择15个影响因素,系统评价2018—2022年伊春市的土地生态安全状况,对伊春市土地生态安全进行分级。研究表明,2018—2020年伊春市的土地生态安全等级良好,2021—2022年其土地生态安全分级为安全,伊春市土地生态安全系统整体处于良性状态,且具有上升趋势。Land resource ecological security evaluation not only focuses on the quantity and quality of land resources,but also considers the stability and sustainability of its ecosystem,which is of great significance for maintaining regional ecological security and promoting sustainable development.Through scientific evaluation and rational planning,sustainable utilization of land resources and healthy development of ecological environment can be promoted.According to the Pressure-State-Response(PSR)evaluation model,15 influencing factors are selected to systematically evaluate the land ecological security status of Yichun City from 2018 to 2022.The land ecological security of Yichun City is classified.It is shown that the land ecological security classification of Yichun City from 2018 to 2020 is good,while from 2021 to 2022 it is safe.The overall land ecological security system of Yichun City is in a benign state,and has an upward trend.
