以1985年、1995年、2004年和2013年四期Landsat TM/OLI影像和经济社会统计数据为主要数据来源 ,借用DPSIR模型框架从驱动力、压力、状态、影响、响应5个方面构建洪河农场土地生态安全评价指标体系.采用改进的 TOPSIS法对1985—2013年洪河农场土地生态安全演变进行研究 ,并对影响土地生态安全实现的障碍因素进行分析.研究结果表明 :研究期内洪河农场土地生态安全等级变化趋势呈"V"字形 ,其主要障碍因素从初期的响应系统 ,演变为研究期末的压力和状态系统 ;在土地开发利用导致生态环境压力、负面环境影响不断增大的同时 ,人类也对自身行为进行了的调整 ,采取对策进行对系统环境胁迫进行了积极的响应.

Based on the Landsat/TM image in 1985 ,1995 ,2004 ,2013 ,the alteration of land use survey and statistic yearbooks ,an index of land eco-security evaluation was established by using DPSIR model .The change of land eco-security in Honghe farm since 1985 to 2013 was studied by using TOPSIS model ,which is based on an entropy weighted index .Obstacle factors of land eco-security in different times were also analyzed in this paper .Results show that the change of land eco-security level in study area forms a 'V' shape ,and the major obstacle has changed from response system in early time to pressure and state system at present .This indicates that while the land exploration and utilization in Honghe farm puts pressure on the environment and brings some negative impacts ,human also change their activities and take positive measures as responses to stress on environment .
