摘要
运用层次分析法,构建了东营市土地生态安全评价的指标体系,对东营市进行评价。研究结果显示,2003～2008年,东营市生态安全指数由等级Ⅲ提高到等级Ⅳ,即由土地生态安全的一般状态改善到良好状态;次一级的土地生态安全指数显示,东营市土地自然安全指数和土地社会经济安全指数提高较快,而土地环境生态安全指数提高较慢。
By means of AHP, the study worked out an index system of land ecological security evaluation to evaluate Dongying City. The result showed that the index of Dongying City went up from stand m to stand IV during the study period （ from 2003 to 2008 ）, which means that the land ecological security was improved from a state of se-se to a state of much better. And as to the three sub-hierarchy indexes, the indexes of land na- ture security and land social security went up faster than that of land environmental ecological security.
