Through constructing a comprehensive warning index system of the unsafe conditions of cultivated land, the unsafe state of cultivated land of Chengdu City during 1999 -2010 was evaluated by adopting the analytic hierarchy process and entropy method to determine the index weight and applying the method of linear comprehensive evaluation. And then, the adjustment to the endangered cultivated land of Chengdu found that the ratio between cultivated land and soil, effective irrigation area, the area of farm with medium or lower productivity, the quantity of fertilization and pesticide in Unit of cultivated land are key factors to relieve the endangered situation.%构建了反映市域研究范围内耕地不安全状况的警情指标体系,采用层次分析法和熵值法确定指标权重,并运用线性加权综合法对1999 ～ 2010年成都市耕地资源系统的不安全运行情况进行警情评价.通过警情分析得出结论:耕地占土地面积比例、有效灌溉面积、中低产田面积、单位耕地化肥施用量、单位耕地农药施用量是短期内缓解警情的关键因子.
