摘要
农业生态安全是农业可持续发展的基础与核心,对于国家的安全和稳定意义重大.在建立指标体系的基础上,利用综合评价法对宁夏1997—2010年农业生态安全进行评价,结果显示:压力指数在经历前期波动后,呈现整体增加的态势,状态和响应指数的增加趋势则更为明显,综合指数的变化规律与压力指数相似,从1997年的0.414 4增加为2010年的0.659 4,今后应从减少农业环境污染、挖掘农业节水潜力和加大农业资金投入等方面提高宁夏农业生态安全水平.
Agricultural ecological security（AES） is the foundation and core of agricultural sustainable development. It is very important for national security and stability. Evaluation index system was built and the level of AES in 1997--2010 was assessed by using of comprehensive evaluation method. Result shows： After an early fluctuation, pressure index raised roughly. The increase trend of state and respond index are more obvious. The changing regularity of comprehensive evaluation index is similar to pressure index. It increased from 0. 4144 to 0. 6594 from 1997 to 2010. In the future, some measures should be taken to improve AES, such as decreasing pollution, realizing agricultural water-saving potential and increasing capital investment in agriculture.
