| 摘 要： | 以宁夏红寺堡移民区为例，构建了其农业可持续发展的生态安全评价指标体系，采用均方差确定了评价指标的权重，对研究区1999、2000、2001、2002、2003、2004、2005、2006年8年的农业生态安全进行了评价，从评价结果可以看出，红寺堡移民区农业生态安全总体呈下降态势，安全等级处于Ⅲ一Ⅳ级，安全状态从敏感态下降到风险态．2004年是研究区农业生态安全变化的转折点，从2004年起，农业生态安全有所回升．在分析变化原因的基础上，提出农业可持续发展的生态安全建设对策．

| Abstract: | As a case study of Hongsibu,NingXia Province,in this paper we established the indicator system of ecological security on agricultural sustainable development,determined the weight of the indicator by the method of mean square deviation,and evaluated ecological security on agriculture development among 1999~2006 by using the model of ecological security.The result showed that the ecological security of agriculture had being decreased during the past 8 years,the grade of ecological security of Hongsibu of the... |
