摘要
黄土丘陵区是一个特定的生态环境脆弱区,对这个地区的生态安全评价显的尤为重要。采用层次分析法研究建立了黄土丘陵区农业生态安全综合评价指标体系,并以延安市宝塔区和安塞县为典型区,利用数学模型计算出这2个区域的农业生态安全指数,以此表征黄土丘陵区的农业生态安全现状,并针对此区域的生态安全问题提出相关建议。
The loess hilly region is a specific and fragile zone of ecological environment. An evaluation of ecological security is particularlyimportant to the agricultural development in the region. By using hierarchical analysis process, an indicator system is set up to assess the agricultural ecological security of typical county in the region. By taking Baota District in Yan＇an City and Ansai County for an example, a mathematical model is used to calculate the index of agricultural ecological security in the two places and then the index is used to characterize agricultural ecological security status in the loess hilly region. Finally, in view of the ecological safety problems of this region, some recommendations are given.
