摘    要:通过对农业生态系统的分析,建立了农业生态系统健康状况的评价指标、评价标准及综合评估模型,并运用层次分析法对甘肃省农业生态系统健康状况进行了综合评价。结果表明,除陇南、临夏及甘南农业生态系统处于较健康状况外,其它各地市均处于一般状况。各地区涉及到系统结构的自然环境因子均处于较低水平,其中尤以河西干旱区各地市结构各指数均处于较低值,其结构综合评价值均<2,而其它各生态区虽然结构指数存在差异,但差异不大,除中部的白银市以外,其它地区结构指数综合评价值均达到2以上,其中尤以陇南、甘南较高;从经济状况看,河西干旱区各地市均较处于其它生态区的地市高,而其它地区则相对较低。

关 键 词:甘肃省  农业生态系统  健康  评价

Abstract:Through the analysis of agro-ecosystem in Gansu Province,the evaluation indices,criteria,and comprehensive model for agro-ecosystem health were built,and AHP method was used to analyze the status of agro-ecosystem health in this Province.The results showed that the agro-ecosystem health status was relatively better in partial regions of Gansu Province,e.g.,Longnan,Linxia and Gannan,but at a lower level in other regions.The values of natural environmental factors related to the system structure of this Province were lower,especially in some districts of Hexi arid area whose system structure value was less than 2.Other regions except Baiyin district had a little difference in system structure value(higher than 2),and the values in Longnan and Gannan regions were relatively higher.From the viewpoint of economy,the economic indices values of Hexi arid area were higher than other regions in Gansu Province.
Keywords:Gansu Province  agro-ecosystem  health evaluation
