摘　　要：以"五位一体"生态果园模式为研究对象,从结构、功能和评价指标3个方面分析"五位一体"生态果园模式与"三位一体"和"四位一体"沼气生态农业模式的差异特征,构建"五位一体"生态果园模式区域适宜性评价模型.选择中国西北地区100多个站点进行"五位一体"生态果园模式区域适宜性评价.结果表明,西北地区"五位一体"生态果园模式发展适宜区包括新疆塔里木盆地和陕西中部;次适宜区包括陕西南部、新疆南部(除塔里木盆地)、甘肃东部和新疆伊犁地区;非适宜区包括陕西北部、宁夏大部、青海大部和新疆北部.Taking ＂five-in-one＂ecological orchard model as the object of study,this article analyzes discriminative features of ＂five-in-one＂ecological orchard model and ＂three-in-one＂and ＂four-in-one＂methane ecological agricultural mode from three aspects to build regional suitability assessment model of＂five-in-one＂ecological model.More than 100 sites in northwestern China were chosen for regional suitability evaluation of＂five-in-one＂ecological orchard model.The result shows that the suitable region of northwestern ＂five-in-one＂ecological orchard model includes central region of Shaanxi province and Tarim Basin in Xinjiang;Subordinate suitable area includes south of Shaanxi province,southern Xinjiang except for Tarim Basin,eastern Gansu,and Yili of Xinjiang.Unsuitable area：southern Shaanxi,most part of Ningxia and Qinghai,and northern Xinjiang.

关 键 词：西北地区 五位一体 生态果园模式 区域适宜性评价
