摘要
在综述了前人对农牧交错带的认识后，给出中国北方农牧交错带的概念和区域界线；认为土地利用结构的农牧交错性是地带性与非地带性双重影响的结果，其空间格局有６种区域组合类型；随着人口负荷的加大，调整土地利用结构是保证这一地带生态安全与粮食安全的基本出路。
This paper reviews predecessors' understanding on ecotone between agriculture and animal husbandry,introduces the concept applied in northern China and regional boundaries of the ecotone,and points out that zonal and azonal geographic factors are accountable for the interlocking characteristics of farming and animal husbandry in landuse patterns.Six spatial landuse patterns are identified in the ecotone.The paper suggests that with the increase of population supporting capacity,regulation of landsue spatial patterns is an essential way to ensure future ecological and food security of the ecotone.
