摘要
从提出背景、概念内涵、本质特性以及实践内容来看，持续农业具有鲜明的生态内涵，研究离不开生态学的指导；从系统主体、出发点（基本假定）、尺度、过程、动态来看，区域持续农业在更大程度上属于景观生态学的研究范畴。因此景观生态学可作为区域持续农业的理论基础，而作为景观生态学应用方向的景观生态规划便可作为实现区域持续农业的空间途径。最后，文章以中国北方农牧过渡带与冀北山地的景观利用方向进行案例实践。
The concept of sustainable development has been universally accepted in academic circles, scientific and technological cinrcles and policymaking bodies. Sustainable agriculture is an important objective in sustainable development. Agricultural sustainability can be judged from three aspects, i. e. ecological, economic and social sustainabilities. Among which ecological sustainability is the base of agricultural sustainability, and economic and social sustainabilities are dependent on ecological sustainability. Therefore, ecological sustainability can be as one of the basic targets of sustainable agriculture.. Sustainable agriculture (SA ) possesses the clear ecological features because of its background of generation, concept, attribute and practice, therefore the studies on SA need the guidance of ecology. In ecology, regional sustainable agriculture should belong to the field of landscape ecology (LE ) due to its emphasis, assumption, scale, process and dynamics in ecosystem. Landscape ecological planning (LEP) is the application area of LE. Therefore LEP can be taken as the spatial approach to realize RSA. Two cases are provided to realize this approach.
