景观生态学属于宏观尺度生态空间研究范畴，它的理论核心集中表现为空间异质性和生态整体性两方面。持续性，包括农业景观持续性的最终目标在于人类与其环境的整体协调，即广义的人类生态整体性。持续性研究涉及广阔的地域空间，其目标的实现则有赖于空间途径。这一认识是将景观生态学应用于持续农业发展的理论出发点。

The theoretical focuses of emerging Landscape Ecology are spatial hete rogeneity and ecological holism. The ultimate aim of agrolandscape sustainability is the harmonious relation between human and its environment, that is, the human ecological holism. The study on agrolandscape sustainability deals with an extensive area, and the realization of agrolandscape sustainability must depend on a spatial approach. Therefore, Landscape Ecology could be taken as the theoretical foundation of agrolandscape planning and design.
