摘要：

Sustainable agriculture has emerged as the most agreed-upon term to synthesize a variety of concepts and perspectives associated with agricultural practices that differ, from those of conventional production. Definitions of sustainable agriculture contain three equally important components: environmental quality and ecological soundness, plant and animal productivity, and socioeconomic viability. The Agroecosystem component of the Environmental Monitoring and Assessment Program is developing a systems-level approach to the long-term monitoring of agroecosystem sustainability. Measurements will be made for a suite of indicators at sites selected from a probability sampling frame. Associations between indicator values over time will be used to assess agroecosystem condition and status on a regional and/or national scale. One or more measures of sustainability will be developed by organizing indicators and assessment end-points into a framework based upon the three components of sustainable agriculture.
