[Research directions of agroecosystem health in the early 21st century].
Agroecosystem health refers to the state of an agroecosystem where it is free from 'distress syndrome' and to cope with stress, or capability to produce agricultural products in a sustainable way. At present, the research of agroecosystem health focuses on assessment methods, soil and water quality, human health, ecologically based pest management, integrated weed management, ecopathology, nematode communities, transgenic crops, agricultural input policy, landscape ecology and green food development. Firstly, the present state of agroecosystem health research was described; then a case study of agroecosystem health, biological indicators of soil health, was introduced; finally, the research directions of agroecosystem health were put forward. This paper could provide a basis for ensuring agricultural product security and increasing human health.
