This article examines the concept of regarding the agricultural ecosystem as an entirety, integrating the energy conversion and material cycle between various biocoenosiums of plants, animals and microorganisms and that between organisms and nonorganisms which run through the entire ecosystem, and composing scientifically the environment-ecosystem for the purpose of gaining the maximum biotic yield and the best efficiency in protection of the agricultural environment. It is indicated that ''methane-fermentation'' of agricultural organisms is an important link in fully utilizing matter and energy and reducing environmental pollution, and this will partly solve the problem of fuel shortage in rural areas as well. There is a need to find models of ecological farms which suit the realities of China. Even though ecological farms are a new concept in the agricultural sciences, some forms of ecological farms have long existed in traditional agricultural production of China. For example, the peasants in some flatland areas of southern China scrape sod from the borderdikes to bed down domestic animals, the mud-bearing sod is mixed with the excrement of livestock, and after pilling and rotting, the decomposed manure is applied as organic fertilizer in farmlands. A diagram of the production structure of a fishpond is presented.
