摘要
近年来在我国的生态农业建设实践中,生态位理论得到了广泛应用,并在应用中有了丰富和发展。孙鸿良等将生态位理论应用于农业生态系统。
Optimal patterns of eco-agricultural construction in central Hubei hilly region are studied with the application of niche theory. The research indicate that on hilly non-irrigated land, ecological environments are improved and niche elements of crop field are sufficiently used by introducing paulownia and constituting niche unit 'wheat-corn-bean' under it. In household ecosystems, the potential niches are more effectively used and its functions are improved after introducing methane-generating pit.
