【Abstract】 From 1985 to 1990, the experiments of compound ecological engineering in reservoir inlet were carried ont in Fushui Reservoir, South—eastern Hubei Province. There are 129 inlets which were separated from the reservoir by dam. This paper dealt with the basic structure types of the ecological engineering and analyzed their efficiency in the light of the experimental practices in Fushui Reservoir. According to the biogeographic characteristics and resources conditions of the different inlets the various ecological strucrtures were laid out. Generally, they can be divided into 3 types: (1) Multilayer vertiacl biological structure, (2) Multistage material cycle in the ecosystem, (3) Multicomponent ecological system.更多还原
