Study on the Eco-Environmental Control Models of Small Basin in Arid Land, Western China

Adopting optimum control and scientific management for eco-environment is very important to protecting eco-environment against disruption and promoting the coordinated growth of soc-economic system and eco-environmental system and building a harmonious relationship between human behavior and natural world, especially in the arid land, western China. This paper, according to the eco-environmental characteristics of small basin in arid land, from the point of overall development of small basin, introduces the theory framework of eco- environmental control, and puts forward two main types of control models, that is, Dispose- Water-Model and Coordinate-Model. In the paper, a case study will be introduced too. The paper provides several good models and examples for eco-environmental control of small basin in arid land.
