The Ecological Environment Evolves Systemsimulation Research About Xinjiang Ebinur Lake Basin

The water resources is one of the most important resource in natural, which is basic physical conditions that relates the human survival and the social development; also the important guarantee to realizes the economic society sustainable development. The water resources is the key factor for the development of Oasis in the Xinjiang Ebinur Lake ecological.According to the material demonstrated that the Ebinur Lake level of the lake area from the 1940s's 1200km2, withered to 542km2 at present. The gale curls up the sand salt 4,800,000 tons every year from the Ebinur Lake exposed Lake Bottom, all this seriously influence local resident's life. These attributing to the excessive development and the unreasonable use's water resourcesThis paper applies the systems dynamics method in the research of evolves in the Ebinur Lake basin ecological environment, Taking systems dynamics's theory, the method, the model as frames, Synthesis using measurement geography, sustainable development, water and soil resources supporting capacity and so on many kinds of theories and method,Using newest edition SD model software Vensim,Establishes the system dynamic simulation model about the Ebinur Lake basin water resources supplying and demanding situation .The model divided into the organic connections in together three constituent: Population subsystem, resources subsystem and environment subsystem.。Through to the Ebinur Lake basin population,the resources,the environment these three system's dynamic simulation model carrie on the simulation and the predict, put forward the countermeasure proposal for the Ebinur Lake basin's ecological environment's restoration.
