| Abstract: | The coupling of agricultural economy system of Hexi corridor Oasis will bring about great potential economic benefits but it will also result in the ecological risks. In this paper the connotation of ecological risk is discussed and the main reasons for the production of ecological risks in the process of the systematic coupling are explored. The mathematical models on ecological risk assessment and risk decision are established and applied to the risk management and control of agricultural economic systems. |
