Establishment of Environmental Risk Assessment Model in Gansu Basin

The potential environmental risks in Gansu basin are prominent. There are many enterprises with environmental risks distributing in the main trunks and tributaries of the Yellow River, Yangtze River and inland rivers in Gansu Province. Transportation routes of dangerous chemicals paralleling or acrossing rivers are common,which constitute the environmental layout and overlapping risks in Gansu basin. It is of great practical significance to understand the current situation of regional risk and put for-ward risk control measures scientifically by environmental risks assessment in the basin.Based on the theory of environmental risk system, this paper puts forward a watershed environmental risk assessment model which is suitable for the actual characteristics of environmental risk in Gansu Province from two aspects of basin basic risk level and mobile source risk level, aiming at effectively managing and controlling the environmental risk of watershed and establishing and perfecting the risk prevention and control system for the ecological environment management departments.
