This paper is to introduce a numerical simulated model on the environment early-warning system of the oil-gas field aided by GIS by analyzing the characteristic features of oil leakage.As is well-known,oil leakage is detrimental both to the environment and to human health.In order to reduce the loss of oil leakage,we have established an environment early-warning system in the oil-gas fields,on the basis of GIS and numerical model.Specifically speaking,the system developed by us is made up of an air pollution simulation model,the surface water simulation model and the groundwater simulation. Our system is aimed to perform three functions,that is,management and control of the environment-monitoring data,the real-time monitor warning and pollution simulation and the instanlogtaneous emergency response.In order to take into full account the system developed,we have made a detailed introduction of the designing methods,the basic functions and the numerical simulation model on how for the system to be applied on the working spot.The primary practical application of the system shows that this system can be successfully used to perform its above-said functions.It can be said that this system can help the technicians and its other users working in the oil and gas field to perform their duties in environmental monitoring and surveillance and help to make decisions in the oil-gas field construction and production,in addition to the routine activities for environmental risk warning and environment protection.
