西气东输走廊"资源-经济-环境"集成发展系统仿真研究

以西气东输管线气站为节点,建立了地下开发资源、地面拉动经济、空中减轻污染三个空间层次的集成仿真系统。仿真系统由流动模型、消费模型、环境模型和经济模型四部分组成。其中,流动模型是基础,它通过地下渗流模拟、地面管线流动模拟、空中污染物传质扩散模拟进行流量分析,再经过消费模型和环境模型,可得到污染物排放程度及空间分布。经济模型计算了由开发效益、环境效益和社会效益组合而成的综合经济效益,实现了西气东输走廊的资源、经济、环境的有机集成。最后,本文以西气东输终点的长江三角洲为例进行了计算,得出西气东输在资源、环境与经济上可取得的良好效果。

The Simulating System for Integrating Resource, Economy and Environment on the Line of "West Gas to East"

On the node point of the gas station along the line of west gas to east, this paper firstly creates the simulating system for integrating under-ground resource, ground consumption and above-ground environment. The system includes flow model, consumption model, environment model and economic model. Firstly, flow analysis is done by simulating flow through porous media, flowing through the pipe and consumption in city for gas. Secondly, in the environment model, the pollutant distribution in air is gotten. Finally, economic model integrates data from the above three models to compute total economic effect, so it realizes integrating resource, economy and environment. At the end of this paper, an example for the simulating system is given.
