【摘要】 铜川新区是一个新经济技术开发区，其行政边界与已有的行政边界不相对应，因而缺乏自然环境背景资料和与之相对应的社会经济统计资料。开展铜川新区的水环境管理，不能完全照搬已往城市水环境管理的模式，而应走一条新路。本次研究的目的是探讨新经济开发区的水环境管理模型构建与决策支持系统开发方法，为铜川新区的水环境管理提供决策支持。 本研究对BP神经网络应用于水质评价做了理论上的探讨，并基于MATLAB软件的神经网络工具箱实现了BP神经网络的铜川新区地表水和地下水质评价。结果表明，该方法克服了权重构造的人为性，信息利用更加充分，应用该方法进行水质评价，可以客观地反映水质状况，评价结果更为合理。 根据铜川新区现状，本研究将BP神经网络用于水质预测，实现了BP神经网络与BOD-DO、COD及综合水质模型的耦合。与一维水质数学模型相比，其结果具有更高的精度。 在系统开发方面，本研究提出一套新的系统集成方案，并首次实现了VB环境下MATLAB、LINGO、MapInfo和GeoBeans的高度集成，系统可以实现BP神经网络耦合水质评价模型、水质预测模型的计算，水污染控制规划方案的自动生成及求解，电子地图的制作和发布，环境信息的录入、输出、维护和查询功能。 铜川新区水环境管理决策支持系统的建立，对我国的水环境管理工作有一定的借鉴作用。更多还原

【Abstract】 Tongchuan New-district is a new economic and technological development zone, its boundary is different from it was, so there is a lack of the statistical information of environment and society. To manage its water environment in a new way, this paper does some research on the method of modeling and developing a Water Environmental Management Decision Support System in this zone, it will do some support for water environmental management in Tongchuan New-district.On the basis of a comprehensive exposition of the basic principles of the application of Back-Propagation network in water quality assessment, it assessed the surface water and groundwater quality in Tongchuan New-district with ANN toolbox of MATLAB platform. Case study reveals that this method can reflect the actual water quality reasonably because it can use information well and build the weight of Back-Propagation network impersonally.On the basis of a careful analysis of the environment, in addition, it established models of BOD-DO coupling, COD and comprehensive water quality simulation based on BP network. Case studies show a higher accuracy in the simulated results of BP network model over the one-dimensional model.Moreover, it brings forward new systems solutions in which approach developed an integrated software packages. This software integrates MATLAB, LINGO, Maplnfo and GeoBeans platform. It can assesse and simulate water quality based on BP network, put forward water pollution control planning measures, make and pubulish electronic maps, input, output and maintain environmental info.To sum up, the development of Tongchuan New-district Water Environmental Management Decision Support System will be used for reference to manage water environment in China.更多还原
