平原地区农村供水工程的优化布局

Optimal Layout on Rural Water Supply in Plain Area

目前农村饮水工程因多方面因素影响,普遍存在着工程布局不合理现象。以安徽蒙城县为研究对象,从农村水厂的投资费用考虑,综合两方面因素对农村供水工程的布局进行优化,首先以供水经济距离为依据确定其供水范围,再在供水范围内建立以工程投资和运行费用最小为目标的线性规划模型。提出了在经济供水半径范围内的优化布局方案,即在乐土镇建水厂总费用最小。水厂的选址与用水量和供水距离有着密切的关系,在供水范围的中心区域建厂并不一定经济。

At present, there exist the unreasonable practices in the layout of rural water supply engineering. Taking Mengcheng County as a research object, the two-phase optimizations on the layout of rural water supply engineerings are analyzed here from the point of the investing cost of rural waterworks. The first phase optimization focuses on the determination of water supply area and humors of waterworks on the basis of economic distance, while in the second phase, the optimization for layout of waterworks is made by building a linear programming model of minimum water supply cost within the water supply area.
