摘　　要：通过对分形理论和给水管网特点的研究,建立了一种新的定量描述给水管网空间分布状态的评价指标--管网覆盖度和管网覆盖深度。采用盒计数法计算给水管网规划布置的分形维数,将给水管网的规划布置由定性分析改为定量分析,从而为给水管网的定线和布局做出合理的指导,使给水管网的平面布置更加科学可靠。Based on the fractional theory and the characteristics of water distribution network,a new water distribution evaluation indexes-network coverage and network covering depth was established to quantitatively describe the spatial distribution system.Box-counting algorithm method was used to calculate the fractal dimension for the water distribution planning layout.This method improved the layout of water supply network from qualitative analysis to quantitative analysis,it can also reasonablely guide the alignment and layout of the water network,so that the water supply network can be more scientific and reliable.
