摘  要：
如何合理开发利用水资源,保护区域生态环境,实现人与自然的和谐发展,是当今世界所面临的共同问题。以陕北锦界生态工业园水资源系统为例,在分析系统结构的基础上,构建了水资源系统动力学模型,确定水技术进步因子、水资源循环利用率、污水处理投资率、万元产值年耗水量、日人均用水量为调控参数,进行仿真模拟。结果表明,当水技术进步因子由1提高到1·6,水资源循环利用率由0·45提高到0·85,污水处理投资率由0·18提高到0·25,万元产值年耗水量由236·8t·a-1降为175·4t·a-1,日人均用水量由0·18t·d-1降为0·12t·d-1时,园区工业总产值增长率5年可达到44·4%,水资源存量年均增幅为0·03%,水资源供需比为2·25,系统达到相对最优状态。

摘  要：
How to reasonably exploit and use water resources and protect regional eco-environment is an important issue in realizing the harmonious development between man and nature. Taking the water resources system in Jinjie ecological industrial park as an example and based on structure analysis, a system dynamics model was built, with water technology improvement factor (wtif), recycling ratio of water resources (rrwr), investment rate of sewage treatment (irst), water consumption per year per 10000 yuan GDP (wcy), and average water consumption per person per day (awcp) as the regulation parameters for simulation. The simulation results showed that when the wtif increased from 1 to 1.6, rrwr increased from 0.45 to 0.85, irst increased from 0.18 to 0.25, wcy decreased from 236.8 t·a-1 to 175.4 t·a-1, and awcp decreased from 0.18 t·d-1 to 0.12 t·d-1, the system would reach its optimal state, with the growth rate of gross industrial productivity rising to 44.4% in five years, mean annual growth rate of water resources storage being 0.03%, and supply/demand ratio of water resources being 2.25.
