1、基于SD模型的城市水资源承载力动态仿真 摘要:为解决城市水资源供需矛盾,提高城市水资源的可持续承载能力和实现社会经济的可持续发展,利用系统动力学方法,建立了佳木斯市水资源承载力动态仿真模型,并结合区域资源利用和社会经济发展特点,设计了现状延续、治污开源、限采节流和综合协调4种提高水资源承载能力方案。方案仿真结果显示:现状延续、治污开源和限采节流三种方案在仿真年限内(2012年-2030年)未实现水资源供需平衡,水资源短缺问题仍将束缚佳木斯市工农业生产和社会经济发展;综合协调方案不仅在2015年保证了水资源供
2、需动态平衡,而且实现了社会经济的快速发展,是提高佳木斯市水资源承载能力的最佳方案。 关键词:水资源;承载力;系统动力学;动态仿真;佳木斯市 中图分类号:TV213;F323.2文献标志码:A文章编号:16721683(2015)05082705 Dynamicsimulationofurbanwaterresourcescarryingcapacitybasedonsystemdynamicmodel ―AcasestudyinJiamusiCity JIANGQiuxiang1,2,DONGHe1
