采用定额法核算白洋淀流域2003年、2007年和2011年的水足迹,重点分析白洋淀流域内农业、工业和第三产业的水足迹结构.结果表明,白洋淀流域的虚拟水足迹从2003年的83畅86亿m增加到2007年的95畅87亿m 3,2011年的108畅21亿m 3.从消费比例来看,农业用水所占比例最大,平均值达到69%;第二产业用水占24%左右,第三产业用水占7%左右.提出解决白洋淀流域不同类型湿地生态需水的策略:调整流域种植结构,减少高污染、高耗水部门,提高农业灌溉效率和水资源重复利用率等,每年可节约5畅95亿m 3的水量,可以保障白羊淀流域湿地生态系统基本的生态需水.3

@@@@The quota method was used to calculate the water footprints in the Baiyangdian Basin in 2003, 2007, and 2011.The structures of water footprints of agriculture , industry, and tertiary industry were analyzed .The results show that the virtual water footprints in the Baiyangdian Basin increased from 83.86 ×10 8 m 3 in 2003 to 95.87×10 8 m 3 in 2007 and 108.21×10 8 m 3 in 2011.Agricultural water use accounted for the largest proportion (about 69% on average ), and secondary and tertiary industrial water use accounted for 24% and 7%, respectively, of the total water use.Several strategies were put forward for satisfying eco-environmental flow requirements of various types of wetlands in the Baiyangdian Basin .These strategies include the adjustment of planting structure, the reduction of highly water-consuming and water-polluted industries, and the improvement of agricultural irrigation efficiency and the water reuse ratio .Through implementation of the strategies, about 5.95× 108 m 3 of water can be saved per year, which meets the basic eco-environmental flow requirements of wetland ecosystems in the basin.
