为提供农业结构战略性调整和区域水资源管理的有效措施,以虚拟水计算方法为基础,对2000年湖南郴州市的农产品虚拟水进行了量化分析,并对区域农产品的战略性调整和区域水资源有效配置决策思路进行了探讨.结果表明,每生产1 kg大米,需要耗费至少773.8 kg的水资源;生产1 kg植物油耗费的水量为8 286.3 kg;生产1 kg蔬菜的水量最少,但至少也需要1 49.9 kg的水量.郴州市的农村居民年农产品虚拟水数量远高于城镇居民的,其中大米所消费的虚拟水量就分别达到147.166 m3和41.744 m3.在不降低人均水资源消费需求和不降低人类生活质量的情况下,水资源较丰富的地区可通过农产品虚拟水贸易方式,更好地发挥区域性...

Agriculture is the most important section of making use of water resources,whose content in agricultural products is higher. The water used in the production process of an agricultural or industrial product is called the virtual water contained in the product. In this paper,based on calculation methods of the virtual water,quantitative analysis on virtual water of agricultural products is studied and some suggestions have been put forward on how to adjust the structure of agricultural products and utilize the water advantages in Chenzhou in of Hunan 2000.Results show that it may consume 773.8 ...
