湖南省2005年水足迹及其启示

水足迹是当前测度人类活动对水资源系统环境影响的最好指标。本文以我国南方水资源丰沛省份——湖南省为例，构建了水足迹账户，计算了2005年湖南总水足迹和人均水足迹以及水足迹相关评价指标。结果表明，湖南省水足迹在全国处于较低的水平，但通过对水足迹的结构、虚拟水流量以及发展趋势的分析，得出抓紧虚拟水和虚拟水战略影响研究，创新水资源管理观念、保障区域和国家水资源安全以及调整和优化农业结构，保障区域和国家粮食安全几点启示。

Water Footprint and its Thought in Hunan Province in 2005

Water footprint is the best index which estimates the environment impacts to water resource system by human activities. In this paper, Hunan province which is an rich -water region in south china, was taken as the research object. The water footprint account was construct and the total water footprint and the related measure index were counted. The results showed that the water footprint in Hunan province is relatively low in the nation. After the analysis about the structure of water footprint, flux of virtual water in the agricultural and animal production and the current of water footprint, it was thought that the influence study of virtual water strategy is important, the water resource management notion should be innovated and ensure regional and national water resource security, the agricultural structure should be adjusted to ensure regional and national food security.
