山西省水资源生态足迹动态分析

Dynamic Analysis of Water Resources Ecological Footprint of Shanxi Province

利用水资源生态足迹模型分析了山西省2003-2012年水资源生态足迹动态,以明确其水资源可持续利用状况。结果显示:山西省人均水资源生态足迹总体呈现缓慢增长趋势,人均生态承载力变化基本平稳,水资源一直处于赤字状态;研究期间的万元GDP水资源生态足迹总体呈下降态势;水资源生态压力指数均大于1,表明了该区的水资源利用处于不安全状态。因此,山西省有必要采取一些有效措施调整产业结构,提高用水效率,改变水资源利用状况。

The water resources ecological footprint model was used to analyze water resources ecological footprint dynamic variations of Shanxi Province from 2003 to 2012,which can help characterize the sustainable utilization situation of water resources in this area.The results showed that：during the study period,the water resources ecological footprint per capita in Shanxi increased generally,and the water resources ecological carrying capacity per capita were stable.The water resources in recent 10 years were in an ecological deficit state.The water resources ecological footprint per 104 yuan GDP decreased annually.The water ecological pressure index was more than 1,which indicated that the use of water resources in Shanxi was in an unsafe state.Therefore,in order to change the utilization of water resources,some effective measures should be used in Shanxi Province,such as readjusting industrial structure,improving the water use efficiency.
