临汾市水资源生态足迹的动态研究

Dynamics of Water Resources Ecological Footprint in Linfen City

运用水资源生态足迹模型和指数分解模型,研究临汾市2005年~2013年水资源利用的动态变化和影响因素.结果表明:临汾市水资源生态足迹总体呈波浪式上升趋势,水资源生态承载力整体变化比较稳定,年际间变化浮动小,水资源状况一直处于生态赤字;人均农业用水和工业用水足迹占总用水足迹的比例最大,但二者所占份额在逐年减少;结构指标对临汾市水资源生态足迹的变化影响不明显,经济指标和人口指标促进了水资源生态足迹的增长,技术指标在一定程度上抑制了临汾市水资源生态足迹的过快增长.

The water resources ecological footprint model and index decomposition model were used to analyze the dynamic change and influence factors of water resources utilization of Linfen. The results showed that the water ecological footprint of Linfen had a wavy upward trend, the ecological capacity showed a stable change and a small inter-annual variation. The water resources of Linfen had been in ecological deficit. The agricultural water consumption and industrial water consumption per capita took great proportion in the total ecological footprint of water consumption. However, both the share of water consumption was decreasing. The structural Indicators had a little influence on the change of water resources ecological footprint. Economic tors promoted the growth of water resources ecological footprint. Technical growth of water resources ecological footprint in some extent. indicators and demographic indicaindicators Inhibited the excessive
