摘要

为分析比较全球公顷和国家公顷核算水资源生态足迹的异同，基于水资源生态足迹理论与方法，构建出"全球公顷"和"国家公顷"的山西省水资源生态足迹计算模型，对其2007—2018年水资源生态足迹进行了测算与比较分析。结果表明：（1）2种不同算法得出12年间山西省人均水资源生态足迹、人均水资源承载力、人均水资源生态赤字变化趋势相似，整体均呈上升趋势，但用国家公顷法得出的结果均大于用全球公顷法得出的同1年份的结果。（2）2种不同算法得出山西省2007—2018年万元GDP水资源生态足迹均呈下降趋势，说明12年间其水资源利用率在提高。（3）2种不同算法得出这12年间山西省水资源生态压力指数远>1，说明其水资源开发利用处于不安全状态。研究认为：（1）2种算法产生差异的主要原因在于采用的水资源均衡因子、水资源产量因子及区域水资源平均生产能力存在差异。国家公顷法比全球公顷法能更好地反映国家级以下空间尺度水资源开发利用态势。（2）需根据不同的研究目的，构建相应的计算模型进行水资源生态足迹的核算与分析，既有助于真实反映不同空间尺度上区域水资源开发利用态势，也有利于同级空间区域尺度上水资源生态足迹的比较。

Abstract

In order to compare and analyze the similarities and differences between global hectare and national hectare in water resources ecological footprint accounting

based on the theory and method of water resources ecological footprint

two calculation models of water resources ecological footprint in Shanxi Province with "global hectare" and "national hectare" were constructed

and the water resources ecological footprint of Shanxi Province in 2007—2018 were calculated. The results showed that: (1) The change trends of the per capita water resources ecological footprint

per capita water resources ecological carrying capacity and per capita water resources ecological deficit of Shanxi Province during the past 12 year obtained by the two models were similar

and the overall trends of all above indexes were upward. However

the results obtained by the national hectare method were all greater than the results obtained by the global hectare method in the same year. (2) Two different algorithms both showed that the water resources ecological footprint per 10 000-yuan GDP in Shanxi Province from 2007 to 2018 was declining

indicating that water resource utilization rate was improving in the past 12 years. (3) Two different methods showed that the ecological pressure index of water resources in Shanxi Province was far greater than one in the past 12 years

indicating that development and utilization of water resources was in an unsafe state. The research thought that: (1) The main reasons for the differences between the two algorithms were the differences in the water resources equivalence factor

water resources yield factor and the average production capacity of regional water resources. Compared with the global hectare method

the national hectare method could better reflect the development and utilization situation of water resources at the spatial scale below the national level. (2) According to different research purposes

it was necessary to construct the corresponding calculation models to calculate and analyze the water resources ecological footprint

which was not only conducive to better reflect the development and utilization situation of regional water resources on different spatial scales

but also was conducive to the comparison of the water resources ecological footprint on the same spatial and regional scale.
