基于生态足迹理论,通过构建水资源生态足迹模型与水资源生态承载力模型,并用相关评价指标及IPAT模型分析了宁夏回族自治区2004~2011年水资源生态足迹、承载力及水资源可持续利用状况。结果表明,研究期间宁夏人均水资源生态足迹呈下降趋势,人均水资源生态承载力较稳定,水资源生态赤字较大,水资源利用率不断提高,但水资源生态足迹负荷有加重趋势;宁夏水资源利用处于不安全状态。
Based on the ecological footprint theory, the ecological footprint of water resources and the sustainable utilization of water resources in Ningxia Hui Autonomous Region from 2004 to 2011 were analyzed by constructing a model of ecological footprint of water resources and the ecological carrying capacity of water resources, and using related evaluation indexes and IPAT models . The results showed that the per capita ecological footprint of Ningxia decreased during the study period, the ecological carrying capacity of per capita water resources was relatively stable, the ecological deficit of water resources was larger, and the utilization rate of water resources was continuously increased, but the ecological footprint of water resources tended to increase. Resource utilization is in an unsafe condition.
