基于生态足迹理论的宁夏水资源可持续利用研究

Study of Sustainable Utilization of Water Resources in Ningxia Based on Ecological Footprint Theory

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 theory of ecological footprint, by establishing the model of water resources ecological footprint and water resources carrying capacity, the IPAT model and related evaluation index is used to analyze the water resources ecological footprint, ecological carrying capacity and the situation of water resources sustainable utilization in Ningxia from 2004 to 2011. The results show that during the study period, the water resources ecological footprint per capita in Ningxia decreased generally; the water resources ecological carrying capacity per capita were stable; the water resources ecological deficit was relatively large; the utilization factor of water resources is raised increasingly, but the load of water resources ecological footprint increased gradually; the use of water resources in Ningxia is in an unsafe state.
