基于生态足迹的山东省水资源承载力研究

为研究山东省水资源生态承载力现状,缓解山东省用水压力,基于生态足迹的理论和方法,构建了水资源二级账户;同时,从城市发展的角度,选取了城市建设和社会经济中的相关指标,利用统计产品与服务解决方案(Statistical Product and Service Solutions,SPSS)软件,分别对山东省水资源生态足迹和生态承载力进行了相关性分析。分析结果表明:山东省水资源生态足迹和生态承载力均呈现出下降的趋势,水资源处于生态赤字状态;山东省水资源生态足迹受农业用水的影响最大,水资源生态承载力受降水的影响最大,城市设施水平对提高水资源生态承载力具有正面效应。因此,为了提高山东省的水资源生态承载力,提出了有针对性的措施,即应要改变农业灌溉方式,调节生产生活方式,并充分利用雨水资源,从而使得雨污资源化。

Research on water resources carrying capacity of Shandong Province based on ecological footprint

In order to study the current status of water resources ecological carrying capacity in Shandong Province and relieve the pressure of water use in Shandong Province, a secondary account of water resources based on ecological footprint is built. Relevant indicators of urban construction and social economy are selected from the perspective of urban development. SPSS is used to analyze the correlation between water footprint and ecological carrying capacity of Shandong Province. The results show that the ecological footprint and ecological carrying capacity of water resources in Shandong Province both show a downward trend. Water resources are in an ecological deficit state. The ecological footprint of water resources in Shandong Province is most affected by agricultural water use, and the ecological carrying capacity of water resources is most affected by precipitation, and the urban facilities has a positive effect on improving the ecological carrying capacity of water resources. Therefore, in order to improve the ecological carrying capacity of water resources in Shandong, it is necessary to change the mode of agricultural irrigation, transform the production and life style, and make full use of rainwater resources to make the rain and sewage become resources.
