摘要
为研究中小城市水资源消耗情况和可持续利用状态,以江苏省宿迁市为例,利用水资源生态足迹分析方法对宿迁市2011-2017年水资源生态足迹、生态承载力的时空变化进行分析,结果表明:宿迁市水资源生态足迹呈先下降后上升的趋势,2015年最低,为42.84×10^6 hm^2,2017年最高,为50.44×10^6 hm^2;水资源生态承载力呈波动发展趋势与降水量成显著正相关关系;万元GDP水资源生态足迹呈逐步下降的趋势;泗洪县和泗阳县生态赤字现象较轻缓,工宿豫区和沭阳县较严重.建议合理利用水利工程,提高水资源的利用效率,优化地区用水结构.
In order to study the situation of water consumption and sustainable utilization in small and medium-sized cities,a case study was made of Suqian city of Jiangsu province,in which the spatio-temporal changesfrom 2011 to 2017 inthe ecological footprint and ecological capacity of water resources of this city were analyzed.The results showed that the ecological footprint of water resources in Suqian city first decreased and then increased,the lowest being in 2015(42.84×10^6 hm^2),and the highest in 2017(50.44×10^6 hm^2);that the ecological carrying capacity of water resources showed a fluctuating development trend and was in a significant positive correlation with precipitation;that the ecological footprint of water resources with a GDP of 10000 yuan was gradually decreasing;and that the ecological deficit was moderate in Sihong and Siyang counties,and more serious in Suyu district and Shuyang county.It is,therefore,proposed to make reasonable use of water conservancy projects,improve the utilization efficiency of water resources,and optimize the regional water consumption structure.
