天津市民水资源保护意识定量评价

Quantitative evaluation on public water resource protection consciousness in Tianjin

水资源是维持人类生存、经济发展与社会进步的重要物质。但随着人口增长和社会经济的快速发展,水资源短缺和水污染问题日益严重。加强水资源保护意识宣传,提高市民节水意识,是实现水资源可持续利用的重要途径。文中基于系统观念,建立了一套综合评估市民水资源保护意识的指标体系,针对天津市民开展实证研究。选用层次分析法确定指标权重,通过模糊综合评价模型进行定量评价,采用相关分析辨识主要影响因子。结果表明:天津市民水资源保护意识总体一般,水资源保护意识强、中、弱的市民比例分别为50.96%、37.77%和10.92%;不同特征人群水资源保护意识存在差异;基于ArcGIS的空间分析表明天津市民水资源保护意识水平存在"东南高西北低、内高外低"的分布规律。
