基于 ISM 的城市黑臭水体整治公众满意度影响因素

在我国城市大部分河道已演变为黑臭河道的背景下,进行黑臭水体整治、改善城市水环境成为一项重要任务。将公众满意程度和长效机制建设情况作为评判黑臭水体整治效果好坏的依据,已经成为一种趋势。以南京市鼓楼区6条黑臭河道整治的公众满意度测评数据为基础,通过单因素方差分析筛选出7个对公众满意度有显著影响的因素,利用解释结构模型(ISM)梳理7个因素间的内在关联,建立多层递阶结构模型,为政府进行黑臭水体整治提供参考依据。分析结果表明,水体的异味、异常颜色、洁净程度和公众对整治工程的了解程度是影响黑臭水体整治公众满意度的直接因素,受访者人员性质是其间接因素,沿河污水直排、沿岸垃圾堆放现象是其根本因素。
