摘　　要：为综合评价城市人水和谐度,从水资源、生态、社会、经济4个方面建立了评价指标体系,采用基于Spass软件的主成分分析法构建了城市人水和谐度评价模型,对北京市2011-2016年的城市人水和谐度做出评价,并与投影寻踪法计算结果进行比较。计算结果表明:北京市城市人水和谐度呈现总体上升的趋势;通过主成分分析,表明北京市应重点从社会、经济方面提高城市人水和谐度,与北京市实际情况相符;该评价模型具有合理性和可行性。In order to synthetically evaluate the harmonious degree of human and water in urban areas,an evaluation index system was established from 4 aspects of water resources,ecology,society and economy.The evaluation model of urban human-water harmony degree was constructed by using principal component analysis based on Spass software,and the human-water harmony degree of Beijing in 2011-2016 was evaluated and compared with the projection pursuit method. The results show that human-water harmony degree of Beijng demonstrates an overall upward trend. By principal component analysis,this indicates that Beijing should focus on improving the urban human-water harmony from the social and economic aspects,which is consistent with the actual situation in Beijing. The evaluation model is reasonable and feasible.
