基于投影寻踪法的城市水生态文明建设评价

Evaluation of urban aquatic ecological civilization construction based on projection pursuit method

基于水生态文明城市建设的理念和要求,从水安全、水生态、水管理、水景观、水文化5个方面,构建了包含29项指标的城市水生态文明评价指标体系;综合考虑国内外的经济社会发展水平和区域特征,确立了理想、和谐、基本和谐、不和谐、极不和谐5个评价等级标准,建立了基于实数编码的加速遗传算法(real coded accelerating genetic algorithm,RAGA)的投影寻踪评价模型,并以安徽省马鞍山市为例,对其2012年的水生态文明建设情况进行等级评价。结果表明,马鞍山市2012年的水生态文明处于基本和谐的状态,与实际情况相符。

Based on the implications of and requirements for the construction of an urban aquatic ecological civilization,an evaluation index system composed of 29 indicators, which covers five aspects, including water security,aquatic ecology, water management, water landscape, and water cultures, was established. With full consideration of the economic and social development level and regional characteristics in China and abroad, five evaluation grades, including the ideal, harmonious, basically harmonious, inharmonious, and extremely inharmonious levels,were set up. The projection pursuit evaluation model based on the real coded accelerating genetic algorithm （RAGA） was built. This model was used to evaluate the level of aquatic ecological civilization construction in Maanshan City,in Anhui Province,in 2012. The results show that aquatic ecological civilization in the city in 2012 was at a basically harmonious level,which is consistent with reality.
