我国沿海地区生态城市建设评价

本文从城市生态系统的结构、功能和协调度三个方面构建了生态城市的指标体系，提出了生态城市的评价方法，并选取沿海16个城市进行城市生态化建设的综合评价与比较分析。采用适合生态城市建设的数学模型对这些城市的复合生态系统进行定量分析，其中指标涉及人口指标、生态环境指标、经济指标与社会指标4个方面，构建3个一级指标，10个二级指标，25个三级指标。得出了16个沿海城市生态化水平的比较结果，因之深圳在城市结构、城市功能方面明显高于其它城市，其生态化综合水平位居首位，其值超过标准值达到了1.19，营口市在工业废水达标率、环境噪声达标率、人均生活用水、人均国民生产总值与失业率方面得分最低是导致其生态化综合水平最低的主要原因。16市在城市环境方面得分普遍较低，表明大气质量与环境噪声是限制这些城市生态建设的主要因素。

Assessment for the Level of Ecological City in Inshore Regions in China

This paper designs index system including structure, function and harmonious degree for assessing level of ecological city in inshore regions in China, and brings forward a methodology of assessment. 16 cities assessed and compared are Dalian, Qinghuangdao,Yingkou, Jinzhou, Qingdao, Rizhao, Lianyungang,Shanghai,Ningbo,Hangzhou, Shaoxing, Zhuhai, Shenzhen, Dongguan, Zhongshan, and Guangzhou. Quantificational analysis of degree of ecological cities is through mathematics model involving population as well as ecological, environmental, economical and social indexes. In the assessment system, there are three first -level indexes, ten second-level indexes and twenty five-third level indexes. The results show that the sequence of ecological level is Shenzhen > Zhuhai > Ningbo> Dongguan> Guangzhou> Shanghai> Dalian> Hangzhou> Qinghuangdao> Zhongshan> Shaoxing> Qingdao> Liangyunguang> Jinzhou> Rizhao> Yingkou. In the 16 cities, the city of highest level is Shenzhen whose value is 1.19, and the city of lowest level is Yingkou whose value is 0.34. The restraining factors that affect the level of ecological city are analyzed too, and results show that atmosphere condition and noise are main factors impacting the advancing of level of ecological city widely , so the result of research can become the basis of the constructing of the ecological city.
