摘　　要：首先运用综合评价法对宝鸡市近30年的城市化水平进行了测度,然后运用生态安全综合指数法对宝鸡市城市生态安全进行了定量评价,最后对两者进行了相关分析和多元回归分析。结果表明:最能体现城市化发展水平的"城市现代化水平"因子与城市生态安全之间存在着极强的正相关关系,城市现代化水平的发展是城市生态环境变好的主要影响因子。结合宝鸡市生态环境仍处于不安全状态、存在诸多问题的现状,提出了协调"加快城市化进程"和"良化城市生态环境"之间关系的三点建议。The urbanization level of Baoji City around 30 years was calculated by means of comprehensive assessment and then a quantitative evaluation for Baoji＇s eco -security was made by applying comprehensive exponential method. Finally, a related and regressive analysis was taken on some relevant factors of urbanization and urban eco - security. The result showed that there was a strong and close relationship between urban eco -security and urban modernization level which could well reflect urban development and urban resource stress. The direct reason leading to make urban eco - environment better was the urban modernization level. Three suggestions were put forward on coordinating the relationship between boosting urbanization process and making urban eco -environment better according to the problems which were existed in Baoji City.
