中文摘要：
以1998-2009年有关统计数据为依据,从人口、经济、生活方式、地域景观四个方面,构建渭南市城市化水平综合评价指标体系,应用主成分分析法对渭南市城市化水平进行综合测度;同时引入生态环境压力指数对渭南市生态环境压力进行定量评价,并对它们进行了相关分析和回归分析。结果表明：（1）1998-2009年渭南市城市化综合水平持续提高;（2）生态环境压力与城市化综合水平之间存在高度正相关关系。（3）生态环境压力与城市化水平关系回归方程为y=30.105＋37.988x,在a=0.05信度水平通过检验,实现了对二者之间的定量描述,以期为渭南市未来城市发展提供科学依据。
英文摘要：
Take Weinan City as an example,we established a comprehensive evaluation index system of Weinan from four aspects： population,economy,life-style and regional landscape based on the PCA method to estimate the comprehensive level of urbanization and ecological environmental pressure of the city,and analyzed the relation between the city＇s urbanized level and ecological environmental pressure.The results were as follows.Firstly,the weinan＇s urbanized level continued improving from 1998 to 2009.Secondly,it was a high positive correlation between urban ecological environmental pressure index and the comprehensive level of the urbanization and the four urbanization principle components.Thirdly,the relation between urbanization level and urban ecological environmental pressure＇s regression equation was y=30.105＋37.988x,the test passed at reliability level α=0.05.Which Realized the quantitative description between them,so we hope this paper can provide a scientific basis to Weinan in the future＇s development.
