本论文通过对浙江省农村人居环境现状及问题的分析，指出了导致浙江省农村人居环境建设整体水平较差的原因在于：城乡二元经济和社会结构的制约、村庄规划编制的滞后、管理体制和机构的不健全、农民意识的落后等。

The level of urbanization is positively correlated with the development of social and economy, and it is usually considered as an important token of economy development standard of the nation and region.The statistic in 2007 showed that the urbanization rate of Shan Dong province is 46.75%.The process of urbanization has been transformed from the rapid growth to the stable, and the quality has been improved entirely. But there still exist some problems, such as the urbanization level is below the industrialization level, the urban system is distempered and the development of small towns is backward.

城市化水平与社会经济的发展程度密切相关，城市化水平的高低可以用来衡量一个国家或者地区的经济发展状况。2007年山东省城市化水平达到46.75%，城市化进程正从高速增长期过渡到平稳增长期，城市化质量全面提升，但仍存在城市化水平仍落后于工业化水平，城市分布不均，体制不健全，小城镇发展落后等问题。
