城市化带来的问题
城市化是指一个地区的人口在城镇和城市相对集中的过程。城市化的程度是衡量一个国家和地区经济、社会、文化、科技水平的重要标志，也是衡量国家和地区社会组织程度和管理水平的重要标志。
由于城市化进程的复杂性、艰巨性和特殊性，在此过程中也面临着许多问题。主要体现在：
1、在社会发展方面，流动人口增多，造成城镇住房紧张、交通拥挤、犯罪率上升、社会治安形势严峻，农民工落户问题突出等；
2、城市化引发粮食危机。 城市化导致城镇用地过多，出现土地撂荒，土地产出为零，甚至为负数的情况，造成土地资源的严重浪费和土地配置的不经济。
3、城市化对能源,包括电、煤、石油、燃气等需求都将有巨大的增长,对生态环境必将产生强大的压力。
因此，正确认识城市化所带来的成果，采取必要的措施认真解决其带来的负面影响， 最大程度的使城市化的成果由城市居民、农民共享， 才更具有现实意义。
