问答题 案例分析题

材料一:

改革开放30多年,我国城镇化进程不断加快,平均每年提升1.01个百分点。城镇化进程应该有一个科学的把握。除了总体发展速度要适度外,各地区的城镇化进度应与各自不同的经济发展水平、经济结构和人口密度相适应。在农村地区小城镇发展过程中,应避免出现重速度、轻质量的局面。

材料二:

2014年8月8日,世界卫生组织将今年3月在几内亚等国家暴发的埃博拉疫情定为“国际突发公共卫生事件”,抗击埃博拉成为世界性联合行动。人们对病毒的认识和斗争是不断前进的。1976年最早暴发埃博拉疫情时人们不知道病毒的来源和传播方式,因此没有有效防制手段;随着研究的深入,现在可以确定病毒来源于动物,人与人主要是通过接触传播,因此主要防止疫情蔓延的办法是把患者隔离,切断传染源,控制疫情;目前尚无有效抗病毒疫苗和治疗药物,防止疫情暴发也无有效办法,人类对该病毒的认识防控还是一个相当长期艰巨的任务。人类要彻底战胜埃博拉病毒,需要准确掌握发生条件、传播方式、研制疫苗等许多步骤,是一个在认识和实践中不断积累经验而逐步实现的过程。现在中美等国医学界正在加紧研究针对该病毒的疫苗。最新消息,美国在非洲感染埃博拉病毒的两位医生在回国接受试验疫苗后,已出院与家人团聚。随着研究的不断深入,相信人类与病毒的斗争会在不远将来最终取得成功。

结合材料一,运用辩证唯物论知识,谈谈如何实现我国城镇化的“科学发展”?
