美国学者的实验研究表明,人口密集和拥挤产生的环境混乱,容易造成心理压力和紧张,进而产生其他社会疾病。进一步的实证研究又表明,美国在发达社会经济条件下实际人口密度并没有超出适度范围,并不存在普遍的拥挤和密集问题;在排除了阶级、种族、教育等因素后,某些严重的社会症状与居住密度或拥挤程度没有明显的因果关系。然而,对中国等人口众多的发展中国家来说,人口密集和居住拥挤是无法回避的现实,需要通过科学规划与管理解决所面临的问题。 Experimental studies by American scholars have shown that chaos in crowded and crowded environments easily causes psychological stress and tension, which in turn leads to other social diseases. Further empirical research shows that the actual population density of the United States does not go beyond the proper range under developed social and economic conditions and that there is no universal problem of overcrowding and congestion. After excluding class, race and education, some serious social issues There is no obvious causal relationship between symptoms and residence density or crowding. However, for a large population of developing countries such as China, dense population and overcrowded living are unavoidable realities that need to be solved through scientific planning and management.
