随着地球上人口增加,资源减少,新技术运用越来越广泛。我国是一个人口大国,农民所占比例高,又正处于城市化的进程中,建筑发展较快,但污染高、耗能高、资源浪费现象太严重,在建筑工程采用新技术、新能源成必不可少的趋势,能有效地节能减排,减少污染,增加资源利用率,是我国建筑业发展的重要的方向。 As the population on earth increases and resources are reduced, the use of new technologies is becoming more and more widespread. China is a populous country with a high proportion of peasants and is in the process of urbanization with rapid development of buildings. However, with high pollution, high energy consumption and waste of resources, China is adopting new technologies and new energy sources in construction projects An indispensable trend, which can effectively save energy and reduce emissions, reduce pollution and increase resource utilization, is an important direction for the development of China's construction industry.
